A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 91 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 92 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 99 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 109 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 110 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 111 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 112 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 113 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 114 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 115 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 116 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 117 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Make sure you have the anti-theft code for the audio system or the navigation system (if equipped), then write down the audio presets. 2. Make sure the ignition switch is OFF. 3. Disconnect the negative battery cable, then disconnect the positive cable, and wait at least 3 minutes. 4. Remove the driver's dashboard lower cover. 5. Disconnect the connectors from the fuse side of the under-dash fuse/relay box (A). 6. Remove the mounting bolt, and pull the fuse/relay box away from the body. 7. Disconnect the connectors from the back side of the under-dash fuse/relay box, then remove the under-dash fuse/relay box. 8. Carefully remove the relays by prying under the base of the relay. NOTE: Do not use pliers. Pliers will damage the relays, which could cause the engine to stall or not start. Installation 1. Install the relays and connect the connectors to the under-dash fuse/relay box, then install the under-dash fuse/relay box in the reverse order of removal. 2. Install the removed parts in the reverse order of removal. 3. Connect the positive cable to the battery, then connect the negative cable to the battery. 4. Register the immobilizer system with the HDS. NOTE: The imoes unit is built into the MICU which is part of the under-dash fuse/relay box. Because of this construction, the imoes must be registered, or the vehicle will not start. 5. Enter the anti-theft code for the audio system or the navigation system (if equipped), then enter the audio presets. Set the clock (on vehicles without navigation). 6. Confirm that all systems work properly.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 224 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 225 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 242 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape.

Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 244 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 247 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity.

To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 249 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 250 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Jumping the SCS line after turning the ignition switch OFF cancels this function. Disconnecting the PCM during this function, without jumping the SCS line first, can damage the PCM. 1. Jump the SCS line with the HDS. 2. Remove the cover (A). 3. Lift up the under-hood fuse/relay box (D). 4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C have symbols (A=Square, B=triangle, C=circle) embossed on them for identification. 5. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check.

Connect one side of the patch cord (A) terminals to a commercially available digital multimeter (B), and connect the other side of the patch cord terminals to a commercially available banana jack (Pomona Electronics Tool No. 3563 or equivalent) (C). 7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the tips into the terminals. NOTE: For accurate results, always use the pin probe (male). - To prevent damage to the connector terminals, do not insert test equipment probes, paper clips, or other substitutes as they can damage the terminals. Damaged terminals cause a poor connection and an incorrect measurement. - Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.

Stored data based on failed parts should be cleared by using the CLEAR COMMAND of the HDS, if parts are replaced. The HDS has three kinds of clear commands to meet this purpose. They are DTC clear, PCM reset, and CKP pattern clear. DTC clear command erases all stored DTC codes, freeze data, on-board snapshot, and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting. The PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all specific data to correct the system except CKP pattern. If the CKP pattern data in the PCM was cleared, you must do the CKP pattern learn procedure. The CKP pattern clear command erases only CKP pattern data. This command is for repair of a misfire or the CKP sensor. Scan Tool Clear Command If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the PCM, and it clears all commands at the same time (CKP pattern learn, idle learn, readiness codes, freeze data, on-board snapshot, and DTCs). After you clear all commands, you then need to do these procedures, in this order: PCM idle learn procedure.; CKP pattern learn procedure; Test-drive to set readiness codes to complete . DTC Clear 1. Clear the DTC with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. PCM Reset NOTE:If the low fuel indicator is blinking, the PCM can not be reset with the HDS. To reset the PCM, do the low fuel indicator troubleshooting . 1. Reset the PCM with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. 5. Do the PCM idle learn procedure, CKP Pattern Clear/CKP Pattern Learn Clear/Learn Procedure (with the HDS) 1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 2. Turn the ignition switch ON (II). 3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting 4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS. 5. Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.

Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on. 2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the transmission in 2 position. 3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm down to 3,000 rpm with the transmission in 2 position. 4. Repeat step 2 and 3 several times. 5. Turn the ignition switch OFF. 6. Turn the ignition switch ON (II), and wait 30 seconds. How to End a Troubleshooting Session (required after any troubleshooting) 1. Reset the PCM with the HDS. 2. Do the PCM idle learn procedure. 3. Turn the ignition switch OFF. 4. Disconnect the HDS from the DLC. NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the HDS. Updating the ECM/PCM Updating the PCM Special Tools Required - Honda diagnostic system (HDS) tablet tester - Honda interface module (HIM) and an iN workstation with HDS and CM update software - HDS pocket tester - GNA600 and an iN workstation with HDS and CM update software Use any one of these update tools. NOTE: Use this procedure when you need to update the PCM during a troubleshooting procedures. - Make sure the HDS/HIM has the latest software version. - Before you update the PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. - Never turn the ignition switch OFF during the update. If there is a problem with the update, leave the ignition switch ON. - To prevent PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update. - To ensure the latest program is installed, do PCM update whenever the PCM is substituted or replaced. - You cannot update PCM with a program it already has. It will only accept a new program. - High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. - If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. 1. Turn the ignition switch ON (II), but do not start the engine. 2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 3. Make sure the HDS communicates with the PCM and other vehicle systems.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Steering and Suspension > Relays and Modules - Wheels and Tires > Tire Pressure Monitor Receiver / Transponder > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 398 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2.

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Relays and Modules > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision Power Window Control Module: Technical Service Bulletins Body - Power Window Diagnostics Revision 10-011 March 5, 2010 Applies To: See VEHICLES AFFECTED Service Manual Update: Power Window Goes Up and Reverses On Its Own, Is Slow to Open and Close, or Squeals, Creaks, Clunks, or Clicks BACKGROUND The information in this service bulletin addresses three power window problems that are not currently covered in the service manuals. VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0).

Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 888 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 906 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 907 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 908 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 909 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 910 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 911 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 912 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 913 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 914 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 989 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 990 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 997 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1007 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1008 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1009 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1010 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1011 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1012 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1013 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1014 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 1015 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Steering and Suspension > Sensors and Switches - Wheels and Tires > Tire Pressure Sensor > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 1036 A TPMS sensor tool is used for troubleshooting and replacing the TPMS sensors. See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Sensors and Switches > Sensors and Switches - Steering and Suspension > Sensors and Switches - Wheels and Tires > Tire Pressure Sensor > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 1037 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

SENSOR POSITION CHECK When the TPMS sets a DTC, it refers to Tire 1, Tire 2, Tire 3, or Tire 4. In the service manual, the tire number is the sensor number. For example, Tire 2 is sensor 2. However, the tire number is not the tire position. To diagnose or repair the vehicle, do the sensor position check to find the location of the problem tire (or sensor) on the vehicle. 1.

BACKGROUND New tools were developed to help you diagnose and correct a pulling and/or steering wheel off-center issue. There is a diagnosis worksheet included to take on your test-drive and record your findings. These values are used to build the 15-digit DTC (diagnostic trouble code) that is required for your warranty claim. The last step in each repair procedure helps you create the correct code. In the rare case that you have to repair a vehicle that pulls and has the steering wheel off-center, use REPAIR PROCEDURE B to file your warranty claim. For more information, refer to Training Module SSC 44 - Steering Drift or Pull Interactive Service Bulletin. PROBABLE CAUSES Several conditions can cause the vehicle to pull or drift: ^ Wheel alignment ^ Tires ^ Off-center steering wheel (no pulling or drifting, but a customer may believe this is the case) CORRECTIVE ACTION Diagnose the problem using the special tools and the worksheet on page 4 that guides you to one of four repair procedures. TOOL INFORMATION Centering Tape (enough to diagnose 240 vehicles): T/N O7AAJ-001A300 Steering Drift Set Level: T/N 07AAJ-00100 Steering Drift Set: T/N O7MJ-001A140 Replacement Weight for Steering Drift Set: T/N 07AAJ-001A400 WARRANTY CLAIM INFORMATION In warranty: The normal warranty applies.

Out of warranty: Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work. TOOL DESCRIPTIONS The holding force gauge measures the amount of pull on the vehicle. It is a bracket that counts as one weight, plus five removable weights. During the test-drive, attach the bracket and the weights to the steering wheel on the side opposite the pulling direction. For example, if the vehicle pulls to the right, attach the bracket and weights to the left side of the steering wheel. Start with the maximum amount of weight on the steering wheel, and remove the weights until the vehicle drives in a straight line. When recording the pull on the worksheet, write down the direction of the pull (lefi or right) and the number of weights required to balance the pull (one through six). For example, if you have the bracket and two weights on the steering wheel, then record this as three weights. NOTE: The bracket counts as one weight. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Customer Interest for Alignment: > 06-068 > May > 09 > Steering/Suspension - Vehicle Pulls Left/Right > Page 1160 The road crown gauge measures the amount of road crown. Almost all roads have a crown to help drain water during rainstorms. Use the suction cup to attach the road crown gauge bracket to the vehicle in a vertical position. If necessary, bend the bracket until the gauge is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. There are two ways to calibrate the gauge: ^ Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is on the zero mark. ^ If you do not have a perfectly flat surface, park the vehicle on a reasonably flat surface and note the gauge reading. Turn the vehicle 1800 and, with the tires in the same spot, note the new gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3 and, after moving the vehicle, the gauge reads -1, then the difference is 4 degrees. Position the gauge to read +1. NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test-drive. If you plan to have an assistant help you during the test-drive, calibrate the gauge while both of you are sitting in the vehicle.

Place the sticker on the steering wheel when the steering wheel is straight. When you test-drive the vehicle, you can read how many millimeters the steering wheel is off-center. NOTE: If the vehicle is pulling, repairing the pull may correct the steering wheel offset.

Swap wheels 2 and 4 on the passenger's side of the vehicle, and test-drive again. ^ If the pull goes away, replace the tire on wheel 2, then go to step 3. ^ If the pull does not go away, put wheels 2 and 4 back to their original positions, and go to step 2. 2. Swap wheels 1 and 3 on the driver's side of the vehicle, and test-drive again. ^ If the pull goes away, replace the tire on wheel 1, then go to step 3. ^ If the pull does not go away, use a known-good tire in position 1 and continue diagnosis. 3. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. REPAIR PROCEDURE B Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Customer Interest for Alignment: > 06-068 > May > 09 > Steering/Suspension - Vehicle Pulls Left/Right > Page 1164 1. Place the vehicle on a commercially available, computerized, four-wheel alignment rack, and record the following measurements. Follow the equipment manufacturer's instructions. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. 2. If any measurement is out of specification, inspect the front suspension for any damage. Repair any damaged parts before continuing your diagnosis. 3. Determine how the front wheel camber is affecting the pull. Pick the combination of left- and right-front camber that best matches the vehicle you are repairing, then note the camber thrust direction for that combination: NOTE: ^ If the camber of both front wheels is negative, but one wheel is grossly more negative than the other, the camber thrust direction will be opposite the wheel with more negative camber (for example, if the left-front wheel is more negative, the camber thrust direction is right). ^ If the camber of both front wheels is positive, but one wheel is grossly more positive than the other, the camber thrust direction will be the same as the wheel with more positive camber (for example, if the left-front wheel is more positive, the camber thrust direction is left). 4. Determine how the camber needs to be adjusted. 5. Adjust the camber as needed. Front Camber Adjustment, Double Wishbone Suspension Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Customer Interest for Alignment: > 06-068 > May > 09 > Steering/Suspension - Vehicle Pulls Left/Right > Page 1165 ^ Loosen the front subframe bolts. See the applicable service manual for more information. NOTE: The front wheels are being viewed from the rear of the vehicle. ^ Depending which way you need to shift the subframe, insert a pry bar between the subframe and body at both the front and rear positions of the subframe. NOTE: Be careful not to damage the vehicle. You could bend and damage the frame and/or body if you apply too much pressure. ^ Press on both pry bars to shift the subframe. It will move only a few millimeters. This should adjust the camber about 0.2-0.5°. ^ While holding the subframe in place, have an assistant torque the subframe bolts to their proper torque. Front Camber Adjustment, Strut Suspension ^ Raise the vehicle, and remove the front tires. ^ Loosen the damper pinch bolts and the flange nuts. ^ Adjust the camber by moving the bottom of the damper within the range of the damper pinch bolt free play. NOTE: Some vehicles have special pinch bolts that allow more adjustment. For more information, refer to the parts catalog. ^ Tighten the damper pinch bolts to the specified torque. ^ Reinstall the front wheels and lower the vehicle.

Test-drive the vehicle to make sure it no longer pulls. If the steering wheel is now off-center by more than 2 mm, go to REPAIR PROCEDURE C. 7. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. REPAIR PROCEDURE C 1. Make sure the steering wheel is centered. ^ Turn the steering wheel all the way to the right until it stops. ^ Turn the steering wheel all the way to the left, and count the number of revolutions until it stops. ^ Divide the number of revolutions in half, and turn the steering wheel until it is centered. For example, if it takes four revolutions of the steering wheel to go from lock to lock, then two turns is centered. ^ If the steering wheel is off-center by a large amount (20 mm or more), it may not be centered on the steering column shaft. Reinstall the steering wheel before going to step 2. 2. Place the vehicle on a lift, turn the steering wheel until it is centered, and then raise the vehicle. 3. Adjust the tie-rods. Use your measurements from question 13 of the test-drive to make your adjustment.

BACKGROUND New tools were developed to help you diagnose and correct a pulling and/or steering wheel off-center issue. There is a diagnosis worksheet included to take on your test-drive and record your findings. These values are used to build the 15-digit DTC (diagnostic trouble code) that is required for your warranty claim. The last step in each repair procedure helps you create the correct code. In the rare case that you have to repair a vehicle that pulls and has the steering wheel off-center, use REPAIR PROCEDURE B to file your warranty claim. For more information, refer to Training Module SSC 44 - Steering Drift or Pull Interactive Service Bulletin. PROBABLE CAUSES Several conditions can cause the vehicle to pull or drift: ^ Wheel alignment ^ Tires ^ Off-center steering wheel (no pulling or drifting, but a customer may believe this is the case) CORRECTIVE ACTION Diagnose the problem using the special tools and the worksheet on page 4 that guides you to one of four repair procedures.

It is a bracket that counts as one weight, plus five removable weights. During the test-drive, attach the bracket and the weights to the steering wheel on the side opposite the pulling direction. For example, if the vehicle pulls to the right, attach the bracket and weights to the left side of the steering wheel. Start with the maximum amount of weight on the steering wheel, and remove the weights until the vehicle drives in a straight line. When recording the pull on the worksheet, write down the direction of the pull (lefi or right) and the number of weights required to balance the pull (one through six). For example, if you have the bracket and two weights on the steering wheel, then record this as three weights. NOTE: The bracket counts as one weight.

Almost all roads have a crown to help drain water during rainstorms. Use the suction cup to attach the road crown gauge bracket to the vehicle in a vertical position. If necessary, bend the bracket until the gauge is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. There are two ways to calibrate the gauge: ^ Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is on the zero mark. ^ If you do not have a perfectly flat surface, park the vehicle on a reasonably flat surface and note the gauge reading. Turn the vehicle 1800 and, with the tires in the same spot, note the new gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3 and, after moving the vehicle, the gauge reads -1, then the difference is 4 degrees. Position the gauge to read +1. NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test-drive. If you plan to have an assistant help you during the test-drive, calibrate the gauge while both of you are sitting in the vehicle.

NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. 2. If any measurement is out of specification, inspect the front suspension for any damage. Repair any damaged parts before continuing your diagnosis. 3. Determine how the front wheel camber is affecting the pull. Pick the combination of left- and right-front camber that best matches the vehicle you are repairing, then note the camber thrust direction for that combination: NOTE: ^ If the camber of both front wheels is negative, but one wheel is grossly more negative than the other, the camber thrust direction will be opposite the wheel with more negative camber (for example, if the left-front wheel is more negative, the camber thrust direction is right). ^ If the camber of both front wheels is positive, but one wheel is grossly more positive than the other, the camber thrust direction will be the same as the wheel with more positive camber (for example, if the left-front wheel is more positive, the camber thrust direction is left). 4. Determine how the camber needs to be adjusted. 5. Adjust the camber as needed.

Swap wheels 1 and 3 on the driver's side of the vehicle, and test-drive again. ^ If the pull goes away, replace the tire on wheel 1, then go to step 3. ^ If the pull does not go away, use a known-good tire in position 1 and continue diagnosis. 3. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. REPAIR PROCEDURE B Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 1197 1. Place the vehicle on a commercially available, computerized, four-wheel alignment rack, and record the following measurements. Follow the equipment manufacturer's instructions. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. 2. If any measurement is out of specification, inspect the front suspension for any damage. Repair any damaged parts before continuing your diagnosis. 3. Determine how the front wheel camber is affecting the pull. Pick the combination of left- and right-front camber that best matches the vehicle you are repairing, then note the camber thrust direction for that combination: NOTE: ^ If the camber of both front wheels is negative, but one wheel is grossly more negative than the other, the camber thrust direction will be opposite the wheel with more negative camber (for example, if the left-front wheel is more negative, the camber thrust direction is right). ^ If the camber of both front wheels is positive, but one wheel is grossly more positive than the other, the camber thrust direction will be the same as the wheel with more positive camber (for example, if the left-front wheel is more positive, the camber thrust direction is left). 4. Determine how the camber needs to be adjusted. 5. Adjust the camber as needed. Front Camber Adjustment, Double Wishbone Suspension Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 1198 ^ Loosen the front subframe bolts. See the applicable service manual for more information. NOTE: The front wheels are being viewed from the rear of the vehicle. ^ Depending which way you need to shift the subframe, insert a pry bar between the subframe and body at both the front and rear positions of the subframe. NOTE: Be careful not to damage the vehicle. You could bend and damage the frame and/or body if you apply too much pressure. ^ Press on both pry bars to shift the subframe. It will move only a few millimeters. This should adjust the camber about 0.2-0.5°. ^ While holding the subframe in place, have an assistant torque the subframe bolts to their proper torque. Front Camber Adjustment, Strut Suspension ^ Raise the vehicle, and remove the front tires. ^ Loosen the damper pinch bolts and the flange nuts. ^ Adjust the camber by moving the bottom of the damper within the range of the damper pinch bolt free play. NOTE: Some vehicles have special pinch bolts that allow more adjustment. For more information, refer to the parts catalog. ^ Tighten the damper pinch bolts to the specified torque. ^ Reinstall the front wheels and lower the vehicle. Bounce the front of the vehicle several times to stabilize the suspension. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 1199 6. Test-drive the vehicle to make sure it no longer pulls. If the steering wheel is now off-center by more than 2 mm, go to REPAIR PROCEDURE C. 7. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. REPAIR PROCEDURE C 1. Make sure the steering wheel is centered. ^ Turn the steering wheel all the way to the right until it stops. ^ Turn the steering wheel all the way to the left, and count the number of revolutions until it stops. ^ Divide the number of revolutions in half, and turn the steering wheel until it is centered. For example, if it takes four revolutions of the steering wheel to go from lock to lock, then two turns is centered. ^ If the steering wheel is off-center by a large amount (20 mm or more), it may not be centered on the steering column shaft. Reinstall the steering wheel before going to step 2. 2. Place the vehicle on a lift, turn the steering wheel until it is centered, and then raise the vehicle. 3. Adjust the tie-rods. Use your measurements from question 13 of the test-drive to make your adjustment. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 1200 ^ If the wheels are pointed to the right, shorten the driver's side tie-rod, and lengthen the passenger's side. ^ If the wheels are pointed to the left, shorten the passenger's side tie-rod, and lengthen the driver's side. ^ Each 360° turn of the tie-rod equals about 8 mm of steering wheel adjustment. For example, a steering wheel is off-center by 4 mm with the front wheels pointed right (when the steering wheel is centered). To correct the off-center, shorten the driver's side tie-rod by a half-turn, and lengthen the passenger's side tie-rod by a half-turn. 4. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC.

Before adding any leak-detection dye, check to see if there is dye in the system now. ^ Check for a label in the engine compartment indicating that fluorescent leak-detection dye has been added to the system. ^ Dye may have been added even though no label is present. To confirm this: - Put on the fluorescence-enhancing glasses, and remove the low-side service port sealing cap. - Direct the ultraviolet lamp into the valve stem area. If dye has been previously added, the lubricant traces will have a bright yellow fluorescent glow. You may need to press the port's valve stem briefly to release some lubricant and dye from the system. ^ If there is no dye in the system, go to step 2. ^ If there is dye in the system, go to step 5. Do not add more dye. 2. Add the dye. NOTE: Air and moisture must be evacuated from the universal connect set if it is being used for the first time, or if it has been stored with the control valve open. If the air and moisture have been evacuated, go to step 3; otherwise do the following: (a) Attach the empty dye capsule (provided in the dye kit) to the control valve fitting. (b) Attach the service valve fitting (provided in the kit) to the empty dye capsule. (c) Attach the low-side hose of the A/C recovery and charging station, and open the quick coupler's hand-wheel valve. Then open the control valve (black knob) on the universal connect set. (d) Following the manufacturer's instructions for your recovery and charging station, evacuate the universal connect set for approximately 3 minutes. (e) When evacuation is complete, be sure the set's control valve is closed (finger tight), and disconnect the NC recovery and charging station. (f) Remove the service valve fitting and the empty dye capsule from the set, and store them for future use. NOTE: ^ Check the refrigerant charge level. There must be enough refrigerant in the system to operate the A/C compressor and to circulate refrigerant oil. ^ If the refrigerant charge is too low, recover the remaining amount and recharge the system before adding any dye. (g) Start the vehicle and operate the A/C system. Follow your A/C refrigerant recovery and charging station's operating instructions for low-side charging to install the dye. * NOTE: Only 0.05 lb (0.02 kg) of refrigerant is needed to push the dye into the A/C system.* (h) Once the refrigerant charge is programmed, open the control valve on the set to allow the dye to enter the system. (i) After the dye capsule clears, allow the low-side of the A/C system to reach its lowest operating pressure, then quickly close both the service equipment's low-side coupler valve and the control valve on the set. (j) Remove the set from the vehicle by releasing its quick coupler. Remove the empty dye capsule from the service valve fitting. Return the hose, control valve, and service-valve fitting to the storage case. * NOTE: Store the hose with the control valve closed. This will retain a small amount of refrigerant in the hose so it does not have to be evacuated the next time you use it.* (k) Fill out an identification label (provided in the kit), and attach it to a location near the A/C charge label. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fluids > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection > Page 1338 3. Connect the universal connect set and the Tracer- Stick dye capsule: (a) Be sure the quick coupler and control valves on the set are closed. (b) Remove the low-side service port sealing cap, and connect the set to the low-side service port using the quick coupler. (c) Hold a new dye capsule so that the embossed arrow is pointing up. Remove the black end cap, and carefully attach the capsule to the control valve fitting. NOTE: The capsule must be held with the embossed arrow pointing up or the dye will leak out of the capsule. (d) Turn the capsule so the embossed arrow is pointing down. Remove the orange end cap, and carefully attach the service valve fitting provided in the kit (finger tight). NOTE: The capsule must be held with the embossed arrow pointing down or the dye will leak out. 4. Connect the NC service equipment: With the universal connect set and dye capsule attached to the vehicle's low-side service port, connect the A/C refrigerant recovery and charging station's low-side hose quick coupler to the service valve fitting. Open the blue hand-wheel valves on both quick couplers. Leave the control valve (black knob) on the universal connect set closed. NOTE: * ^ If you have recovered refrigerant to weigh it as part of your diagnostics, or if there is a low charge, it is more efficient to recharge the system using normal procedures before installing the universal connect set. Dye can then be added using approximately 0.05 lb (0.02 kg) of refrigerant.* ^ You do not need to connect the service equipment's high-side hose to the vehicle to install the dye. If the high-side hose is connected, make sure its coupler valve is closed before proceeding. ^ Do not use the A/C recovery and charging station to recover or evacuate the A/C system when a full dye capsule is attached. The dye will be drawn into the service equipment instead of being added to the vehicle's A/C system. 5. Inspect the A/C system for leaks: (a) Run the A/C system for at least 15 minutes to circulate the dye through the system. Large leaks will be seen immediately as a fluorescent yellow glow. Smaller leaks may require at least 24 hours of vehicle operation before they become visible. Operate the A/C system as much as possible during this time to keep the dye circulating. (b) Stop the vehicle's engine and inspect the system for leaks using the ultraviolet (UV) lamp and fluorescence-enhancing glasses from the kit. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fluids > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection > Page 1339 Low ambient light conditions (a dark work area) will aid in locating the leak. NOTE: Not all UV lamps work well with all types of fluorescent dye. Use only the lamp provided in the kit to inspect for leaks. (c) Inspect the entire system. Be sure to check these locations: ^ damaged and corroded areas ^ fittings ^ hose-to-line couplings ^ refrigerant controls ^ service ports ^ brazed or welded areas ^ areas near attachment points (d) Check for evaporator leaks by illuminating the evaporator drain tube area with the UV lamp and glasses. (e) After repairing a leak, remove any fluorescent residue using the GLO-AWAY dye cleaner from the kit and hot water (follow the instructions on the bottle).

If the instructions described are not properly followed, the airbags could accidentally deploy and cause damage or injuries. - Except when performing electrical inspections, always turn the ignition switch OFF, disconnect the negative cable from the battery, then wait for 3 minutes before starting work. NOTE: The SRS memory is not cleared even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. - Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs. - Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation. - Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors. - Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury. - Do not put objects on the front passenger's airbag. - The original audio and navigation system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system or the navigation system (if equipped), then write down the audio presets before disconnecting the negative cable from the battery. - Before returning the vehicle to the customer, enter the anti-theft codes for the audio system or the navigation system (if equipped), then enter the audio presets; set the clock. Steering-related Precautions Cable Reel Alignment - Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, and the horn inoperative. Center the cable reel whenever you do the following. Installation of the steering wheel - Installation of the cable reel - Installation of the steering column - Other steering-related adjustment or installation - Do not disassemble the cable reel. - Do not apply grease to the cable reel. - If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Airbag Handling and Storage Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, observe the following precautions. - Store the removed airbag with the pad surface up. Never put anything on the airbag. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 1355 - To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water. - Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200 °F/93 °C) - Never perform electrical inspections to the airbags, such as measuring resistance. - Do not position yourself in front of the airbag during removal, inspection, or replacement. - For proper disposal of a damaged airbag, refer to airbag disposal. - The side curtain airbag inflator assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag assembly, never do the following items: Handle the flexible bag. - Drop the curtain airbag. - Cut, tear, and peel the tapes.

The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Restraint Systems/Air Bag Systems/Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 1357 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1376 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1377 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1395 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1396 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1397 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1398 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1399 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1400 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1401 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 1402 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1434 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1435 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1452 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1453 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1454 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1455 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1456 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1457 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1458 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1459 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1460 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

When the TPMS control unit detects low pressure in a tire, or a problem in the system, it turns on the appropriate indicator. ^ If low tire pressure is detected in one or more tires, the low tire pressure indicator comes on. ^ If a problem in the system is detected, the TPMS indicator comes on. ^ If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. If the system is OK, the TPMS indicator and the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If they don't, there is a problem with the system. If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit will set one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, the control unit turns off the indicators and stores the DTC(s). However, if the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator(s). NOTE: Tire pressures increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures can also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18°F (10°C) changes tire pressure by about 10 kPa (0.1 kgf/cm2, 1.5 psi). If the temperature drops, tire pressure could decrease just enough to turn on the low tire pressure indicator, but later, the tire temperature could increase enough to turn the indicator off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range 168 to 220 kPa (1.7 to 2.2 kgf/cm2, 24 to 32 psi). If a problem is detected in the system, the TPMS indicator comes on and stays on until the system returns to normal with most DTCs. If DTC 81, 83 or 85 is set, the TPMS indicator goes off only when the ignition switch is turned to LOCK (0). When a flat tire is replaced with the spare tire, the TPMS indicator comes on (DTC 32, 34, 36 or 38) because the system is no longer receiving the signal from the tire's transmitter. This is not a problem with the spare tire.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Service Reminder Indicators > Malfunction Indicator Lamp > Component Information > Description and Operation Malfunction Indicator Lamp: Description and Operation Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness Codes) The vehicle has certain "readiness codes" that are part of the on-board diagnostics for the emissions systems. If the vehicle's battery has been disconnected or gone dead, if the DTCs have been cleared, or if the PCM has been reset, these codes are reset. In some states, part of the emissions testing is to make sure these codes are set to complete. If all of them are not set to complete, the vehicle may fail the test, or the test cannot be finished. To check if the readiness codes are set to complete, turn the ignition switch ON (II), but do not start the engine. The MIL will come on for 15-20 seconds. If it then goes off, the readiness codes are complete'. If it flashes five times, one or more readiness codes are not complete. To set each code, drive the vehicle or run the engine as described in the procedures.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Wheels and Tires > Relays and Modules - Wheels and Tires > Tire Pressure Monitor Receiver / Transponder > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 1562 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Wheels and Tires > Sensors and Switches - Wheels and Tires > Tire Pressure Sensor > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 1585 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

When the TPMS control unit detects low pressure in a tire, or a problem in the system, it turns on the appropriate indicator. ^ If low tire pressure is detected in one or more tires, the low tire pressure indicator comes on. ^ If a problem in the system is detected, the TPMS indicator comes on. ^ If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. If the system is OK, the TPMS indicator and the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If they don't, there is a problem with the system. If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit will set one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, the control unit turns off the indicators and stores the DTC(s). However, if the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator(s). NOTE: Tire pressures increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures can also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18°F (10°C) changes tire pressure by about 10 kPa (0.1 kgf/cm2, 1.5 psi). If the temperature drops, tire pressure could decrease just enough to turn on the low tire pressure indicator, but later, the tire temperature could increase enough to turn the indicator off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range 168 to 220 kPa (1.7 to 2.2 kgf/cm2, 24 to 32 psi). If a problem is detected in the system, the TPMS indicator comes on and stays on until the system returns to normal with most DTCs. If DTC 81, 83 or 85 is set, the TPMS indicator goes off only when the ignition switch is turned to LOCK (0). When a flat tire is replaced with the spare tire, the TPMS indicator comes on (DTC 32, 34, 36 or 38) because the system is no longer receiving the signal from the tire's transmitter. This is not a problem with the spare tire.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Towing Information > System Information > Service and Repair Towing Information: Service and Repair Towing If the vehicle needs to be towed, call a professional towing service. Never tow the vehicle behind another vehicle with a rope or chain. It is very dangerous. Emergency Towing There are three popular methods of towing a vehicle. Flat-bed Equipment - The operator loads the vehicle on the back of a truck. This is the best way of transporting the vehicle. To accommodate flat-bed equipment, the vehicle is equipped with front towing hooks (A), front tie down hook slots (B), a rear towing hook (C), and rear tie down hook slots (D). The towing hooks can be used with a winch to pull the vehicle onto the truck, and the tie down slots can be used to secure the vehicle to the truck. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Towing Information > System Information > Service and Repair > Page 1724 Wheel Lift Equipment - The tow truck uses two pivoting arms that go under the tires (front or rear) and lift them off the ground. The other two wheels remain on the ground. This is an acceptable way of towing the vehicle. Sling-type Equipment - The tow truck uses metal cables with hooks on the ends. These hooks go around parts of the frame or suspension, and the cables lift that end of the vehicle off the ground. The vehicle's suspension and body can be seriously damaged if this method of towing is attempted. This method of towing the vehicle is unacceptable. If the vehicle cannot be transported by a flat-bed, it should be towed with the front wheels off the ground. If the vehicle is damaged, and must be towed with the front wheels on the ground, or with all four wheels on the ground, do this: Manual Transmission - Release the parking brake. - Shift the transmission to neutral. - Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock - Make sure all accessories are turned off to minimize battery current draw. Automatic Transmission - Release the parking brake. - Start the engine. - Shift to the D position, then to the N position. - Turn off the engine. - Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock - Make sure all accessories are turned off to minimize battery current draw. It is best to tow the vehicle no farther than 50 miles (80 km), and keep the speed below 35 mph (55 km/h). NOTICE: - Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shift the transmission or start the engine (automatic transmission), the vehicle must be transported on a flat-bed. - Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not designed to support the vehicle's weight. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Maintenance > Vehicle Lifting > Component Information > Service and Repair Vehicle Lifting: Service and Repair Lift and Support Points NOTE: If you are going to remove heavy components such as the suspension or the fuel tank from the rear of the vehicle, first support the front of the vehicle with tall safety stands. When substantial weight is removed from the rear of the vehicle, the center of gravity can change, causing the vehicle to tip forward on the lift. Vehicle Lift 1. Position the lift blocks (A) under the vehicle's front support points (B) and rear support points (C). 2. Raise the lift a few inches, and rock the vehicle gently to be sure it is firmly supported. 3. Raise the lift to its full height, and inspect the vehicle support points for solid contact with the lift blocks. Safety Stands To support the vehicle on safety stands, use the same support points (B and C) as for a vehicle lift. Always use safety stands when working on or under any vehicle that is supported only by a jack. Floor Jack 1. When lifting the front of the vehicle, set the parking brake. When lifting the rear of the vehicle, put the shift lever in reverse for manual transmission, or in the P position for automatic transmission. 2. Block the wheels that are not being lifted. 3. Position the floor jack under the front jacking bracket (A) or the rear jacking bracket (B). Center the jacking bracket on the jack lift platform (C), and jack up the vehicle high enough to fit the safety stands under it. 4. Position the safety stands under the support points, and adjust them so the vehicle is level. 5. Lower the vehicle onto the stands.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1736 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1754 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1755 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1756 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1759 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1760 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1761 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Actuators and Solenoids - Engine > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1762 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

(Cam angle is changed to obtain the desired EGR effect and reduce pumping loss). Operation At engine start, and high load - The rocker arm oil control valve is OFF. - Oil pressure enters secondary rocker arm B from the oil passage in the intake rocker shaft. This forces the VTEC switching piston into secondary rocker arm A against the return spring and disengages secondary arm A from secondary arm B to stop valve actuation. At cruise The rocker arm oil control valve switches oil pressure to the oil passage in the intake rocker arm shaft. Oil pressure then enters secondary rocker arm A, and it moves the VTEC switching piston in the rocker arm. This causes the VTEC switching piston to slide into secondary rocker arm B, locking secondary rocker arms A and B together.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK.

Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1825 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1826 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1827 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1828 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1829 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1830 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1831 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1832 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 1833 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

(Cam angle is changed to obtain the desired EGR effect and reduce pumping loss). Operation At engine start, and high load - The rocker arm oil control valve is OFF. - Oil pressure enters secondary rocker arm B from the oil passage in the intake rocker shaft. This forces the VTEC switching piston into secondary rocker arm A against the return spring and disengages secondary arm A from secondary arm B to stop valve actuation. At cruise The rocker arm oil control valve switches oil pressure to the oil passage in the intake rocker arm shaft. Oil pressure then enters secondary rocker arm A, and it moves the VTEC switching piston in the rocker arm. This causes the VTEC switching piston to slide into secondary rocker arm B, locking secondary rocker arms A and B together.

Remove the valves. 2. Slide the valve out of its guide about 10 mm (0.39 in.), then measure the guide-to-stem clearance with a dial indicator while rocking the stem in the direction of normal thrust (wobble method). ^ If the measurement exceeds the service limit, recheck it using a new valve. ^ If the measurement is now within the service limit, reassemble using a new valve. ^ If the measurement with a new valve still exceeds the service limit, go to step 3. 3. Subtract the valve stem O.D. (measured with a micrometer) from the valve guide I.D. (measured with an inside micrometer or ball gauge). Take the measurements in three places along the valve stem and three places inside the valve guide. The difference between the largest guide measurement and the smallest stem measurement should not exceed the service limit. Intake Valve Stem-to-Guide Clearance Standard (New): 0.02 - 0.05 mm (0.0008 - 0.0020 in.) Service Limit: 0.08 mm (0.003 in.) Exhaust Valve Stem-to-Guide Clearance Standard (New): 0.05 - 0.08 mm (0.0020 - 0.0031 in.) Service Limit: 0.11 mm (0.004 in.) Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve Guide > Component Information > Testing and Inspection > Page 1945 Valve Guide: Service and Repair Valve Guide Replacement Special Tools Required ^ Valve guide driver, 5.5 mm 07742-0010100 ^ Valve guide reamer, 5.5 mm 07HAH-PJ7A100 1. Inspect the valve stem-to-guide clearance. 2. As illustrated, use a commercially available air-impact valve guide driver (A) modified to fit the diameter of the valve guides. In most cases, the same procedure can be done using the valve guide driver and a conventional hammer. 3. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for about an hour. 4. Use a hot plate or oven to evenly heat the cylinder head to 300°F (50°C). Monitor the temperature with a cooking thermometer. Do not get the head hotter than 300°F (150°C); excessive heat may loosen the valve seats. 5. Working from the camshaft side, use the driver and an air hammer to drive the guide about 2 mm (0.1 in.) towards the combustion chamber. This will knock off some of the carbon and make removal easier. Hold the air hammer directly in line with the valve guide to prevent damaging the driver. Wear safety goggles or a face shield. 6. Turn the head over, and drive the guide out toward the camshaft side of the head. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve Guide > Component Information > Testing and Inspection > Page 1946 7. If a valve guide still won't move, drill it out with a 8 mm (5/16 in.) bit, then try again. NOTE: Drill guides only in extreme cases; you could damage the cylinder head if the guide breaks. 8. Take out the new guide(s) from the freezer, one at a time, as you need them. 9. Apply a thin coat of new engine oil to the outside of the new valve guide. Install the guide from the camshaft side of the head; use the valve guide driver to drive the guide to the specified installed height (A) of the guide (B). If you have all 16 guides to do, you may have to reheat the head. 10. Coat both the reamer and the valve guide with cutting oil. 11. Rotate the reamer clockwise to the full length of the valve guide bore. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve Guide > Component Information > Testing and Inspection > Page 1947 12. Continue to rotate the reamer clockwise while drawing it from the bore. 13. Thoroughly wash the guide in detergent and water to remove any cutting residue. 14. Check the clearance with a valve. Verify that a valve slides into the intake and exhaust valve guides without sticking. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve Seat > Component Information > Service and Repair Valve Seat: Service and Repair Valve Seat Reconditioning 1. Inspect the valve stem-to-guide clearance. If the valve guides are worn, replace them before cutting the valve seats. 2. Renew the valve seats in the cylinder head using a valve seat cutter. 3. Carefully cut a 45° seat, removing only enough material to ensure a smooth and concentric seat. 4. Bevel the upper edge of the seat with the 30° cutter and the lower edge of the seat with the 60° cutter. Check the width of the seat and adjust accordingly. 5. Make one more very light pass with the 45° cutter to remove any possible burrs caused by the other cutters. Valve Seat Width Intake: Standard (New): 1.25 - 1.55 mm (0.049 - 0.061 in.) Service Limit: 2.0 mm (0.08 in.) Exhaust: Standard (New): 1.45 - 1.75 mm (0.057 - 0.00 in.) Service Limit: 2.2 mm (0.09 in.) 6. After resurfacing the seat, inspect it for even valve seating. Apply Prussian Blue compound (A) to the valve face. Insert the valve in its original location in the head, then lift it and snap it closed against the seat several times. 7. The actual valve seating surface (B), as shown by the blue compound, should be centered on the seat. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve Seat > Component Information > Service and Repair > Page 1951 ^ If it is too high (closer to the valve stem), you must make a second cut with the 60° cutter to move it down, then one more cut with the 45° cutter to restore seat width. ^ If it is too low (closer to the valve edge), you must make a second cut with the 30° cutter to move it up, then one more cut with the 45° cutter to restore seat width. NOTE: The final cut should always be made with the 45° cutter. 8. Insert the intake and exhaust valves in the head, and measure the valve stem installed height (A). Intake Valve Stem Installed Height 9. If the valve stem installed height is beyond the service limit, replace the valve and recheck. If it is still beyond the service limit, replace the cylinder head; the valve seat in the head is too deep.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2069 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2070 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2087 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2088 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2089 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2090 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2091 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2092 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2093 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier.

Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2094 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2095 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2126 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2144 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2145 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2146 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2149 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2150 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2151 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Lamps and Indicators - Engine > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 2152 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2251 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2269 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2270 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2271 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2274 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2275 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2276 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Engine > Timing Components > Variable Valve Timing > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 2277 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

(Cam angle is changed to obtain the desired EGR effect and reduce pumping loss). Operation At engine start, and high load - The rocker arm oil control valve is OFF. - Oil pressure enters secondary rocker arm B from the oil passage in the intake rocker shaft. This forces the VTEC switching piston into secondary rocker arm A against the return spring and disengages secondary arm A from secondary arm B to stop valve actuation. At cruise The rocker arm oil control valve switches oil pressure to the oil passage in the intake rocker arm shaft. Oil pressure then enters secondary rocker arm A, and it moves the VTEC switching piston in the rocker arm. This causes the VTEC switching piston to slide into secondary rocker arm B, locking secondary rocker arms A and B together.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2365 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2375 2.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2383 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2384 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2385 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2386 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2387 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2388 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2389 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2390 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Radiator Cooling Fan Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 2391 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2529 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2530 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2547 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape.

Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2549 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2552 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2553 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2554 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 2555 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Jumping the SCS line after turning the ignition switch OFF cancels this function. Disconnecting the PCM during this function, without jumping the SCS line first, can damage the PCM. 1. Jump the SCS line with the HDS. 2. Remove the cover (A). 3. Lift up the under-hood fuse/relay box (D). 4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C have symbols (A=Square, B=triangle, C=circle) embossed on them for identification. 5. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check.

Stored data based on failed parts should be cleared by using the CLEAR COMMAND of the HDS, if parts are replaced. The HDS has three kinds of clear commands to meet this purpose. They are DTC clear, PCM reset, and CKP pattern clear. DTC clear command erases all stored DTC codes, freeze data, on-board snapshot, and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting. The PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all specific data to correct the system except CKP pattern. If the CKP pattern data in the PCM was cleared, you must do the CKP pattern learn procedure. The CKP pattern clear command erases only CKP pattern data. This command is for repair of a misfire or the CKP sensor. Scan Tool Clear Command If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the PCM, and it clears all commands at the same time (CKP pattern learn, idle learn, readiness codes, freeze data, on-board snapshot, and DTCs). After you clear all commands, you then need to do these procedures, in this order: PCM idle learn procedure.; CKP pattern learn procedure; Test-drive to set readiness codes to complete . DTC Clear 1. Clear the DTC with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. PCM Reset NOTE:If the low fuel indicator is blinking, the PCM can not be reset with the HDS. To reset the PCM, do the low fuel indicator troubleshooting . 1. Reset the PCM with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. 5. Do the PCM idle learn procedure, CKP Pattern Clear/CKP Pattern Learn Clear/Learn Procedure (with the HDS) 1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 2. Turn the ignition switch ON (II). 3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See: Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting 4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS. 5. Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.

Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on. 2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the transmission in 2 position. 3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm down to 3,000 rpm with the transmission in 2 position. 4. Repeat step 2 and 3 several times. 5. Turn the ignition switch OFF. 6. Turn the ignition switch ON (II), and wait 30 seconds. How to End a Troubleshooting Session (required after any troubleshooting) 1. Reset the PCM with the HDS. 2. Do the PCM idle learn procedure. 3. Turn the ignition switch OFF. 4. Disconnect the HDS from the DLC. NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the HDS. Updating the ECM/PCM Updating the PCM Special Tools Required - Honda diagnostic system (HDS) tablet tester - Honda interface module (HIM) and an iN workstation with HDS and CM update software - HDS pocket tester - GNA600 and an iN workstation with HDS and CM update software Use any one of these update tools. NOTE: Use this procedure when you need to update the PCM during a troubleshooting procedures. - Make sure the HDS/HIM has the latest software version. - Before you update the PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. - Never turn the ignition switch OFF during the update. If there is a problem with the update, leave the ignition switch ON. - To prevent PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update. - To ensure the latest program is installed, do PCM update whenever the PCM is substituted or replaced. - You cannot update PCM with a program it already has. It will only accept a new program. - High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. - If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. 1. Turn the ignition switch ON (II), but do not start the engine. 2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 3. Make sure the HDS communicates with the PCM and other vehicle systems.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2852 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2870 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2871 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2872 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2873 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2874 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2875 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2876 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2877 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 2878 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3083 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3084 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3091 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3093 2.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3101 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3102 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3103 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3104 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3105 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3106 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3107 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3108 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Diagrams > Diagram Information and Instructions > Page 3109 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Jumping the SCS line after turning the ignition switch OFF cancels this function. Disconnecting the PCM during this function, without jumping the SCS line first, can damage the PCM. 1. Jump the SCS line with the HDS. 2. Remove the cover (A). 3. Lift up the under-hood fuse/relay box (D). 4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C have symbols (A=Square, B=triangle, C=circle) embossed on them for identification. 5. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Testing and Inspection > How to Troubleshoot Circuits At the PCM > Page 3137 6. Connect one side of the patch cord (A) terminals to a commercially available digital multimeter (B), and connect the other side of the patch cord terminals to a commercially available banana jack (Pomona Electronics Tool No. 3563 or equivalent) (C). 7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the tips into the terminals. NOTE: For accurate results, always use the pin probe (male). - To prevent damage to the connector terminals, do not insert test equipment probes, paper clips, or other substitutes as they can damage the terminals. Damaged terminals cause a poor connection and an incorrect measurement. - Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.

Stored data based on failed parts should be cleared by using the CLEAR COMMAND of the HDS, if parts are replaced. The HDS has three kinds of clear commands to meet this purpose. They are DTC clear, PCM reset, and CKP pattern clear. DTC clear command erases all stored DTC codes, freeze data, on-board snapshot, and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting. The PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all specific data to correct the system except CKP pattern. If the CKP pattern data in the PCM was cleared, you must do the CKP pattern learn procedure. The CKP pattern clear command erases only CKP pattern data. This command is for repair of a misfire or the CKP sensor. Scan Tool Clear Command If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the PCM, and it clears all commands at the same time (CKP pattern learn, idle learn, readiness codes, freeze data, on-board snapshot, and DTCs). After you clear all commands, you then need to do these procedures, in this order: PCM idle learn procedure.; CKP pattern learn procedure; Test-drive to set readiness codes to complete . DTC Clear 1. Clear the DTC with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. PCM Reset NOTE:If the low fuel indicator is blinking, the PCM can not be reset with the HDS. To reset the PCM, do the low fuel indicator troubleshooting . 1. Reset the PCM with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. 5. Do the PCM idle learn procedure, CKP Pattern Clear/CKP Pattern Learn Clear/Learn Procedure (with the HDS) 1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 2. Turn the ignition switch ON (II). 3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See: Testing and Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting 4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS. 5. Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Engine Control Module > Component Information > Service and Repair > Procedures > Page 3148 Learn Procedure (without the HDS) 1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on. 2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the transmission in 2 position. 3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm down to 3,000 rpm with the transmission in 2 position. 4. Repeat step 2 and 3 several times. 5. Turn the ignition switch OFF. 6. Turn the ignition switch ON (II), and wait 30 seconds. How to End a Troubleshooting Session (required after any troubleshooting) 1. Reset the PCM with the HDS. 2. Do the PCM idle learn procedure. 3. Turn the ignition switch OFF. 4. Disconnect the HDS from the DLC. NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the HDS. Updating the ECM/PCM Updating the PCM Special Tools Required - Honda diagnostic system (HDS) tablet tester - Honda interface module (HIM) and an iN workstation with HDS and CM update software - HDS pocket tester - GNA600 and an iN workstation with HDS and CM update software Use any one of these update tools. NOTE: Use this procedure when you need to update the PCM during a troubleshooting procedures. - Make sure the HDS/HIM has the latest software version. - Before you update the PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. - Never turn the ignition switch OFF during the update. If there is a problem with the update, leave the ignition switch ON. - To prevent PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update. - To ensure the latest program is installed, do PCM update whenever the PCM is substituted or replaced. - You cannot update PCM with a program it already has. It will only accept a new program. - High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. - If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. 1. Turn the ignition switch ON (II), but do not start the engine. 2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 3. Make sure the HDS communicates with the PCM and other vehicle systems.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3190 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3191 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3200 2.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3208 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3209 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3210 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3211 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3212 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3213 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3214 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings.

Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 3216 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

The MICU controls many systems related to the body controller area and a security system, and also works as a gateway to diagnose the other B-CAN connected ECUs with the HDS. Refer to each system circuit diagram for details. The MICU also controls the function of these circuits: - Entry lights control (map lights and ceiling light) - Exterior lights control (including the daytime running lights control) - Horn - Interlock system - Key-in reminder - Keyless entry - Lights-on reminder - Power door locks - Seat belt reminder - Security alarm - Turn signal/hazard warning - Wiper/washer Body Controller Area Network (B-CAN) and Fast Controller Area Network (F-CAN) The body controller area network (B-CAN) and the fast controller area network (F-CAN) share information between multiple electronic control units (ECUs). B-CAN communication moves at a slower speed (33.33 kbps) for convenience related items and for other functions. F-CAN information moves at a faster speed (500 kbps) for "real time" functions such as fuel and emissions data. To allow both systems to share information, the gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN. - The single wire method is used between the units not requiring the communication to move at a fast speed. - Using a single wire method reduces the number of the wires used on the body controller area network. Gateway Function Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3225 The gauge control module (tach) acts as a gateway to allow both systems to share information, the gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN. Network "Loss of Communication" Error Checking Function The ECUs on the CAN circuit send messages to each other. If there are any malfunctions on the network, the odo/trip display on the gauge control module can indicate the error messages by entering the gauge self-diagnostic function. NOTE: For further information about Error indication, refer to the gauge control module self-diagnostic function. Self-diagnostic Function By connecting the HDS to the data link connector (DLC), the HDS can retrieve the diagnostic results from the MICU via a diagnostic line called K-LINE. The K-LINE is distinguished from the CAN line, and connected to the CAN related ECUs. The MICU is a gateway between the HDS and B-CAN related ECUs, and sends B-CAN diagnostic results to the HDS. When performing a function test with the HDS, the HDS sends an output signal through the K-LINE to the MICU. The MICU either relays the request to another ECU, or commands the function its self. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3226 Wake-up and Sleep Function The multiplex integrated control system has "wake-up" and "sleep" functions to decrease parasitic draw on the battery when the ignition switch is OFF. - In the sleep mode, the MICU stops functioning (communication and CPU control) when it is not necessary for the system to operate. - As soon as any operation is requested (for example, a door is unlocked), the related control unit in the sleep mode immediately wakes up and begins to function. - When the ignition switch is turned OFF, and the driver's door is opened, then closed, there is a delay about 40 seconds before the control unit goes from the wake-up mode to the sleep mode. - The sleep mode will not function if any door is opened or if a key is in the ignition. - The draw is reduced from 200 mA to less than 35 mA when in the sleep mode. NOTE: For Sleep and Wake-up Mode Test, refer to Information Bus/Testing and Inspection/Component Tests and General Diagnostics. Fail-safe Function To prevent improper operation, the MICU has a fail-safe function. In the fail-safe mode, the output signal is fixed when any part of the system malfunctions (for example, a faulty control unit or communication line). Each control unit has a hardware fail-safe function that fixes the output signal when there is a CPU malfunction, and a software fail-safe function that ignores the signal from a malfunctioning control unit, which allows the system to operate normally. Hardware Fail-safe Control Fail-safe function When a CPU problem or a abnormal power supply voltage is detected, the MICU moves to the hardware fail-safe mode, and each system output load is set to the pre-programmed fail-safe value. Software Fail-safe Control When any of the data from the B-CAN circuit cannot be received within a specified time, or an unusual combination of the data is recognized, the MICU Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3227 moves to the software fail-safe mode. The data that cannot be received is forced to a pre-programmed value. Fuel Fill Door Operation Power Supply Voltage Monitoring Function The MICU monitors the power supply voltage (back-up voltage). If the voltage goes below 10 V, the MICU sends a MICU message and will not store DTCs. Entry Lights Control System The MICU controls the ceiling light ON/OFF and dimming based upon the input signals from each switch. lighting system (Headlights, Parking Lights, Side Marker Lights, License Plate Lights, and Taillights) The MICU contains the relay circuits of the headlight high/low beam and taillights, and controls the lighting system ON/OFF based upon the input signals from the combination light switch. Daytime Running Lights The MICU controls the exterior lights as a daytime running lights based upon the input signals from the each switch. Turn Signal/Hazard Warning The MICU controls the turn signal/hazard warning based upon the input signals from the turn signal and hazard warning switches. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3228 Power Door Locks (Vehicle Speed Sense) The MICU controls the door lock actuators based upon the B-CAN and input signals. Power Door Locks (Normally LOCK/UNLOCK Operation) The MICU controls the door lock actuators based upon the input signals of each switch. Door Lock Response Operation The MICU controls the door lock actuators based upon the B-CAN signals. Power Window Key-off Operation The MICU controls the power windows key-off operation based upon the input signals. Keyless Entry System The MICU controls the door lock actuators based upon the input signals of each switch and the B-CAN signals. Keyless PANIC The MICU controls the keyless PANIC based upon the B-CAN signals. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3229 Security Alarm System The MICU controls the lighting system and horn based upon the input signals of each switch and the B-CAN signals. Key-in Reminder The MICU controls the door lock actuators based upon the IG1, the driver's door switch, and the driver's door lock knob switch signals. Key Interlock (A/T) The MICU controls the key interlock solenoid based upon the IG1, the transmission range switch, and the park-pin switch signals. Answer Back Response Operation The MICU controls the lighting system and horn based upon the B-CAN signals. Wiper/Washer The MICU controls the wiper motor and the washer motor based upon the IG1 and the wiper/washer switch signals. Collision Detection Signal (CDS) Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3230 The MICU controls the door lock actuators based upon the IG1 and the B-CAN signals. HDS Inputs and Commands Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List. This should give the HDS time to update the signal on the Data List. Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not supported. Make sure that the most current software is loaded. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3231 Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Description and Operation > System Description > Page 3232 Information Bus: Description and Operation Circuit Description How the Circuit Works The multiplex integrated control system sends digital signals between control units through shared wires to reduce the number of wires in order to make harnesses lighter. The input signals from each switch are converted to digital signals within the receiving control unit. The digital signals are sent from one control unit to another as serial data over dedicated communication lines. When the appropriate control unit receives the digital signal, it converts the signal back to an operational command, such as operating a relay. The multiplex integrated control system schematic shows its power, grounds, and communication lines. The ceiling light is shown because it is used to blink DTC's when the system is in the self-diagnostic mode. There are two different networks within the multiplex integrated control system: - Body Controller Area Network (B-CAN) - Fast Controller Area Network (F-CAN) The body controller area network (B-CAN) and fast controller area network (F-CAN) share information between multiple electronic control units and work together to form the multiplex integrated control system. The gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN to allow the networks to share information. B-CAN Network B-CAN information is transmitted across the communication lines at a slower speed for convenience related operations that do not require a high process speed. The following systems are related to the B-CAN network: - Entry Light Control System - Exterior Lights - Gauges and Indicators - Horn - Interior Lights - Interlock System (A/T) - Moonroof (EX, Si) - Power Door Locks/Keyless Entry/Security System - Power Windows (LX, EX, Si) - Reminder Systems - Safety Indicator - Wiper/washer F-CAN Network F-CAN information is transmitted across the communication lines at a faster speed for "real time" functions such as fuel, emissions, and traction control data. The following control units operate on the F-CAN network: - ABS Modulator-Control Unit (except '07 Si) - ECM/PCM - EPS Control Unit (Si) - Gauge Control Module (Tach) - SRS Unit - VSA Modulator-Control Unit ('07 Si) Since messages on the F-CAN network are typically of higher importance, a second wire is used for communication circuit integrity monitoring.

If any fuse is blown, replace it and go to step 3. 3. Disconnect under-dash fuse/relay box connectors E, F, G, K, and T. NOTE: All connector views are wire side of female terminals. 4. Inspect the connector and socket terminals to be sure they are all making good contact. - If the terminals are bent, loose or corroded, repair them as necessary and recheck the system. - If the terminals look OK, go to step 5. 5. With the connector still disconnected, make these input tests at the appropriate connector. - If any test indicates a problem, find and correct the cause, then recheck the system. - If all the input tests prove OK, go to step 6. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 3239 6. Reconnect the connectors to the under-dash fuse/relay box, and make these input tests at the connectors. - If any test indicates a problem, find and correct the cause, then recheck the system. - If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box. Sleep and Wake-Up Mode Test Sleep and Wake-up Mode Test 1. Shift to the sleep mode: Turn the ignition switch OFF, combination lights switch OFF, and interior lights OFF. If the MICU receives no signals from the inputs listed, it will go into sleep mode in less than 40 seconds. 2. Confirm the sleep mode: Measure the voltage on the B-CAN communication line (PNK wires); there should be battery voltage in the sleep mode. Check the parasitic draw at the battery while shifting into the sleep mode; amperage should change from about 200 mA to less than 35 mA. 3. Shift to the wake up mode: When the ignition switch is turned ON (II), the MICU, gauge control module, immobilizer-keyless control unit-receiver, and PCM wake up at the same time without "talking" to each other through the communication lines. When any switch in the multiplex integrated control system is turned on, it wakes up its related control unit which, in turn, wakes up the other units. After confirming the sleep mode, look in the following table for the switch most related to the problem. Operate that switch and see if its control unit wakes up. NOTE: If any control unit is faulty and will not wake up, several circuits in the system will malfunction at the same time. In the table, the control unit is followed by a list of the switches and input signals that can wake it up.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Malfunction Indicator Lamp > Component Information > Description and Operation Malfunction Indicator Lamp: Description and Operation Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness Codes) The vehicle has certain "readiness codes" that are part of the on-board diagnostics for the emissions systems. If the vehicle's battery has been disconnected or gone dead, if the DTCs have been cleared, or if the PCM has been reset, these codes are reset. In some states, part of the emissions testing is to make sure these codes are set to complete. If all of them are not set to complete, the vehicle may fail the test, or the test cannot be finished. To check if the readiness codes are set to complete, turn the ignition switch ON (II), but do not start the engine. The MIL will come on for 15-20 seconds. If it then goes off, the readiness codes are complete'. If it flashes five times, one or more readiness codes are not complete. To set each code, drive the vehicle or run the engine as described in the procedures.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3358 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3359 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3376 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3377 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3378 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3379 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3380 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3381 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity.

To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3383 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda 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 3384 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Stored data based on failed parts should be cleared by using the CLEAR COMMAND of the HDS, if parts are replaced. The HDS has three kinds of clear commands to meet this purpose. They are DTC clear, PCM reset, and CKP pattern clear. DTC clear command erases all stored DTC codes, freeze data, on-board snapshot, and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting. The PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all specific data to correct the system except CKP pattern. If the CKP pattern data in the PCM was cleared, you must do the CKP pattern learn procedure. The CKP pattern clear command erases only CKP pattern data. This command is for repair of a misfire or the CKP sensor. Scan Tool Clear Command If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the PCM, and it clears all commands at the same time (CKP pattern learn, idle learn, readiness codes, freeze data, on-board snapshot, and DTCs). After you clear all commands, you then need to do these procedures, in this order: PCM idle learn procedure.; CKP pattern learn procedure; Test-drive to set readiness codes to complete . DTC Clear 1. Clear the DTC with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. PCM Reset NOTE:If the low fuel indicator is blinking, the PCM can not be reset with the HDS. To reset the PCM, do the low fuel indicator troubleshooting . 1. Reset the PCM with the HDS while the engine is stopped. 2. Turn the ignition switch OFF. 3. Turn the ignition switch ON (II), and wait 30 seconds. 4. Turn the ignition switch OFF, and disconnect the HDS from the DLC. 5. Do the PCM idle learn procedure, CKP Pattern Clear/CKP Pattern Learn Clear/Learn Procedure (with the HDS) 1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 2. Turn the ignition switch ON (II). 3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See: Testing and Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting 4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS. 5. Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Engine Control Module > Component Information > Service and Repair > Procedures > Page 3423 Learn Procedure (without the HDS) 1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on. 2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the transmission in 2 position. 3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm down to 3,000 rpm with the transmission in 2 position. 4. Repeat step 2 and 3 several times. 5. Turn the ignition switch OFF. 6. Turn the ignition switch ON (II), and wait 30 seconds. How to End a Troubleshooting Session (required after any troubleshooting) 1. Reset the PCM with the HDS. 2. Do the PCM idle learn procedure. 3. Turn the ignition switch OFF. 4. Disconnect the HDS from the DLC. NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the HDS. Updating the ECM/PCM Updating the PCM Special Tools Required - Honda diagnostic system (HDS) tablet tester - Honda interface module (HIM) and an iN workstation with HDS and CM update software - HDS pocket tester - GNA600 and an iN workstation with HDS and CM update software Use any one of these update tools. NOTE: Use this procedure when you need to update the PCM during a troubleshooting procedures. - Make sure the HDS/HIM has the latest software version. - Before you update the PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. - Never turn the ignition switch OFF during the update. If there is a problem with the update, leave the ignition switch ON. - To prevent PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update. - To ensure the latest program is installed, do PCM update whenever the PCM is substituted or replaced. - You cannot update PCM with a program it already has. It will only accept a new program. - High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. - If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. 1. Turn the ignition switch ON (II), but do not start the engine. 2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard. 3. Make sure the HDS communicates with the PCM and other vehicle systems.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3601 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3602 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3609 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3619 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3620 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3621 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3622 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3623 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3624 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3625 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3626 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Computers and Control Systems > Variable Valve Timing Actuator > Component Information > Diagrams > Diagram Information and Instructions > Page 3627 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

(Cam angle is changed to obtain the desired EGR effect and reduce pumping loss). Operation At engine start, and high load - The rocker arm oil control valve is OFF. - Oil pressure enters secondary rocker arm B from the oil passage in the intake rocker shaft. This forces the VTEC switching piston into secondary rocker arm A against the return spring and disengages secondary arm A from secondary arm B to stop valve actuation. At cruise The rocker arm oil control valve switches oil pressure to the oil passage in the intake rocker arm shaft. Oil pressure then enters secondary rocker arm A, and it moves the VTEC switching piston in the rocker arm. This causes the VTEC switching piston to slide into secondary rocker arm B, locking secondary rocker arms A and B together.

This bracket protects the fuel hose quick connect fitting from damage during a crash. On 128 vehicles, the nut for the fuel feed hose bracket is missing. In the event of a crash, the bracket may become loose, which could damage the quick connect fitting. A damaged quick connect fitting could lead to a fuel leak, increasing the risk of a fire. VEHICLES AFFECTED The 128 affected vehicles were built in Canada (VINs beginning with 2HG), between late August and early September 2008. To verify vehicle eligibility, you must do a VIN status inquiry. If you re working on a customer vehicle, also make sure the customer has a notification letter. To see if a vehicle has already had this campaign completed, check for a punch mark below the first character of the engine compartment VIN. Some vehicles affected by this campaign may be in your new vehicle inventory. You should not sell or lease these vehicles until they have been repaired. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling or leasing it. Should an unrepaired vehicle cause an injury or damage because of the recalled item, the dealership will be solely responsible to the damaged party, and will be required to defend and indemnify American Honda for any resulting claims. CUSTOMER NOTIFICATION Owners of affected vehicles will receive a notification of this campaign the week of October 13, 2008. An example of the customer notification is shown in this service bulletin.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3877 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3878 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3885 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3895 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3896 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3897 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3898 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3899 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3900 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3901 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3902 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Tank Unit > Component Information > Diagrams > Diagram Information and Instructions > Page 3903 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4100 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4101 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4118 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4119 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4120 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4123 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4124 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4125 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 4126 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4191 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4209 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4210 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4211 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4214 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity.

To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4216 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Powertrain Management > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4217 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4492 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4510 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4511 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4512 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4513 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4514 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4515 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4516 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4517 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Lamps and Indicators A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4518 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

If the TP POSITION CHECK failed in step 5, clean the throttle body. 9. Do the PCM idle learn procedure. 10. Do the crank (CKP) learn procedure. How to Substitute the PCM Substituting the PCM Special Tools Required ^ Honda diagnostic system (HDS) tablet tester ^ Honda interface module (HIM) and an iN workstation with HDS and CM update software ^ HDS pocket tester ^ GNA600 and an iN workstation with HDS and CM update software Use this procedure when you need to substitute a known-good PCM during troubleshooting procedures. 1. Make sure you have the anti-theft code for the audio system or the navigation system (if equipped), then write down the audio presets. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Turn the ignition switch to ON (II). 4. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting. If you did the DLC circuit troubleshooting, skip steps 5 thru 9, then clean the throttle body after substituting the PCM. 5. Select the INSPECTION MENU with the HDS. 6. Select the TP POSITION CHECK in the ETCS TEST with the HDS. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 7. Turn the ignition switch to LOCK (0). 8. Remove the battery. 9. Remove the PCM cover (A). 10. Remove the bolts (D), and remove the PCM (E).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Cooler, A/T > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Equipment Information Transmission Cooler: Technical Service Bulletins A/T - Cooler Flushing Equipment Information 89-022 May 16, 2008 Applies To: Vehicles With an In-Radiator ATF Cooler - ALL ATF Cooler Cleaner (Supersedes 89-022, dated June 18, 2004, to update the information marked by asterisks) Before installing an overhauled or remanufactured A/T, you must thoroughly clean the ATF cooler to prevent system contamination. Failure to do so could cause a repeat A/T failure. The ATF Cooler Cleaner (PIN GTHTTCF6H) is a portable, electrically operated special tool that cleans the ATF cooler with high- pressure, heated ATF. This cleaning action melts down waxy varnish residue left by burnt ATF and purges metal particles, clutch material, and other contaminants. The ATF Cooler Cleaner has these features: ^ Quick-connect fittings and color-coded hoses for easy hookup. ^ Uses about 9.5 gallons of Honda ATF-Z1, which gets filtered and recirculated. ^ Heats ATF to a temperature of 1400 to 150°F and then pumps it through the ATF cooler at high pressure (100 psi) using a pulsating action and air purging. Switching the hoses cleans the ATF cooler in the reverse direction. ^ Two magnetic nonbypass spin-on filters to trap purged contaminants. ^ Built-in tool tray. This service bulletin gives you information for ordering and servicing this special tool, and guides you through the entire ATF cooler cleaning process. *REQUIRED MATERIALS Honda ATF-Z1: P/N 08200-9001 Magnetic Nonbypass Spin-On Filter: T/N GTHNBP12 (12-pack) T/N GTHNBP2 (6-pack) T/N GTHGNBP22 (2-pack) ORDERING INFORMATION Additional ATF cooler cleaners or magnetic nonbypass spin-on filters can be ordered through the Honda Tool and Equipment Program. To order on the iN, click on SERVICE, then Service Bay, then Tool and Equipment Program. From the Tool and Equipment Program menu, click on the Online Catalog tab, and then search for the desired filter pack by part number.* Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Cooler, A/T > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Equipment Information > Page 4658 TOOL DESCRIPTION CLEANING PROCEDURE The cleaning procedure involves hot fluid under high pressure. Check the security of all hoses and connections. Always wear safety glasses or a face shield, gloves, and protective clothing. If you get ATF in your eyes or on your skin, rinse with water immediately. Improper use of the ATF cooler cleaner can result in burns and other serious injuries. Always wear eye protection and protective clothing, and follow all instructions in this bulletin. 1. Plug the ATF cooler cleaner into a 110 V grounded electrical outlet. NOTICE Make sure the outlet has no other appliances (light fixtures, drop lights, extension cords) plugged into it. Also, never plug the cooler cleaner into an extension cord or drop light cord; you would damage the unit. 2. Flip the HEAT toggle switch to ON. Wait 1 hour for the cooler cleaner to reach its operating temperature. (The cooler cleaner is ready to use when the temperature gauge reads 140° to 150°F.)

Connect the appropriate fittings to the ATF cooler inlet and outlet lines. Connect the red hose to the cooler outlet line (the line going to the external filter). Connect the blue hose to the cooler inlet line. 4. Connect a shop air hose to the air purge valve. NOTICE The quick connect fitting has a one-way check valve to keep ATF from entering your shop's air system. Do not remove or replace the fitting. Attach the coupler provided with the cooler cleaner to your shop air line if your coupler is not compatible. 5. Flip the MOTOR toggle switch to ON, and let the pump run for 5 minutes. While the pump is running, open and close the air purge valve periodically to cause agitation and improve the cleaning process. 6. Flip the MOTOR toggle switch to OFF with the air purge valve open. Leave the air purge valve open for at least 15 seconds to purge the lines of residual ATF. 7. Disconnect the red and blue hoses from the ATF cooler, then connect the red hose to the cooler inlet line. 8. Connect the blue hose to the cooler outlet line. 9. Flip the MOTOR toggle switch to ON, and let the pump run for 5 minutes. While the pump is running, open and close the air purge valve periodically. 10. Flip the MOTOR toggle switch to OFF with the air purge valve open. Leave the air purge valve open for at least 15 seconds to purge the lines of residual ATF. 11. Disconnect the red and blue hoses from the ATF cooler lines. Connect the red and blue hoses to each other. 12. Disconnect the shop air from the air purge valve. Disconnect and stow the coupler if used. 13. Disconnect and stow the fittings from the ATF cooler inlet and outlet lines. 14. Unplug the cooler cleaner from the 110 V outlet. TOOL MAINTENANCE Follow these instructions to keep the ATF cooler cleaner working properly: *^ Replace the two magnetic nonbypass spin-on filters every 20 hours, based on hour meter reading. For more information on filter replacement, see the January 2008 Honda ServiceNews article, Hour Meter Tells You When to Replace ATF Cooler Cleaner Filters.* ^ Fill the tank so the ATF is 4.5 inches from the top of the filler hole; do not overfill. NOTE: If the fluid level is low, the red indicator above the HEAT toggle switch comes on and the tank heater will not work. ^ Replace the ATF in the tank when it looks dark or dirty.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Continuously Variable Transmission/Transaxle, CVT > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Equipment Information Continuously Variable Transmission/Transaxle: Technical Service Bulletins A/T - Cooler Flushing Equipment Information 89-022 May 16, 2008 Applies To: Vehicles With an In-Radiator ATF Cooler - ALL ATF Cooler Cleaner (Supersedes 89-022, dated June 18, 2004, to update the information marked by asterisks) Before installing an overhauled or remanufactured A/T, you must thoroughly clean the ATF cooler to prevent system contamination. Failure to do so could cause a repeat A/T failure. The ATF Cooler Cleaner (PIN GTHTTCF6H) is a portable, electrically operated special tool that cleans the ATF cooler with high- pressure, heated ATF. This cleaning action melts down waxy varnish residue left by burnt ATF and purges metal particles, clutch material, and other contaminants. The ATF Cooler Cleaner has these features: ^ Quick-connect fittings and color-coded hoses for easy hookup. ^ Uses about 9.5 gallons of Honda ATF-Z1, which gets filtered and recirculated. ^ Heats ATF to a temperature of 1400 to 150°F and then pumps it through the ATF cooler at high pressure (100 psi) using a pulsating action and air purging. Switching the hoses cleans the ATF cooler in the reverse direction. ^ Two magnetic nonbypass spin-on filters to trap purged contaminants. ^ Built-in tool tray. This service bulletin gives you information for ordering and servicing this special tool, and guides you through the entire ATF cooler cleaning process. *REQUIRED MATERIALS Honda ATF-Z1: P/N 08200-9001 Magnetic Nonbypass Spin-On Filter: T/N GTHNBP12 (12-pack) T/N GTHNBP2 (6-pack) T/N GTHGNBP22 (2-pack) ORDERING INFORMATION Additional ATF cooler cleaners or magnetic nonbypass spin-on filters can be ordered through the Honda Tool and Equipment Program. To order on the iN, click on SERVICE, then Service Bay, then Tool and Equipment Program. From the Tool and Equipment Program menu, click on the Online Catalog tab, and then search for the desired filter pack by part number.* Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Continuously Variable Transmission/Transaxle, CVT > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Equipment Information > Page 4741 TOOL DESCRIPTION CLEANING PROCEDURE The cleaning procedure involves hot fluid under high pressure. Check the security of all hoses and connections. Always wear safety glasses or a face shield, gloves, and protective clothing. If you get ATF in your eyes or on your skin, rinse with water immediately. Improper use of the ATF cooler cleaner can result in burns and other serious injuries. Always wear eye protection and protective clothing, and follow all instructions in this bulletin. 1. Plug the ATF cooler cleaner into a 110 V grounded electrical outlet. NOTICE Make sure the outlet has no other appliances (light fixtures, drop lights, extension cords) plugged into it. Also, never plug the cooler cleaner into an extension cord or drop light cord; you would damage the unit. 2. Flip the HEAT toggle switch to ON. Wait 1 hour for the cooler cleaner to reach its operating temperature. (The cooler cleaner is ready to use when the temperature gauge reads 140° to 150°F.) Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Continuously Variable Transmission/Transaxle, CVT > Component Information > Technical Service Bulletins > A/T - Cooler Flushing Equipment Information > Page 4742 3. Connect the appropriate fittings to the ATF cooler inlet and outlet lines. Connect the red hose to the cooler outlet line (the line going to the external filter). Connect the blue hose to the cooler inlet line. 4. Connect a shop air hose to the air purge valve. NOTICE The quick connect fitting has a one-way check valve to keep ATF from entering your shop's air system. Do not remove or replace the fitting. Attach the coupler provided with the cooler cleaner to your shop air line if your coupler is not compatible. 5. Flip the MOTOR toggle switch to ON, and let the pump run for 5 minutes. While the pump is running, open and close the air purge valve periodically to cause agitation and improve the cleaning process. 6. Flip the MOTOR toggle switch to OFF with the air purge valve open. Leave the air purge valve open for at least 15 seconds to purge the lines of residual ATF. 7. Disconnect the red and blue hoses from the ATF cooler, then connect the red hose to the cooler inlet line. 8. Connect the blue hose to the cooler outlet line. 9. Flip the MOTOR toggle switch to ON, and let the pump run for 5 minutes. While the pump is running, open and close the air purge valve periodically. 10. Flip the MOTOR toggle switch to OFF with the air purge valve open. Leave the air purge valve open for at least 15 seconds to purge the lines of residual ATF. 11. Disconnect the red and blue hoses from the ATF cooler lines. Connect the red and blue hoses to each other. 12. Disconnect the shop air from the air purge valve. Disconnect and stow the coupler if used. 13. Disconnect and stow the fittings from the ATF cooler inlet and outlet lines. 14. Unplug the cooler cleaner from the 110 V outlet. TOOL MAINTENANCE Follow these instructions to keep the ATF cooler cleaner working properly: *^ Replace the two magnetic nonbypass spin-on filters every 20 hours, based on hour meter reading. For more information on filter replacement, see the January 2008 Honda ServiceNews article, Hour Meter Tells You When to Replace ATF Cooler Cleaner Filters.* ^ Fill the tank so the ATF is 4.5 inches from the top of the filler hole; do not overfill. NOTE: If the fluid level is low, the red indicator above the HEAT toggle switch comes on and the tank heater will not work. ^ Replace the ATF in the tank when it looks dark or dirty.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4822 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4840 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4841 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4842 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4844 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Lamps and Indicators - Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4845 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity.

To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings.

Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end.

If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

If the TP POSITION CHECK failed in step 5, clean the throttle body. 9. Do the PCM idle learn procedure. 10. Do the crank (CKP) learn procedure. How to Substitute the PCM Substituting the PCM Special Tools Required ^ Honda diagnostic system (HDS) tablet tester ^ Honda interface module (HIM) and an iN workstation with HDS and CM update software ^ HDS pocket tester ^ GNA600 and an iN workstation with HDS and CM update software Use this procedure when you need to substitute a known-good PCM during troubleshooting procedures. 1. Make sure you have the anti-theft code for the audio system or the navigation system (if equipped), then write down the audio presets. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Turn the ignition switch to ON (II). 4. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting. If you did the DLC circuit troubleshooting, skip steps 5 thru 9, then clean the throttle body after substituting the PCM. 5. Select the INSPECTION MENU with the HDS. 6. Select the TP POSITION CHECK in the ETCS TEST with the HDS. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 7. Turn the ignition switch to LOCK (0). 8. Remove the battery. 9. Remove the PCM cover (A). 10. Remove the bolts (D), and remove the PCM (E).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK.

Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 4999 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5000 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5001 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5003 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5004 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5005 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5006 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Lamps and Indicators Transmission and Drivetrain > Lamps and Indicators - A/T > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5007 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

It will only accept a new program. ^ Before you update the PCM, make sure the battery is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. ^ Never turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged. ^ To prevent PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moon roof (if equipped), door locks, etc.) during the update. ^ If you need to diagnose the Honda interface module (HIM) because the HIM's red 3) light came on or was flashing during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage. ^ High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. 1. Turn the ignition switch to ON (II), but do not start the engine. 2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover. 3. Make sure the HDS communicates with the PCM. if it does not, go to the DLC circuit troubleshooting. 4. Select the INSPECTION MENU with the HDS. 5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure. 6. Exit the HDS, then select the CM update, and follow the screen prompts to update the PCM. 7. If the PCM has the latest software, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update procedure requires you to cool the PCM, follow the screen prompts. If you run into a problem (programming takes over 15 minutes, status bar goes over 100 D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, follow these steps to minimize the chance of damaging the PCM: ^ Leave the ignition switch in the "ON (II)" position. ^ Connect a jumper battery (do not connect a battery charger). ^ Shut down the HDS. ^ Disconnect the HDS from the DLC. ^ Reboot the HDS. ^ Reconnect the HDS to the DLC, and try the update procedure again.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5143 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5144 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5153 2.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5161 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5162 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5163 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5164 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5165 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5166 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5167 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5168 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 5169 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information Brake Rotor/Disc: Technical Service Bulletins Brakes - Brake Disc Refinishing Information 00-088 July 14, 2010 Applies To: ALL Models Brake Disc Refinishing Guidelines (Supersedes 00-088, dated October 6, 2006, to revise the information marked with the black bars) *REVISION SUMMARY The requirement to refinish new brake discs was removed.* American Honda does not allow replacement of brake discs under warranty unless the brake disc is beyond its service limit for refinishing. If the brake disc is within its service limit, you must refinish it. Maximum refinishing limits may be found in the Conventional Brakes section of the appropriate service manual. *Refinish brake discs only when they are scored or out of specification for runout or parallelism. See the appropriate service manual for the specifications.* American Honda requires refinishing of the front brake discs with an on-car brake lathe that mounts to the steering knuckle. Use of an on-car, steering knuckle- mounted lathe is critical because it corrects runout of the hub and disc as an assembly. Experience has shown that very small amounts of runout, not felt as brake pulsation initially, will grow and become noticeable as the discs are subjected to heat and wear over time and mileage. Two on-car brake lathes are recommended. The Kwik-Lathe, model number KWY-108000501, is supported with automatic shipments of adapters for new models, when required. The Accu-turn On-car Brake Lathe, model ACCHONOCLPKG, is also recommended. A power driver is required for the 82000 and is highly recommended for all other models. The Kwik-Lathe power driver model number is KWY-108012005; the Accu-turn lathe includes a power driver. Here are some advantages of using power drivers: ^ The disc is rotated at the optimum speed for a smooth and consistent cut. ^ There is no need to climb in and out of the vehicle to start and stop the engine or to shift the transmission. ^ Securing the opposite wheel with a tie-down strap is not required. ^ There is no waiting for the engine to return to idle and no concern about engine speed changes that can adversely affect brake disc cut and finish. ^ The Traction Control System (TCS) is not involved. ^ Consistent cutting speed increases cutting tool life. ORDERING INFORMATION Order brake lathes and power drivers through the Honda Tool and Equipment Program. To place an order, call or use the fax order form provided in your Honda Tool and Equipment Program Catalog. Phone lines are open Monday thru Friday from 7:30 a.m. to 7:00 p.m. Central Time. You can also order online through the Interactive Network (iN). Click on Service, Tool and Equipment, and then Online Catalog. Click on Alignment, Wheel, and Brake Equipment, and then On-Car Brake Lathes. WARRANTY CLAIM INFORMATION None, this bulletin is for information only. FRONT BRAKE DISCS The following guidelines show the Kwik-Way lathe setup, the Accu-turn lathe setup is similar. Setting Up the Vehicle Put the transmission in Neutral. If you are not using the power drive system, start the engine, and let it warm up to its normal operating temperature so the idle speed will stabilize to its lowest rpm. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information > Page 5191 Raise the vehicle on a lift. Check for loose wheel bearings. You must replace loose wheel bearings before you refinish the brake discs. If you do not, the brake lathe will not correct for brake disc runout, resulting in an uneven finish and brake pulsation. Remove the front wheels, then reinstall the wheel nuts with flat washers to compensate for the removed wheel. Torque the wheel nuts to the required specification (see the appropriate service manual). Remove the caliper assembly. Use a wire or a S-hook to hold the caliper to the spring or damper tower. Do not kink the brake hose or use it to support the caliper. If you are not using the power drive system and the vehicle has ICS or VSA, make sure you install a brake pad spreader between the pads on the hanging caliper. Also, make sure the ICS or VSA is turned off anytime the engine is started. If the system is not turned off, the brakes could activate, causing the brake pads on the hanging caliper to hit each other or the caliper pistons to fall out. Install the vibration damper on the brake disc. If you are not using the power drive system, make sure you install the protective band around the wheel nuts. If you are not using the power drive system, use a fabric tie-down strap to secure the brake disc that is opposite to the one you are refinishing. If you are working on a Prelude with ATTS, do not use a tie-down strap; let both wheels turn freely. Mounting the Brake Lathe Remove the tool bed from the brake lathe, then mount the brake lathe to the steering knuckle with a Honda 1-piece speed mount. These mounts provide quicker, more accurate mounting, and can be ordered through the Honda Tool and Equipment Program (see ORDERING INFORMATION). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information > Page 5192 Honda 1-Piece Speed Mounts P/N KWY-108006000 (for most models), P/N KWY-108007500 (Odysseys, Pilots, and Ridgelines with two-piston calipers) Attaching the Power Drive System 1. Make sure the drive motor assembly on the power drive system is level with the brake disc. 2. Attach the mounting yoke to the brake disc, and secure it with one of the wheel nuts. Torque the wheel nut to the required specification (see the appropriate service manual). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information > Page 5193 3. Attach the driveshaft on the drive motor assembly to the mounting yoke, making sure the center line of the driveshaft is level with the spindle nut on the wheel hub. 4. Set the lower toggle switch on the drive motor assembly to FWD (counterclockwise rotation) or REV (clockwise rotation). Setting Up and Adjusting the Brake Lathe Use Kwik-Way cutting bits, P/N KWY-109109223, and the holding screws that come with them. These bits are stamped KW and are available through the Honda Tool and Equipment Program (see ORDERING INFORMATION). Before you use the brake lathe, inspect the tips of the cutting bits with a magnifying glass to make sure the tips are not worn out. Each bit has three tips. If a tip is worn, rotate the bit, and use a new tip. A worn tip produces a poor finish and may cause chattering. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information > Page 5194 Reinstall the tool bed on the brake lathe with the top of the cutting bits facing up and the feed knobs facing down. Adjust the tool bed until the brake disc is centered between the cutting bits. For proper refinishing, the brake disc must turn toward the top of the cutting bits. Do not set the cutting depth on the brake lathe to more than 0.2 mm (0.008 in.). This is two divisions on the cutting knob. Make sure you start your cut at least 3 mm (0.12 in.) beyond the worn area on the brake disc. If you are cutting larger diameter brake discs, make sure you use the 150 cutting bit holders. These bit holders, available through the Honda Tool and Equipment Program (see ORDERING INFORMATION), supersede the original bit holders and provide better cutting coverage for larger diameter brake discs. Each bit holder is clearly marked for proper installation on the tool holder. Cutting the Brake Disc To get the smoothest cut and the best brake disc finish, always use the slowest feed speed on the tool bed feed motor. Place the drive belt on the smallest pulley of the feed motor and on the largest pulley of the hand wheel. Make sure the lower toggle switch on the power drive system drive motor assembly is set to the proper rotation to turn the brake disc toward the top of the cutting bits. Plug the tool bed feed motor into the power outlet on the drive motor assembly, then turn on the drive motor with the upper toggle switch on the assembly. If you are not using the power drive system, make sure the transmission is in 1st gear (2nd gear on Preludes with ATTS) or Reverse and the engine is idling, but not at a fast idle. If the transmission and engine are at higher gears and speeds, you will damage the cutting bits. Turn on the tool bed feed motor, and snap it into place; there should be tension on the feed belt. Cut the brake disc until the cutting bits clear the outer edge of the disc. The cutting bits should produce a smooth, consistent finish with no chatter marks or grooves. If the disc did not clean up entirely on the first pass, reset the brake lathe and make a second pass. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Technical Service Bulletins > Brakes - Brake Disc Refinishing Information > Page 5195 Finishing the Job Remove the vibration damper and the protective band (if used). Use a micrometer to measure the thickness of the brake disc. Make sure the thickness is within the service manual specifications. Clean the brake disc with soapy water or brake cleaner, then wipe it dry. Use a vacuum cleaner to remove any dust or chips, but do not use compressed air. Unplug the tool bed feed motor from the drive motor assembly, and remove the mounting yoke from the brake disc. Remove the speed mount from the steering knuckle. Apply a small amount of Molykote 77 grease to the brake pad shims. Reinstall the caliper assembly. (If you did not use the power drive system, use the brake pad spreader to push the pistons back into the caliper.) Torque the nuts and bolts to the required specification (see the appropriate service manual). Refinish the other front brake disc using the same guidelines. Check the brake fluid level, then test-drive the vehicle to make sure the brake pedal is firm and does not pulsate. Lightly apply the brakes about 20 times during the test-drive to seat the brake pads. REAR BRAKE DISCS It is possible to use an on-car lathe on some models if the rear caliper mounts are low enough to clear the vehicle body. A power driver is needed for front drive models. Refinish rear brake discs on bench-mounted equipment if necessary. Follow the same guidelines you used for refinishing front brake discs, noting these differences: ^ Mount the brake lathe to the rear knuckle with the Honda 2-Piece Adapter (P/N KWY-1 08102504). You can order the 2-piece adapter through the Honda Tool and Equipment Program (see ORDERING INFORMATION).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5355 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5356 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5373 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5374 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5375 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5376 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5377 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5378 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5379 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5380 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Sensors and Switches - Starting and Charging > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5381 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Technical Service Bulletins > Charging System - Revised Alternator Testing Alternator: Technical Service Bulletins Charging System - Revised Alternator Testing 10-054 September 8, 2010 Applies To: 2005-10 Models - ALL Service Manual Update: Alternator Testing BACKGROUND American Honda is currently developing new equipment and procedures for testing alternators and starters. Until this equipment is released, please use the following information. Do not use the ED-18 for testing alternators because it will misjudge the charging system performance on some models, leading to the unnecessary replacement of good parts. To properly test alternators, use one of the following tools: ^ OTC Tester - Includes the following testers: 0TC3130, OTC3130AGM, 0TC3131, and 0TC3131 AGM ^ ARBST ^ VAT40 If you do not have one of these tools, the OTC tester is available through the special tool loan program. For more information about the loan program, refer to S/B 98-051, Special Tool Loan Program. Honda vehicles use an electronic load detection (ELD) circuit in the charging system to reduce fuel consumption. The alternator has two modes; low output and high output. When the vehicle is cruising and there is a light electrical load, the alternator switches to the low output mode that produces about 12.5 V and low amperage. When the vehicle load increases (the customer turns on the headlights, the seat heaters, the rear defroster, etc.), the alternator switches to the high output mode that raises the voltage and amperage. WARRANTY CLAIM INFORMATION None. ALTERNATOR TEST For more information on the OTC tester, refer to its user guide. Besides the one that came with the tool, you can also find the guide online under General Publications, Tool Information. 1. Question the customer about the events that led up to the problem. Many charging system complaints are caused by leaving the headlights or interior lights on, headlight flicker, or installing aftermarket accessories with a high parasitic draw that drains the battery. 2. Visually inspect the battery cables and grounding straps to confirm the connections are clean and tight. If there are any damaged parts or loose connections, repair them as needed. 3. Test the vehicle battery with the GR-8. Refer to S/B 88-023, Battery Testing and Replacement. 4. Connect the OTC tester to the vehicle: ^ Connect the negative (-) heavy load lead to the negative battery terminal. ^ Connect the positive (+) heavy load lead to the positive battery terminal. 5. Calibrate the OTC tester by holding the amp probe away from any conductors, and pressing the ZERO AMPS button. 6. Connect the amp probe to the vehicle's negative battery cable. Make sure the arrow on the probe points toward the vehicle's battery. NOTE: If the vehicle has a second battery negative cable, make sure the probe is around that as well. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Technical Service Bulletins > Charging System - Revised Alternator Testing > Page 5424 7. Enter the number of cylinders on the OTC tester. 8. Start the engine, set the parking brake to turn off the DRL (daytime running lights), and turn off all other electrical accessories. 9. Press the CHARGING SYSTEM TEST button. 10. Raise and hold the engine speed at 2,000 rpm until RUN AT IDLE appears on the display. NOTE: Stand back from the battery, and do not place any objects on top of the OTC tester; it gets hot during testing. 11. Let the engine idle until TEST COMPLETE appears on the display. 12. Press CONTINUE to see the results, and write them down. The first screen lists the REGULATOR VOLTS. Press CONTINUE again to list the PEAK AMPS. 13. Refer to the AMPERAGE LOAD SPECIFICATIONS table, and compare the vehicle results against the listed amperage value. Is the vehicle amperage (PEAK AMPS) equal to or greater than the value listed in the AMPERAGE table? Yes - Go to step 14. No - Replace the alternator, and retest. 14. Check the regulator voltage you wrote down in step 12. ^ If it's between 13.5 and 15.1 V, the alternator is OK. Continue with normal troubleshooting. ^ If it's not between 13.5 and 15.1 V, replace the alternator, and retest. AMPERAGE LOAD SPECIFICATIONS NOTE: The amperage values listed below are used for testing purposes and represent 75% of the alternator's maximum output.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5429 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5430 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5437 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5447 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5448 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5449 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5451 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5452 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5453 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5454 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Diagram Information and Instructions > Page 5455 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Alternator Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Page 5457 Alternator: Description and Operation Alternator Control The alternator signals the PCM during charging. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Page 5458 Alternator: Testing and Inspection Alternator Testing, Update by SMU #10-054 September 8, 2010 Applies To: 2005-10 Models - ALL Service Manual Update: Alternator Testing BACKGROUND American Honda is currently developing new equipment and procedures for testing alternators and starters. Until this equipment is released, please use the following information. Do not use the ED-18 for testing alternators because it will misjudge the charging system performance on some models, leading to the unnecessary replacement of good parts. To properly test alternators, use one of the following tools: ^ OTC Tester - Includes the following testers: 0TC3130, OTC3130AGM, 0TC3131, and 0TC3131 AGM ^ ARBST ^ VAT40 If you do not have one of these tools, the OTC tester is available through the special tool loan program. For more information about the loan program, refer to S/B 98-051, Special Tool Loan Program. Honda vehicles use an electronic load detection (ELD) circuit in the charging system to reduce fuel consumption. The alternator has two modes; low output and high output. When the vehicle is cruising and there is a light electrical load, the alternator switches to the low output mode that produces about 12.5 V and low amperage. When the vehicle load increases (the customer turns on the headlights, the seat heaters, the rear defroster, etc.), the alternator switches to the high output mode that raises the voltage and amperage. WARRANTY CLAIM INFORMATION None. ALTERNATOR TEST For more information on the OTC tester, refer to its user guide. Besides the one that came with the tool, you can also find the guide online under General Publications, Tool Information. 1. Question the customer about the events that led up to the problem. Many charging system complaints are caused by leaving the headlights or interior lights on, headlight flicker, or installing aftermarket accessories with a high parasitic draw that drains the battery. 2. Visually inspect the battery cables and grounding straps to confirm the connections are clean and tight. If there are any damaged parts or loose connections, repair them as needed. 3. Test the vehicle battery with the GR-8. Refer to S/B 88-023, Battery Testing and Replacement. 4. Connect the OTC tester to the vehicle: ^ Connect the negative (-) heavy load lead to the negative battery terminal. ^ Connect the positive (+) heavy load lead to the positive battery terminal. 5. Calibrate the OTC tester by holding the amp probe away from any conductors, and pressing the ZERO AMPS button. 6. Connect the amp probe to the vehicle's negative battery cable. Make sure the arrow on the probe points toward the vehicle's battery. NOTE: If the vehicle has a second battery negative cable, make sure the probe is around that as well. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Charging System > Alternator > Component Information > Diagrams > Page 5459 7. Enter the number of cylinders on the OTC tester. 8. Start the engine, set the parking brake to turn off the DRL (daytime running lights), and turn off all other electrical accessories. 9. Press the CHARGING SYSTEM TEST button. 10. Raise and hold the engine speed at 2,000 rpm until RUN AT IDLE appears on the display. NOTE: Stand back from the battery, and do not place any objects on top of the OTC tester; it gets hot during testing. 11. Let the engine idle until TEST COMPLETE appears on the display. 12. Press CONTINUE to see the results, and write them down. The first screen lists the REGULATOR VOLTS. Press CONTINUE again to list the PEAK AMPS. 13. Refer to the AMPERAGE LOAD SPECIFICATIONS table, and compare the vehicle results against the listed amperage value. Is the vehicle amperage (PEAK AMPS) equal to or greater than the value listed in the AMPERAGE table? Yes - Go to step 14. No - Replace the alternator, and retest. 14. Check the regulator voltage you wrote down in step 12. ^ If it's between 13.5 and 15.1 V, the alternator is OK. Continue with normal troubleshooting. ^ If it's not between 13.5 and 15.1 V, replace the alternator, and retest. AMPERAGE LOAD SPECIFICATIONS NOTE: The amperage values listed below are used for testing purposes and represent 75% of the alternator's maximum output.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5486 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5487 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5504 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5505 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5506 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5507 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5508 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5509 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5510 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5511 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Ignition Switch > Component Information > Diagrams > Diagram Information and Instructions > Page 5512 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Remove the starter. 2. Disassemble the starter as shown at the beginning of this procedure. 3. Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5534 4. Check the commutator (A) surface. If the surface is dirty or burnt, resurface it with an emery cloth or a lathe to the specifications in step 5, or recondition with #500 or #600 sandpaper (B). 5. Check the commutator diameter. If the diameter is below the service limit, replace the armature. 6. Measure the commutator (A) runout. - If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments. - If the commutator runout is not within the service limit, replace the armature. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5535 7. Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica (C) between the commutator segments. The undercut should not be too shallow, too narrow, or V-shaped (D). 8. Check for continuity between the segments of the commutator. If there is open circuit between any of the segments, replace the armature. 9. Place the armature (A) on an armature tester (B). Hold a hacksaw blade (C) on the armature core. If the blade is attracted to the core or vibrates while the core is turned, the armature is shorted. Replace the armature. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5536 10. Check for continuity between the commutator (A) and the armature coil core (B), and between the commutator and the armature shaft (C). If there is continuity, replace the armature. 11. Measure the brush length. If it is not within the service limit, replace the brush holder assembly. Starter Field Winding Test 12. Check for continuity between the brushes (A). If there is no continuity, replace the armature housing (B).

Hold the drive gear (B), and turn the overrunning clutch in the direction shown to make sure it turns freely. Also make sure the overrunning clutch locks in the opposite direction. 18. If the starter drive gear is worn or damaged, replace the overrunning clutch assembly; the gear is not available separately. Check the condition of the flywheel ring gear if the starter drive gear teeth are damaged. Starter Reassembly 19. Pry back each brush spring with a screwdriver, then position the brush about halfway out of its holder. Release the spring to hold it in place. NOTE: To seat new brushes, slip a strip of # 500 or # 600 sandpaper, with the grit side up, between the commutator and each brush, and smoothly turn the armature. The contact surface of the brushes will be sanded to the same contour as the commutator. 20. Install the armature in the housing, and install the brush holder. Next, pry back each brush spring again, and push the brush down until it seats against the commutator, then release the spring against the end of the brush. 21. Install the starter end cover to retain the brush holder.

Remove the starter. 2. Disassemble the starter as shown at the beginning of this procedure. 3. Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5540 4. Check the commutator (A) surface. If the surface is dirty or burnt, resurface it with an emery cloth or a lathe to the specifications in step 5, or recondition with #500 or #600 sandpaper (B). 5. Check the commutator diameter. If the diameter is below the service limit, replace the armature. 6. Measure the commutator (A) runout. - If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments. - If the commutator runout is not within the service limit, replace the armature. 7. Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica (C) between the commutator segments. The undercut should not be too shallow, too narrow, or V-shaped (D). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5541 8. Check for continuity between the segments of the commutator. If there is an open circuit between any of the segments, replace the armature. 9. Place the armature (A) on an armature tester (B), Hold a hacksaw blade (C) on the armature core. If the blade is attracted to the core or vibrates while the core is turned, the armature is shorted. Replace the armature. 10. Check with an ohmmeter for continuity between the commutator (A) and the armature coil core (B), and between the commutator and the armature shaft (C). If there is continuity, replace the armature. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5542 Starter Brush Inspection 11. Measure the brush length. If it is shorter than the service limit, replace the brush holder assembly. Starter Brush Holder Test 12. Check for continuity between the (+) brushes (A) and (-) brushes (B). If there is continuity, replace the brush holder assembly. Planetary Gear Inspection 13. Check the planetary gears (A) and internal ring gear (B). Replace them if they are worn or damaged. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Service and Repair > Removal and Replacement > Page 5543 Overrunning Clutch Inspection 14. While holding the drive gear (A), turn the gear shaft (B) counterclockwise. Check that the drive gear comes out to the other end. If the drive gear does not move smoothly, replace the gear cover assembly. 15. While holding the drive gear, turn the gear shaft clockwise. The gear shaft should turn freely. If the gear shaft does not turn freely, replace the gear cover assembly. 16. If the starter drive gear is worn or damaged, replace the overrunning clutch assembly; the gear is not available separately. Check the condition of the torque converter ring gear to see if the starter drive gear teeth are damaged. Starter Reassembly 17. Install the brush into the brush holder, and set the armature (A) in the brush holder (B). NOTE: To seat the new brushes, slip a strip of # 500 or #600 sandpaper, with the grit side up, between the commutator and each brush, and smoothly turn the armature. The contact surface of the brushes will be sanded to the same contour as the commutator.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5567 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5568 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5577 2.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5585 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5586 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5587 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5588 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5589 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5590 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5591 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5592 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5593 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5620 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5621 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5630 2.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5638 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5639 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5640 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5641 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5642 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5643 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5644 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5645 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5646 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5678 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5679 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5686 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5688 2. Remove the terminal. 3. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE B: 1. Remove the secondary lock from the male terminal half. 2. Remove the secondary lock from the female terminal half.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5696 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5697 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5698 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5699 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5700 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5701 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5702 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5703 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5704 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 5743 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 5744 Multiple Junction Connector: Service and Repair How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Starting and Charging > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 5745 the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun.

Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures.

By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5839 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5840 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5847 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5857 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5858 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5859 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5860 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5861 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5862 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5863 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5864 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 5865 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5892 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5893 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5910 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5911 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5912 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5913 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5914 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5915 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5916 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5917 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse > Component Information > Diagrams > Diagram Information and Instructions > Page 5918 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5950 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5951 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5958 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5968 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape.

Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5970 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5971 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5972 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5973 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5974 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5975 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 5976 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 6015 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 6016 Multiple Junction Connector: Service and Repair How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Power and Ground Distribution > Multiple Junction Connector > Component Information > Service and Repair > How to Replace Connector Terminals > Page 6017 the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material.

Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun.

Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures.

By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit.

BACKGROUND New tools were developed to help you diagnose and correct a pulling and/or steering wheel off-center issue. There is a diagnosis worksheet included to take on your test-drive and record your findings. These values are used to build the 15-digit DTC (diagnostic trouble code) that is required for your warranty claim. The last step in each repair procedure helps you create the correct code. In the rare case that you have to repair a vehicle that pulls and has the steering wheel off-center, use REPAIR PROCEDURE B to file your warranty claim. For more information, refer to Training Module SSC 44 - Steering Drift or Pull Interactive Service Bulletin. PROBABLE CAUSES Several conditions can cause the vehicle to pull or drift: ^ Wheel alignment ^ Tires ^ Off-center steering wheel (no pulling or drifting, but a customer may believe this is the case) CORRECTIVE ACTION Diagnose the problem using the special tools and the worksheet on page 4 that guides you to one of four repair procedures. TOOL INFORMATION Centering Tape (enough to diagnose 240 vehicles): T/N O7AAJ-001A300 Steering Drift Set Level: T/N 07AAJ-00100 Steering Drift Set: T/N O7MJ-001A140 Replacement Weight for Steering Drift Set: T/N 07AAJ-001A400 WARRANTY CLAIM INFORMATION In warranty: The normal warranty applies. Failed Part: P/N 53560-SDA-AO1 H/C 7139652 Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Customer Interest for Alignment: > 06-068 > May > 09 > Steering/Suspension - Vehicle Pulls Left/Right > Page 6111 Defect Code: 07406 Symptom Code: 03602 Skill Level: Repair Technician Diagnostic Trouble Code: To create the 15-digit DTC, see the applicable repair procedure. Out of warranty: Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work. TOOL DESCRIPTIONS The holding force gauge measures the amount of pull on the vehicle. It is a bracket that counts as one weight, plus five removable weights. During the test-drive, attach the bracket and the weights to the steering wheel on the side opposite the pulling direction. For example, if the vehicle pulls to the right, attach the bracket and weights to the left side of the steering wheel. Start with the maximum amount of weight on the steering wheel, and remove the weights until the vehicle drives in a straight line. When recording the pull on the worksheet, write down the direction of the pull (lefi or right) and the number of weights required to balance the pull (one through six). For example, if you have the bracket and two weights on the steering wheel, then record this as three weights. NOTE: The bracket counts as one weight. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Customer Interest for Alignment: > 06-068 > May > 09 > Steering/Suspension - Vehicle Pulls Left/Right > Page 6112 The road crown gauge measures the amount of road crown. Almost all roads have a crown to help drain water during rainstorms. Use the suction cup to attach the road crown gauge bracket to the vehicle in a vertical position. If necessary, bend the bracket until the gauge is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. There are two ways to calibrate the gauge: ^ Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is on the zero mark. ^ If you do not have a perfectly flat surface, park the vehicle on a reasonably flat surface and note the gauge reading. Turn the vehicle 1800 and, with the tires in the same spot, note the new gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3 and, after moving the vehicle, the gauge reads -1, then the difference is 4 degrees. Position the gauge to read +1. NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test-drive. If you plan to have an assistant help you during the test-drive, calibrate the gauge while both of you are sitting in the vehicle.

Place the sticker on the steering wheel when the steering wheel is straight. When you test-drive the vehicle, you can read how many millimeters the steering wheel is off-center.

It is a bracket that counts as one weight, plus five removable weights. During the test-drive, attach the bracket and the weights to the steering wheel on the side opposite the pulling direction. For example, if the vehicle pulls to the right, attach the bracket and weights to the left side of the steering wheel. Start with the maximum amount of weight on the steering wheel, and remove the weights until the vehicle drives in a straight line. When recording the pull on the worksheet, write down the direction of the pull (lefi or right) and the number of weights required to balance the pull (one through six). For example, if you have the bracket and two weights on the steering wheel, then record this as three weights. NOTE: The bracket counts as one weight.

Almost all roads have a crown to help drain water during rainstorms. Use the suction cup to attach the road crown gauge bracket to the vehicle in a vertical position. If necessary, bend the bracket until the gauge is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. There are two ways to calibrate the gauge: ^ Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is on the zero mark. ^ If you do not have a perfectly flat surface, park the vehicle on a reasonably flat surface and note the gauge reading. Turn the vehicle 1800 and, with the tires in the same spot, note the new gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3 and, after moving the vehicle, the gauge reads -1, then the difference is 4 degrees. Position the gauge to read +1. NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test-drive. If you plan to have an assistant help you during the test-drive, calibrate the gauge while both of you are sitting in the vehicle.

It is a bracket that counts as one weight, plus five removable weights. During the test-drive, attach the bracket and the weights to the steering wheel on the side opposite the pulling direction. For example, if the vehicle pulls Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6145 to the right, attach the bracket and weights to the left side of the steering wheel. Start with the maximum amount of weight on the steering wheel, and remove the weights until the vehicle drives in a straight line. When recording the pull on the worksheet, write down the direction of the pull (lefi or right) and the number of weights required to balance the pull (one through six). For example, if you have the bracket and two weights on the steering wheel, then record this as three weights. NOTE: The bracket counts as one weight. The road crown gauge measures the amount of road crown. Almost all roads have a crown to help drain water during rainstorms. Use the suction cup to attach the road crown gauge bracket to the vehicle in a vertical position. If necessary, bend the bracket until the gauge is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. There are two ways to calibrate the gauge: ^ Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is on the zero mark. ^ If you do not have a perfectly flat surface, park the vehicle on a reasonably flat surface and note the gauge reading. Turn the vehicle 1800 and, with the tires in the same spot, note the new gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3 and, after moving the vehicle, the gauge reads -1, then the difference is 4 degrees. Position the gauge to read +1. NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test-drive. If you plan to have an assistant help you during the test-drive, calibrate the gauge while both of you are sitting in the vehicle. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6146 The steering wheel offset gauge is a sticker that attaches to the steering wheel and the steering column cover. Place the sticker on the steering wheel when the steering wheel is straight. When you test-drive the vehicle, you can read how many millimeters the steering wheel is off-center. NOTE: If the vehicle is pulling, repairing the pull may correct the steering wheel offset. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6147 DIAGNOSTIC WORKSHEET REPAIR PROCEDURE A Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6148 NOTE: Do this repair procedure if, after doing step 10 of the test-drive, the vehicle pulled in the opposite direction after you swapped the front tires. 1. Swap wheels 2 and 4 on the passenger's side of the vehicle, and test-drive again. ^ If the pull goes away, replace the tire on wheel 2, then go to step 3. ^ If the pull does not go away, put wheels 2 and 4 back to their original positions, and go to step 2. 2. Swap wheels 1 and 3 on the driver's side of the vehicle, and test-drive again. ^ If the pull goes away, replace the tire on wheel 1, then go to step 3. ^ If the pull does not go away, use a known-good tire in position 1 and continue diagnosis. 3. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. REPAIR PROCEDURE B Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6149 1. Place the vehicle on a commercially available, computerized, four-wheel alignment rack, and record the following measurements. Follow the equipment manufacturer's instructions. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. 2. If any measurement is out of specification, inspect the front suspension for any damage. Repair any damaged parts before continuing your diagnosis. 3. Determine how the front wheel camber is affecting the pull. Pick the combination of left- and right-front camber that best matches the vehicle you are repairing, then note the camber thrust direction for that combination: NOTE: ^ If the camber of both front wheels is negative, but one wheel is grossly more negative than the other, the camber thrust direction will be opposite the wheel with more negative camber (for example, if the left-front wheel is more negative, the camber thrust direction is right). ^ If the camber of both front wheels is positive, but one wheel is grossly more positive than the other, the camber thrust direction will be the same as the wheel with more positive camber (for example, if the left-front wheel is more positive, the camber thrust direction is left). 4. Determine how the camber needs to be adjusted. 5. Adjust the camber as needed. Front Camber Adjustment, Double Wishbone Suspension Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6150 ^ Loosen the front subframe bolts. See the applicable service manual for more information. NOTE: The front wheels are being viewed from the rear of the vehicle. ^ Depending which way you need to shift the subframe, insert a pry bar between the subframe and body at both the front and rear positions of the subframe. NOTE: Be careful not to damage the vehicle. You could bend and damage the frame and/or body if you apply too much pressure. ^ Press on both pry bars to shift the subframe. It will move only a few millimeters. This should adjust the camber about 0.2-0.5°. ^ While holding the subframe in place, have an assistant torque the subframe bolts to their proper torque. Front Camber Adjustment, Strut Suspension ^ Raise the vehicle, and remove the front tires. ^ Loosen the damper pinch bolts and the flange nuts. ^ Adjust the camber by moving the bottom of the damper within the range of the damper pinch bolt free play. NOTE: Some vehicles have special pinch bolts that allow more adjustment. For more information, refer to the parts catalog. ^ Tighten the damper pinch bolts to the specified torque. ^ Reinstall the front wheels and lower the vehicle. Bounce the front of the vehicle several times to stabilize the suspension. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6151 6. Test-drive the vehicle to make sure it no longer pulls. If the steering wheel is now off-center by more than 2 mm, go to REPAIR PROCEDURE C. 7. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC. NOTE: Enter each reading in decimal degrees. Example 30' = 0.50. REPAIR PROCEDURE C 1. Make sure the steering wheel is centered. ^ Turn the steering wheel all the way to the right until it stops. ^ Turn the steering wheel all the way to the left, and count the number of revolutions until it stops. ^ Divide the number of revolutions in half, and turn the steering wheel until it is centered. For example, if it takes four revolutions of the steering wheel to go from lock to lock, then two turns is centered. ^ If the steering wheel is off-center by a large amount (20 mm or more), it may not be centered on the steering column shaft. Reinstall the steering wheel before going to step 2. 2. Place the vehicle on a lift, turn the steering wheel until it is centered, and then raise the vehicle. 3. Adjust the tie-rods. Use your measurements from question 13 of the test-drive to make your adjustment. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > All Technical Service Bulletins for Alignment: > Page 6152 ^ If the wheels are pointed to the right, shorten the driver's side tie-rod, and lengthen the passenger's side. ^ If the wheels are pointed to the left, shorten the passenger's side tie-rod, and lengthen the driver's side. ^ Each 360° turn of the tie-rod equals about 8 mm of steering wheel adjustment. For example, a steering wheel is off-center by 4 mm with the front wheels pointed right (when the steering wheel is centered). To correct the off-center, shorten the driver's side tie-rod by a half-turn, and lengthen the passenger's side tie-rod by a half-turn. 4. Use your diagnosis worksheet to fill in the following table and build your 15-digit DTC.

However, each of these adjustments are related to each other. For example, when you adjust camber, the toe will change. Therefore, you must adjust the front wheel alignment whenever you adjust camber or toe. Pre-Alignment Checks For proper inspection and adjustment of the wheel alignment, do these checks: 1. Release the parking brake to avoid an incorrect measurement. 2. Make sure the suspension is not modified. 3. Check the tire size and pressure. Tire size: Front/Rear: P195/65R15 89H Tire pressure (at cold): Front/Rear: 210 kPa (2.1 kgf/cm2, 30 psi) 4. Check the runout of the wheels and tires. 5. Check the suspension ball joints. (Hold a tire with your hands, and move it up and down and right and left to check for wobbling.) 6. Bounce the vehicle up and down several times to settle the suspension. 7. Check that the steering column is set at the center tilt and telescopic position. Caster Inspection Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions. Check the caster angle. Caster angle: 7°00' ± 1° ^ If the measurement is within specifications, measure the camber angle. ^ If the measurement is not within specifications, check for bent or damaged suspension components. Camber Inspection Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 6155 Front Camber Adjustment The front camber can be adjusted by exchanging one or both of the damper pinch bolts with a smaller diameter adjusting bolt. The difference between the adjusting bolt diameter and the pinch bolt hole diameter allows for a small range of adjustment. 1. Raise the front of the vehicle, and support it with safety stands in the proper locations. 2. Remove the front wheels. 3. Loosen the damper pinch bolts (A), and adjust the camber angle by moving the bottom of the damper within the range of the damper pinch bolt free play. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 6156 4. Tighten the damper pinch bolts to the specified torque. 5. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels. 6. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to settle the suspension. 7. Measure the camber angle. ^ If the measurement is within specification, measure the toe-in. ^ If the measurement is not within specification, go to step 8. 8. Raise the front of the vehicle, and support it with safety stands in the proper locations. 9. Remove the front wheels. 10. Replace the damper pinch bolts with the adjusting bolts (A), and adjust the camber angle. 11. Tighten the adjusting bolts to the specified torque value. 12. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels. 13. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to settle the suspension. 14. Measure the camber angle. If the camber angle is not within specification, repeat steps 8 through 13 to readjust the camber angle. If the camber measurement is correct, measure toe-in, and adjust it if necessary. Front Toe Inspection/Adjustment Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions. 1. Set the steering column to the center tilt and center telescopic position, then center the steering wheel spokes, and install a steering wheel holder tool. 2. Check the toe with the wheels pointed straight ahead. Front toe-in: 0±2 mm (0±0.08 in.) ^ If adjustment is required, go to step 3. ^ If no adjustment is required, go to rear toe inspection/adjustment. 3. Loosen the tie-rod locknuts (A) while holding the flat surface sections (B) of the tie-rod end with a wrench, and turn both tie-rods (C) until the front toe is within specifications. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 6157 4. After adjusting, tighten the tie-rod locknuts. Reposition the rack-end boot if it is twisted or displaced. 5. Go to rear toe inspection/adjustment. Rear Toe Inspection/Adjustment Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions. 1. Release the parking brake to avoid an incorrect measurement. 2. Check the toe. Rear toe-in: 2 +2 -1 mm (0.08 + 0.08 -0.04 in.) ^ If adjustment is required, go to step 3. ^ If no adjustment is required, remove the alignment equipment. 3. Hold the adjusting bolt (A) on the trailing arm (B), and remove the self-locking nut (C). 4. Replace the self-locking nut with a new one, and lightly tighten it. NOTE: ^ Always use a new self-locking nut whenever it has been loosened. ^ Reassemble the adjusting bolt and the adjusting cam plate with the eccentric facing up. 5. Adjust the rear toe by turning the adjusting bolt until the toe is correct. 6. Tighten the self-locking nut while holding the adjusting bolt. Turning Angle Inspection Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions. 1. Turn the wheel right and left while applying the brakes, and measure the turning angle of both wheels.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure.

The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

SENSOR POSITION CHECK When the TPMS sets a DTC, it refers to Tire 1, Tire 2, Tire 3, or Tire 4. In the service manual, the tire number is the sensor number. For example, Tire 2 is sensor 2. However, the tire number is not the tire position. To diagnose or repair the vehicle, do the sensor position check to find the location of the problem tire (or sensor) on the vehicle. 1. Turn the ignition switch to ON (II). 2. Connect the HDS to the vehicle. 3. On the HDS main screen, select the HDS icon. 4. On the HDS version screen, select the cars icon.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

If the instructions described are not properly followed, the airbags could accidentally deploy and cause damage or injuries. - Except when performing electrical inspections, always turn the ignition switch OFF, disconnect the negative cable from the battery, then wait for 3 minutes before starting work. NOTE: The SRS memory is not cleared even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. - Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs. - Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation. - Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors. - Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury. - Do not put objects on the front passenger's airbag. - The original audio and navigation system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system or the navigation system (if equipped), then write down the audio presets before disconnecting the negative cable from the battery. - Before returning the vehicle to the customer, enter the anti-theft codes for the audio system or the navigation system (if equipped), then enter the audio presets; set the clock. Steering-related Precautions Cable Reel Alignment - Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, and the horn inoperative. Center the cable reel whenever you do the following. Installation of the steering wheel - Installation of the cable reel - Installation of the steering column - Other steering-related adjustment or installation - Do not disassemble the cable reel. - Do not apply grease to the cable reel. - If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Airbag Handling and Storage Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, observe the following precautions. - Store the removed airbag with the pad surface up. Never put anything on the airbag. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Steering > Steering Column > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6296 - To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water. - Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200 °F/93 °C) - Never perform electrical inspections to the airbags, such as measuring resistance. - Do not position yourself in front of the airbag during removal, inspection, or replacement. - For proper disposal of a damaged airbag, refer to airbag disposal. - The side curtain airbag inflator assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag assembly, never do the following items: Handle the flexible bag. - Drop the curtain airbag. - Cut, tear, and peel the tapes.

The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Restraint Systems/Air Bag Systems/Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Steering > Steering Column > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6298 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

Opening the SRS Unit Shorting Connectors for Diagnosis Special Tools Required SRS short canceller 070AZ-SAA0100 NOTE: - To prevent damaging of the connector cavity, insert the short canceller straight into the cavity from the terminal side. - Before installing the short canceller, wash it with electric contact cleaner, then dry it with compressed air. - Do not use the short canceller if it is damaged. - Make sure to remove the short canceller before reconnection. When SRS unit connectors A (28P) or B (28P) are disconnected, a short circuit is created in the connector by its own function to prevent an airbag deployment. The circuit may need to be open sometimes when diagnosis is done on the system. Insert the short canceller (070AZ-SAA0100) in the specified cavities when it is necessary to keep the circuit open for diagnosis. Terminal numbers are shown from the wire side of the female terminals. Insert the short canceller(s) into the cavities on the terminal side of the connector.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

When the TPMS control unit detects low pressure in a tire, or a problem in the system, it turns on the appropriate indicator. ^ If low tire pressure is detected in one or more tires, the low tire pressure indicator comes on. ^ If a problem in the system is detected, the TPMS indicator comes on. ^ If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. If the system is OK, the TPMS indicator and the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If they don't, there is a problem with the system. If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit will set one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, the control unit turns off the indicators and stores the DTC(s). However, if the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator(s). NOTE: Tire pressures increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures can also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18°F (10°C) changes tire pressure by about 10 kPa (0.1 kgf/cm2, 1.5 psi). If the temperature drops, tire pressure could decrease just enough to turn on the low tire pressure indicator, but later, the tire temperature could increase enough to turn the indicator off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range 168 to 220 kPa (1.7 to 2.2 kgf/cm2, 24 to 32 psi). If a problem is detected in the system, the TPMS indicator comes on and stays on until the system returns to normal with most DTCs. If DTC 81, 83 or 85 is set, the TPMS indicator goes off only when the ignition switch is turned to LOCK (0). When a flat tire is replaced with the spare tire, the TPMS indicator comes on (DTC 32, 34, 36 or 38) because the system is no longer receiving the signal from the tire's transmitter. This is not a problem with the spare tire.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Wheels and Tires > Tire Monitoring System > Tire Pressure Monitor Receiver / Transponder > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 6575 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Steering and Suspension > Wheels and Tires > Tire Monitoring System > Tire Pressure Sensor > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 6597 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6689 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6690 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6707 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6708 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6709 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6710 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6711 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6712 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6713 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6714 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Blower Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 6715 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6770 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6771 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6778 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6788 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6789 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6790 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6791 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6792 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6793 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6794 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6795 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Diagrams > Diagram Information and Instructions > Page 6796 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection Refrigerant: Technical Service Bulletins A/C - Refrigerant Leak Detection 07-030 October 12, 2007 Applies To: ALL Vehicles With Conventional A/C Compressors A/C Leak Detection (Supersedes 07-030, dated June 15, 2007, to update the information marked by asterisks) The OPTIMAX Jr. (TM)A/C Leak Detection Kit for Honda vehicles, P/N TRP124893, is a new required tool. The kit is used to add small amounts of dye to A/C systems to help locate smaller leaks that an electronic leak detector might not find. When searching for leaks, always begin by using an electronic leak detector. Refer to Service Bulletin 97-027, Denso HLD-100 Halogen Leak Detector; for tips on using this tool, then follow up with the OPTIMAX Jr. This new detection kit complements but does not replace the electronic detector. The kit contains: ^ TRP8640CS, OPTIMAX Jr. (TM) cordless, fluorescent leak detection flashlight lamp (includes 3 standard AA batteries) ^ TRP38600601, (6) 0.06 oz. (1.7 g) Tracer-Stick(R) R134a/PAG A/C dye capsules with ID labels ^ TRP3887, R-134a Universal Connect Set(TM) ^ TRP120884, GLO-AWAY(TM) dye cleaner ^ TRP9940, fluorescence-enhancing glasses ^ TRP1143, (1) empty Tracer-Stick dye capsule ORDERING INFO *One OPTIMAX Jr. A/C Leak Detection Kit was shipped to each current dealer as a required special tool. Additional kits and replacement capsules may be ordered through the Honda Tool and Equipment Program. On the iN, click on Service, Service Bay, Tool and Equipment Program, Online Catalog tab, and Air Conditioning Equipment, or call.* NOTICE ^ Do not use leak-trace dye in any Honda hybrid vehicle equipped with a dual-scroll compressor This can increase the chance of electric shock. The compressor is easily identified by the orange high-voltage cable that is connected to the compressor body. ^ Only Tracer-Stick single-dose fluorescent dye capsules from Tracer Products (Tracerline(R)) are approved for use in Honda vehicles. Other dyes contain solvents that may contaminate the system's refrigerant oil, leading to component failure. ^ Adding excessive amounts of dye can lead to compressor damage and failure. USING THE OPTIMAX JR. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection > Page 6844 1. Before adding any leak-detection dye, check to see if there is dye in the system now. ^ Check for a label in the engine compartment indicating that fluorescent leak-detection dye has been added to the system. ^ Dye may have been added even though no label is present. To confirm this: - Put on the fluorescence-enhancing glasses, and remove the low-side service port sealing cap. - Direct the ultraviolet lamp into the valve stem area. If dye has been previously added, the lubricant traces will have a bright yellow fluorescent glow. You may need to press the port's valve stem briefly to release some lubricant and dye from the system. ^ If there is no dye in the system, go to step 2. ^ If there is dye in the system, go to step 5. Do not add more dye. 2. Add the dye. NOTE: Air and moisture must be evacuated from the universal connect set if it is being used for the first time, or if it has been stored with the control valve open. If the air and moisture have been evacuated, go to step 3; otherwise do the following: (a) Attach the empty dye capsule (provided in the dye kit) to the control valve fitting. (b) Attach the service valve fitting (provided in the kit) to the empty dye capsule. (c) Attach the low-side hose of the A/C recovery and charging station, and open the quick coupler's hand-wheel valve. Then open the control valve (black knob) on the universal connect set. (d) Following the manufacturer's instructions for your recovery and charging station, evacuate the universal connect set for approximately 3 minutes. (e) When evacuation is complete, be sure the set's control valve is closed (finger tight), and disconnect the NC recovery and charging station. (f) Remove the service valve fitting and the empty dye capsule from the set, and store them for future use. NOTE: ^ Check the refrigerant charge level. There must be enough refrigerant in the system to operate the A/C compressor and to circulate refrigerant oil. ^ If the refrigerant charge is too low, recover the remaining amount and recharge the system before adding any dye. (g) Start the vehicle and operate the A/C system. Follow your A/C refrigerant recovery and charging station's operating instructions for low-side charging to install the dye. * NOTE: Only 0.05 lb (0.02 kg) of refrigerant is needed to push the dye into the A/C system.* (h) Once the refrigerant charge is programmed, open the control valve on the set to allow the dye to enter the system. (i) After the dye capsule clears, allow the low-side of the A/C system to reach its lowest operating pressure, then quickly close both the service equipment's low-side coupler valve and the control valve on the set. (j) Remove the set from the vehicle by releasing its quick coupler. Remove the empty dye capsule from the service valve fitting. Return the hose, control valve, and service-valve fitting to the storage case. * NOTE: Store the hose with the control valve closed. This will retain a small amount of refrigerant in the hose so it does not have to be evacuated the next time you use it.* (k) Fill out an identification label (provided in the kit), and attach it to a location near the A/C charge label. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection > Page 6845 3. Connect the universal connect set and the Tracer- Stick dye capsule: (a) Be sure the quick coupler and control valves on the set are closed. (b) Remove the low-side service port sealing cap, and connect the set to the low-side service port using the quick coupler. (c) Hold a new dye capsule so that the embossed arrow is pointing up. Remove the black end cap, and carefully attach the capsule to the control valve fitting. NOTE: The capsule must be held with the embossed arrow pointing up or the dye will leak out of the capsule. (d) Turn the capsule so the embossed arrow is pointing down. Remove the orange end cap, and carefully attach the service valve fitting provided in the kit (finger tight). NOTE: The capsule must be held with the embossed arrow pointing down or the dye will leak out. 4. Connect the NC service equipment: With the universal connect set and dye capsule attached to the vehicle's low-side service port, connect the A/C refrigerant recovery and charging station's low-side hose quick coupler to the service valve fitting. Open the blue hand-wheel valves on both quick couplers. Leave the control valve (black knob) on the universal connect set closed. NOTE: * ^ If you have recovered refrigerant to weigh it as part of your diagnostics, or if there is a low charge, it is more efficient to recharge the system using normal procedures before installing the universal connect set. Dye can then be added using approximately 0.05 lb (0.02 kg) of refrigerant.* ^ You do not need to connect the service equipment's high-side hose to the vehicle to install the dye. If the high-side hose is connected, make sure its coupler valve is closed before proceeding. ^ Do not use the A/C recovery and charging station to recover or evacuate the A/C system when a full dye capsule is attached. The dye will be drawn into the service equipment instead of being added to the vehicle's A/C system. 5. Inspect the A/C system for leaks: (a) Run the A/C system for at least 15 minutes to circulate the dye through the system. Large leaks will be seen immediately as a fluorescent yellow glow. Smaller leaks may require at least 24 hours of vehicle operation before they become visible. Operate the A/C system as much as possible during this time to keep the dye circulating. (b) Stop the vehicle's engine and inspect the system for leaks using the ultraviolet (UV) lamp and fluorescence-enhancing glasses from the kit. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Heating and Air Conditioning > Refrigerant > Component Information > Technical Service Bulletins > A/C - Refrigerant Leak Detection > Page 6846 Low ambient light conditions (a dark work area) will aid in locating the leak. NOTE: Not all UV lamps work well with all types of fluorescent dye. Use only the lamp provided in the kit to inspect for leaks. (c) Inspect the entire system. Be sure to check these locations: ^ damaged and corroded areas ^ fittings ^ hose-to-line couplings ^ refrigerant controls ^ service ports ^ brazed or welded areas ^ areas near attachment points (d) Check for evaporator leaks by illuminating the evaporator drain tube area with the UV lamp and glasses. (e) After repairing a leak, remove any fluorescent residue using the GLO-AWAY dye cleaner from the kit and hot water (follow the instructions on the bottle).

Installation of the steering wheel - Installation of the cable reel - Installation of the steering column - Other steering-related adjustment or installation - Do not disassemble the cable reel. - Do not apply grease to the cable reel. - If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Airbag Handling and Storage Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, observe the following precautions. - Store the removed airbag with the pad surface up. Never put anything on the airbag. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6907 - To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water. - Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200 °F/93 °C) - Never perform electrical inspections to the airbags, such as measuring resistance. - Do not position yourself in front of the airbag during removal, inspection, or replacement. - For proper disposal of a damaged airbag, refer to airbag disposal. - The side curtain airbag inflator assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag assembly, never do the following items: Handle the flexible bag. - Drop the curtain airbag. - Cut, tear, and peel the tapes. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6908 SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor, Front Passenger's Weight Sensors and Rear Safing Sensor - Turn the ignition switch OFF, disconnect the negative cable from the battery then wait for 3 minutes before starting installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit. - Be careful not to bump or impact the SRS unit, front impact sensors, side impact sensors, or rear safing sensor whenever the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF. - During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, front impact sensors, the side impact sensors, or rear safing sensor. The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6909 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 6910 Spring-loaded Lock Connector Some SRS system connectors have a spring-loaded lock.

The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Air Bag Systems/Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 7026 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7058 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554.

Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7066 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7076 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7077 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7078 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7079 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7080 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7081 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7082 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7083 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Restraint Systems > Seat Belt Systems > Seat Belt Tensioner > Component Information > Diagrams > Diagram Information and Instructions > Page 7084 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Never tow the vehicle behind another vehicle with a rope or chain. It is very dangerous. Emergency Towing There are three popular methods of towing a vehicle. Flat-bed Equipment - The operator loads the vehicle on the back of a truck. This is the best way of transporting the vehicle. To accommodate flat-bed equipment, the vehicle is equipped with front towing hooks (A), front tie down hook slots (B), a rear towing hook (C), and rear tie down hook slots (D). The towing hooks can be used with a winch to pull the vehicle onto the truck, and the tie down slots can be used to secure the vehicle to the truck. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Towing Information > System Information > Service and Repair > Page 7283 Wheel Lift Equipment - The tow truck uses two pivoting arms that go under the tires (front or rear) and lift them off the ground. The other two wheels remain on the ground. This is an acceptable way of towing the vehicle. Sling-type Equipment - The tow truck uses metal cables with hooks on the ends. These hooks go around parts of the frame or suspension, and the cables lift that end of the vehicle off the ground. The vehicle's suspension and body can be seriously damaged if this method of towing is attempted. This method of towing the vehicle is unacceptable. If the vehicle cannot be transported by a flat-bed, it should be towed with the front wheels off the ground. If the vehicle is damaged, and must be towed with the front wheels on the ground, or with all four wheels on the ground, do this: Manual Transmission - Release the parking brake. - Shift the transmission to neutral. - Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock - Make sure all accessories are turned off to minimize battery current draw. Automatic Transmission - Release the parking brake. - Start the engine. - Shift to the D position, then to the N position. - Turn off the engine. - Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock - Make sure all accessories are turned off to minimize battery current draw. It is best to tow the vehicle no farther than 50 miles (80 km), and keep the speed below 35 mph (55 km/h). NOTICE: - Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shift the transmission or start the engine (automatic transmission), the vehicle must be transported on a flat-bed. - Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not designed to support the vehicle's weight.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Front Door > Front Door Window Glass > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision Front Door Window Glass Weatherstrip: Technical Service Bulletins Body - Power Window Diagnostics Revision 10-011 March 5, 2010 Applies To: See VEHICLES AFFECTED Service Manual Update: Power Window Goes Up and Reverses On Its Own, Is Slow to Open and Close, or Squeals, Creaks, Clunks, or Clicks BACKGROUND The information in this service bulletin addresses three power window problems that are not currently covered in the service manuals. VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Front Door > Front Door Window Glass > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 7355 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Front Door > Front Door Window Glass > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 7356 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2.

Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Rear Door > Rear Door Window Glass > Rear Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision Rear Door Window Glass Weatherstrip: Technical Service Bulletins Body - Power Window Diagnostics Revision 10-011 March 5, 2010 Applies To: See VEHICLES AFFECTED Service Manual Update: Power Window Goes Up and Reverses On Its Own, Is Slow to Open and Close, or Squeals, Creaks, Clunks, or Clicks BACKGROUND The information in this service bulletin addresses three power window problems that are not currently covered in the service manuals. VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Rear Door > Rear Door Window Glass > Rear Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 7417 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Doors, Hood and Trunk > Doors > Rear Door > Rear Door Window Glass > Rear Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 7418 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2.

Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7619 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7620 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7629 2.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7637 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7638 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7639 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7640 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7641 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7642 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7643 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7644 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 7645 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

If the instructions described are not properly followed, the airbags could accidentally deploy and cause damage or injuries. - Except when performing electrical inspections, always turn the ignition switch OFF, disconnect the negative cable from the battery, then wait for 3 minutes before starting work. NOTE: The SRS memory is not cleared even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. - Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs. - Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation. - Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors. - Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury. - Do not put objects on the front passenger's airbag. - The original audio and navigation system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system or the navigation system (if equipped), then write down the audio presets before disconnecting the negative cable from the battery. - Before returning the vehicle to the customer, enter the anti-theft codes for the audio system or the navigation system (if equipped), then enter the audio presets; set the clock. Steering-related Precautions Cable Reel Alignment - Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, and the horn inoperative. Center the cable reel whenever you do the following. Installation of the steering wheel - Installation of the cable reel - Installation of the steering column - Other steering-related adjustment or installation - Do not disassemble the cable reel. - Do not apply grease to the cable reel. - If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Airbag Handling and Storage Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, observe the following precautions. - Store the removed airbag with the pad surface up. Never put anything on the airbag.

The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Restraint Systems/Air Bag Systems/Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Interior Moulding / Trim > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 7657 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions Heated Element: Diagram Information and Instructions Circuit Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7780 Circuit Schematics Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7781 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7782 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7789 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7799 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7800 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7801 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7802 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7803 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7804 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7805 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7806 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Mirrors > Heated Element, Mirror > Component Information > Diagrams > Diagram Information and Instructions > Page 7807 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information Paint: Technical Service Bulletins Paint - Defect Warranty Claim Information 10-002 January 20, 2010 Applies To: ALL Photos For Warranty Paint Repair Claims BACKGROUND American Honda, its factories, and its suppliers are constantly striving to increase the quality, durability, and reliability of Honda vehicles. In the interest of making such improvements, as of March 2009, American Honda requires that digital photographs be taken of paint defects submitted for warranty repair. Examples of paint defects include mismatched colors, dirt in the paint, gloss issues, paint runs, "hiding" (thin paint), etc. Photos of these defects help provide valuable product information to the factory for quicker analysis and development of countermeasures. As a result, each Honda dealer is required to: ^ Take digital photos of paint defects submitted for warranty consideration. ^ Obtain DPSM authorization prior to starting any warranty paint repair. ^ Store warranty paint claim photos for 12 months, in accordance with the document retention policy outlined in the current Service Operations Manual. NOTE: A warranty claim may be subject to debit if the photos submitted do not adequately show the customer's paint complaint. WARRANTY CLAIM INFORMATION None. This service bulletin is for information only. PAINT DEFECT PHOTO GUIDELINES ^ Before photographing the paint defect, wash and completely dry the vehicle. Dirt, dust, and water spots visible in the photos may cover the paint defects and make them difficult to diagnose. ^ To properly document each warranty paint repair claim, four to five photos are required. These photos must be taken using a digital camera with "macro" focusing capabilities to provide detailed, in-focus close-ups. ^ For maximum clarity, the file size for each photo must be between 500 kb and 2,000 kb (2 mb). ZIP-compressed files are not acceptable. ^ Cell phone photos are not acceptable because of the phone's lack of focusing capability. ^ Before committing to paint repair, ensure that the photos you've taken are clear and in focus, and meet the standards and required number and type of photos for warranty claim submittal. ^ It's best to shoot multiples of each required shot; this gives you the widest choice of photos to choose from.

PAINT DEFECT PREPARATION Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information > Page 7832 ^ Before taking photos, outline the paint defect with a wide-tip Sharpie marker pen, a crayon, a grease pencil, masking tape, or stick-on paper notes. The marking material must contrast with the color of the paint, and should clearly identify the paint defect area. ^ If the paint defect extends across body panels, run the marking material across the panels to show the location and full extent of the paint defect. ^ Alternatively, if you have a computer program that allows you to draw on digital photographs, you can use that to outline the defect area(s) on your photos. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information > Page 7833 TIPS FOR TAKING HIGH-QUALITY PAINT DEFECT PHOTOS Automotive paint has evolved into an elaborate combination of color pigments, solid metallic flakes, pearl (coated mica), and transparent toners in the clear coat that give the paint its depth, color, and gloss. As a result, some paint defects photograph better outdoors, while others do so indoors. To help decide where to photograph the defect, first determine whether the customer complaint is for a surface paint defect, or if the defect is below the paint's surface. As a general rule: ^ Surface paint defects photograph better inside a shop with artificial light, such as that produced by overhead fluorescent tubes. While viewing the vehicle through the camera's viewfinder or LCD screen, move the camera to position the fluorescent light's reflections over and around the defect, carefully watching for distortions in the light that best reveal the surface defect. ^ Most paint defects photograph better with the flash off, the exception being dirt or fingerprints embedded in the paint, which may be highlighted by the flash's reflection. To determine which method will provide the best shots, take one shot with the flash on, and another with it off, then compare the two. NOTE: Photographing with the flash off might extend the shutter time, and may require the camera to be stabilized by mounting it on a tripod, or by holding it against something rigid. ^ Paint defects under the clear coat surface photograph better outside in natural light, with the sun low in the sky, behind the photographer, and facing the defect. The hours between 8-11 a.m. and 2-6 p.m. usually provide the best light to photograph defects within the paint, as the sunlight at these times allows you to see through the clear coat into the paint. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information > Page 7834 ^ When shooting a defect under the surface, first look at it straight-on, then move to look at the defect from multiple angles, carefully watching for the best light that reveals the defect, then snap that view of the defect with your camera. If needed, you may have to reposition the vehicle in relation to its light source to clearly reveal and photograph the paint defect. REQUIRED PHOTOS TO MEET HONDA WARRANTY PAINT CLAIM STANDARDS To properly document each warranty paint repair claim, four to five photos must be taken, as described below: Photo One: Take a readable, in-focus shot of the vehicle's barcoded VIN sticker on the driver's side doorjamb. Note: If you shoot this using your camera's flash, make sure the flash's reflection does not reduce the VIN sticker's readability. Photo Two: Take an orientation shot of the entire paint defect area, with the lens zoomed out wide enough to show the defect's location in relation to other body parts, such as door handles, windshield, headlights, bumper, side windows, wheel, etc. Photos Three and Four: Take the third shot closer to the defect and from a different angle, to add more detail to the warranty repair claim. Then, if needed to further support the claim, take a fourth shot from another angle to make sure that the defect and/or its full extent are completely documented. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information > Page 7835 Photo Five: Take the last required shot as a sharply focused macro close-up, about 4 inches (100 mm) from the defect, showing exactly what the paint defect is. For example, if the defect is a mismatch in color, take a macro close-up of the mismatched panel and the correct color body panel together in the same shot. Note: To achieve a clear, close-up photo at this distance, you may have to manually focus the camera. UNACCEPTABLE PAINT DEFECT PHOTOGRAPH EXAMPLES This photo is unacceptable because: ^ it is out-of-focus and unreadable, and ^ the file size is too small (351 kb). This photo is unacceptable because: ^ it is too dark, and ^ it lacks focus, detail, and marking materials that identify the area and extent of the paint defect, as specified in this service bulletin and per warranty claim submittal standards. CORRECTING PAINT DEFECT PHOTO PROBLEMS USING PICTURE MANAGER Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Technical Service Bulletins > Paint - Defect Warranty Claim Information > Page 7836 Microsoft Office Picture Manager is a very useful tool to help improve the quality of paint defect photos submitted for warranty consideration. While the Picture Manager program cannot correct blurry, out-of-focus pictures, it can adjust pictures for brightness, contrast, and color, helping to reveal details.

This information provides information on paint defect, repair, and refinishing. Throughout, the objective is to explain in a simple yet comprehensive manner the basic items you should know about paint repairs. Select the correct material for the defect and repaint or refinish in the correct manner as described in this information. Basic Rules for Repairing a Paint Finish To repair paint damage, always use the 2-part acrylic urethane paints designated; polish and bake each of the three coats, as in production, to maintain the original film thickness, and to assure the same quality as the original finish. Outline of factory painting process Features In Each Work Process Pretreatment and electrodeposition In the pretreatment process, the entire body is degreased, cleaned, and coated with zinc phosphate by dipping. After the body has been cleaned with pure water, it is placed in an electrolytic bath of soluble primer (Cationic Electrodeposition). This produces a thorough corrosion inhibiting coating on the inner surface and corners of the body, pillars, sills, and panel joints. Chipping primer is then applied to the most susceptible areas. Intermediate coat The intermediate coat is applied to the prepared surface to further protect against damage. Top coat Enamel paint and either polyester or acrylic resin paint are used in the top coat for higher solidity, smoothness, brightness, and weather resistance. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Description and Operation > Paint Information > Page 7852 Paint: Description and Operation Soft Chipping Guard Primer Coat General Safety Precautions The removal of paint and undercoating by stone chips immediately exposes metal to the atmosphere, causing it to oxidize. The thickness of this oxidation increases if the process continues unchecked. The soft chipping guard primer protects against damage due to the impact of such objects. - The soft chipping guard primer coat is applied over the E. D. (Electrostatically Deposited) primer. It is followed by guide coating and top coating. - The soft chipping guard primer produces a smooth surface when dry. It should be sprayed so the thickness of the protective film is 20 microns. - A soft chipping guard primer coat is then applied to the most susceptible area. - Spray the primer surface (2-part urethane primer surfacer) on the soft chipping guard primer coating areas when you replace parts using soft chipping guard primer coat. Coating Procedures WARNING: - Wear goggles or safety glasses to prevent eye injury. - Ventilate when spraying undercoat. 1. Sanding the replacement part. Use a double action sander and P400 disc sandpaper. NOTE: Do not oversand the edges or corners of the part. - Do not expose base metal. 2. Air blowing/degreasing. Use alcohol, and wax and grease remover. 3. Protect from overspray. Use masking tape and paper to protect the related areas from overspray. 4. Spraying primer surfacer. - Spray about 4 to 5 coats to get 20 microns of thickness. One coat deposits about 5 to 7 microns. - Do not try to cover the surface with one heavy coat. Applying several thin coats is recommended. - Use a 2-part urethane primer surfacer and a spray gun. - Mix the primer surfacer with the correct ratio of additive and solvent. - Follow the primer surfacer manufacturer's instructions. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Paint, Striping and Decals > Paint > System Information > Description and Operation > Paint Information > Page 7853 5. Drying. After spraying primer surfacer, allow 7 to 10 minutes of drying time, then force dry it with infrared lamps or an industrial dryer. 6. Polishing. - Check that the primer surfacer has dried thoroughly, then sand the primer surfacer. - Use a double action sander and P400 P600 disc sandpaper. 7. Intermediate coating and top coating.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 7994 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 7995 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8002 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8012 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8013 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8014 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8015 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8016 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8017 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8018 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8019 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Seats > Seat Heater > Component Information > Diagrams > Diagram Information and Instructions > Page 8020 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Weatherstrip > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 8133 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Body and Frame > Weatherstrip > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 8134 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2.

Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8188 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8189 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8206 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8207 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8208 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8209 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8210 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8211 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8212 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8213 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8214 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8221 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8222 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8229 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8231 2.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8239 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8240 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8241 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8242 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8243 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8244 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8245 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8246 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 8247 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

If the instructions described are not properly followed, the airbags could accidentally deploy and cause damage or injuries. - Except when performing electrical inspections, always turn the ignition switch OFF, disconnect the negative cable from the battery, then wait for 3 minutes before starting work. NOTE: The SRS memory is not cleared even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. - Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs. - Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation. - Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors. - Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury. - Do not put objects on the front passenger's airbag. - The original audio and navigation system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system or the navigation system (if equipped), then write down the audio presets before disconnecting the negative cable from the battery. - Before returning the vehicle to the customer, enter the anti-theft codes for the audio system or the navigation system (if equipped), then enter the audio presets; set the clock. Steering-related Precautions Cable Reel Alignment - Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, and the horn inoperative. Center the cable reel whenever you do the following. Installation of the steering wheel - Installation of the cable reel - Installation of the steering column - Other steering-related adjustment or installation - Do not disassemble the cable reel. - Do not apply grease to the cable reel. - If the cable reel shows any signs of damage, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel. Airbag Handling and Storage Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of an airbag during service, observe the following precautions. - Store the removed airbag with the pad surface up. Never put anything on the airbag. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 8272 - To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water. - Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200 °F/93 °C) - Never perform electrical inspections to the airbags, such as measuring resistance. - Do not position yourself in front of the airbag during removal, inspection, or replacement. - For proper disposal of a damaged airbag, refer to airbag disposal. - The side curtain airbag inflator assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag assembly, never do the following items: Handle the flexible bag. - Drop the curtain airbag. - Cut, tear, and peel the tapes. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 8273 SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor, Front Passenger's Weight Sensors and Rear Safing Sensor - Turn the ignition switch OFF, disconnect the negative cable from the battery then wait for 3 minutes before starting installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit. - Be careful not to bump or impact the SRS unit, front impact sensors, side impact sensors, or rear safing sensor whenever the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF. - During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, front impact sensors, the side impact sensors, or rear safing sensor. The airbags could accidentally deploy and cause damage or injury. - After a collision where a front airbag, side airbag or a seat belt tensioner, seat belt buckle tensioner deployed, go to Component Replacement/Inspection After Deployment. See: Restraint Systems/Air Bag Systems/Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, side impact sensors, or rear safing sensor. If there is any damage, replace the SRS unit and/or the sensors. - Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor. - Be sure the SRS unit, front impact sensors, side impact sensors, and rear safing sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft). Whenever you remove or replace the SRS unit, safing sensor, or all impact sensors, always install the components with new bolts. - Do not spill water or oil on the SRS unit or the side impact sensors. Wiring Precautions Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the instructions. - Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Dashboard / Instrument Panel > Air Bag(s) Arming and Disarming > System Information > Service and Repair > Page 8274 - Be sure to install the harness wires so they do not get pinched or interfere with other parts. - Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose. Precautions for Electrical Inspections - When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector. - Use a U-shaped probe. Do not insert the probe forcibly. - Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions Fuel Gauge: Diagram Information and Instructions Circuit Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8302 Circuit Schematics Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8303 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8304 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8321 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8322 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8323 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8324 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8325 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8326 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8327 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8328 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Fuel Gauge > Component Information > Diagrams > Diagram Information and Instructions > Page 8329 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit will set one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, the control unit turns off the indicators and stores the DTC(s). However, if the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator(s). NOTE: Tire pressures increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures can also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18°F (10°C) changes tire pressure by about 10 kPa (0.1 kgf/cm2, 1.5 psi). If the temperature drops, tire pressure could decrease just enough to turn on the low tire pressure indicator, but later, the tire temperature could increase enough to turn the indicator off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range 168 to 220 kPa (1.7 to 2.2 kgf/cm2, 24 to 32 psi). If a problem is detected in the system, the TPMS indicator comes on and stays on until the system returns to normal with most DTCs. If DTC 81, 83 or 85 is set, the TPMS indicator goes off only when the ignition switch is turned to LOCK (0). When a flat tire is replaced with the spare tire, the TPMS indicator comes on (DTC 32, 34, 36 or 38) because the system is no longer receiving the signal from the tire's transmitter. This is not a problem with the spare tire.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Malfunction Indicator Lamp > Component Information > Description and Operation Malfunction Indicator Lamp: Description and Operation Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness Codes) The vehicle has certain "readiness codes" that are part of the on-board diagnostics for the emissions systems. If the vehicle's battery has been disconnected or gone dead, if the DTCs have been cleared, or if the PCM has been reset, these codes are reset. In some states, part of the emissions testing is to make sure these codes are set to complete. If all of them are not set to complete, the vehicle may fail the test, or the test cannot be finished. To check if the readiness codes are set to complete, turn the ignition switch ON (II), but do not start the engine. The MIL will come on for 15-20 seconds. If it then goes off, the readiness codes are complete'. If it flashes five times, one or more readiness codes are not complete. To set each code, drive the vehicle or run the engine as described in the procedures.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8397 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8398 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8415 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8416 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8417 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8418 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8419 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8420 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8421 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8422 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Oil Pressure Warning Lamp/Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8423 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Outside Temperature Display > Component Information > Adjustments Outside Temperature Display: Adjustments Outside Air Temperature Indicator Calibration Description The outside temperature sensor is located behind the center of the front bumper. The gauge control module (tach) uses measurements from this sensor to display the outside air temperature. Because of the location of the sensor, it may be affected by heat reflection from the road, engine and radiator heat or hot exhaust from surrounding traffic. These conditions can heat soak the outside air temperature sensor and cause inaccurate readings. Logic has been written into the gauge control module (tach) to help prevent abnormal or fluctuating outside air temperature indicator readings. Outside Air Temperature Indicator Logic Initial outside air temperature indication after the ignition switch is turned ON (II). - If the engine coolant temperature is 140 °F (60 °C) or higher when the ignition switch is turned ON (II), the outside air temperature indicated the last time the key was turned off will be displayed regardless of the current temperature measured by the outside air temperature sensor. - If the engine coolant temperature is 139 °F (59 °C) or lower when the ignition switch is turned ON (II), the current temperature measured by the outside air temperature sensor will be indicated. Update to the outside air temperature indicator while driving If the temperature measured by the outside air temperature sensor is greater than the temperature on the outside air temperature indicator, the outside temperature indicator will increase by 1.8 °F (1 °C) per minute after the vehicle speed is greater than 19 mph (30 km/h) for more than 1 minute and 30 seconds. It will continue to increase until the current outside air temperature is indicated. So, the first change to the outside air temperature indicator is 1 minute and 30 seconds after the vehicle speed is greater than 19 mph (30 km/h). If the vehicle speed drops below 19 mph (30 km/h), the indicator will not update again until the vehicle speed is increased to 19 mph (30 km/h) or more for more than 1 minute and 30 seconds again. If the outside air temperature is less than the indicated temperature, the temperature will decrease 1 °F every 1.1 seconds (1 °C every 2 seconds) until the current outside air temperature is indicated regardless of vehicle speed. Troubleshooting If the indicator displays "--------" for more than 2 seconds after selecting the outside air temperature display mode, check the outside air temperature sensor, or gauge control module self-diagnosis. Calibration The outside air temperature indicator's displayed temperature can be recalibrated ±5 °F (or ±3 °C) to meet the customer's expectations. 1. Turn the ignition switch ON (II). 2. Select the outside air temperature display. 3. Press and hold the SEL/RESET switch until the trip meter resets, then release it. Press, and continue to hold, the switch again, and the display will scroll through temperature settings from +5 °F to -5 °F (or +3 °C to -3 °C) as shown. 4. When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed. Example: Incorrect value = 68 ° F (20 °C) Desired correction value = +2 ° F (+1 °C) Correct valve = 70 ° F (21° C) Desired correction value = -2 ° F (-1 ° C) Correct valve = 66 ° F (19 ° C) NOTE: The recalibration temperature is not the value the sensor sees. Therefore the temperature can only be adjusted 5 degrees from the sensor. NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8483 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8484 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8491 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8501 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8502 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8503 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8504 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8505 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8506 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8507 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8508 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Shift Indicator > Component Information > Diagrams > Diagram Information and Instructions > Page 8509 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

When the TPMS control unit detects low pressure in a tire, or a problem in the system, it turns on the appropriate indicator. ^ If low tire pressure is detected in one or more tires, the low tire pressure indicator comes on. ^ If a problem in the system is detected, the TPMS indicator comes on. ^ If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. If the system is OK, the TPMS indicator and the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If they don't, there is a problem with the system. If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit will set one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, the control unit turns off the indicators and stores the DTC(s). However, if the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator(s). NOTE: Tire pressures increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures can also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18°F (10°C) changes tire pressure by about 10 kPa (0.1 kgf/cm2, 1.5 psi). If the temperature drops, tire pressure could decrease just enough to turn on the low tire pressure indicator, but later, the tire temperature could increase enough to turn the indicator off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range 168 to 220 kPa (1.7 to 2.2 kgf/cm2, 24 to 32 psi). If a problem is detected in the system, the TPMS indicator comes on and stays on until the system returns to normal with most DTCs. If DTC 81, 83 or 85 is set, the TPMS indicator goes off only when the ignition switch is turned to LOCK (0). When a flat tire is replaced with the spare tire, the TPMS indicator comes on (DTC 32, 34, 36 or 38) because the system is no longer receiving the signal from the tire's transmitter. This is not a problem with the spare tire.

All TPMS sensors: ^ Are mounted on the inside of the rim, connected to the valve stem. ^ Use a wireless transmission to send tire pressure and temperature information to the TPMS unit. ^ Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used. Initiator-Type TPMS (Location-Type TPMS) *The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08 Odyssey Touring models.* Initiator-less TPMS (No Location-Type TPMS) The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Tire Monitoring System > Tire Pressure Monitor Receiver / Transponder > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 8540 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button a second time within 30 seconds, the battery quick charge mode begins. ^ Once the batteries are discharged, the LEDs turn solid red and the battery quick charge mode begins.

The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a code for each tire. NOTE: ^ During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number. ^ Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this bulletin.

See TOOL DESCRIPTION for more information. WARRANTY CLAIM INFORMATION None. TOOL INFORMATION TOOL DESCRIPTION TPMS Sensor Tool The TPMS sensor tool is a wireless tool that is used with the HDS for troubleshooting (sensor position check) and for replacing TPMS sensors or the control unit (sensor ID learning). General use: ^ Always make sure the TPMS sensor tool is set to low power unless otherwise instructed. *^ Make sure there are no vehicles or other wheels with TPMS sensors within 10 feet of the vehicle you are working on. ^ Make sure the batteries are in good condition and secure in the case. Refer to ServiceNews article A07050D, Keep Those TPMS Sensor Tool Batteries From Popping Loose, for more information.* ^ Turn on the TPMS sensor tool by following the HDS instructions. There are two different wavelengths used, and there are two ways to turn on the TPMS sensor tool. If the TPMS sensor tool is not turned on correctly, you won't be able to troubleshoot the vehicle or do the sensor ID learning procedure. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Tire Monitoring System > Tire Pressure Sensor > Component Information > Technical Service Bulletins > Tire Monitor System - Usage of TPMS Sensor Tools > Page 8562 ^ Turn off the TPMS sensor tool by pressing and holding the small button as shown until the green light in the button turns off. The tool will also turn off after 5 minutes of inactivity. NOTE: Offset your finger, or use just your nail to push the buttons, so you can see the light in the buttons. AC Adapters for the TPMS Sensor Tool Two AC adapters are included in the TPMS sensor tool kit. The 900 AC adapter is for the battery charger. Use the straight AC adapter to power the TPMS sensor tool when charged batteries are not available. NOTE: ^ The AC adapter does not charge the batteries in the TPMS sensor tool. ^ Remove the batteries from the TPMS sensor tool when using the AC adapter. Using the Battery Charger There are two ways to charge the batteries. The method to use depends on the batteries' state of charge. For brand new or fully discharged batteries: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. The LEDs turn red, and quick charging begins. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed. If the LEDs still do not come on, replace the batteries. ^ If you press the red button while the batteries are charging, the battery discharge mode begins. Press the red button again within 30 seconds, and the charger switches back to its quick charge mode. ^ When the LEDs turn green, the batteries are charged, and the battery charger automatically switches to trickle charge mode. ^ Remove the batteries from the charger when it is not plugged in. For charging batteries when you don't know the state of charge: 1. Connect the AC adapter to the charger (make sure you use the AC adapter with the 90° bend). 2. Insert the batteries into the charger. Make sure you note the polarity (direction) of the batteries. 3. Plug the charger into a power outlet. 4. Press the red button once to start the discharge mode. The LEDs blink red. NOTE: ^ If the LEDs do not come on, check that the batteries are properly installed.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8601 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8602 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8609 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8619 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8620 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8621 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8622 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8623 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8624 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8625 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8626 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8627 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8657 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8658 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8659 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8660 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8661 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8662 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8663 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8664 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Center Mounted Brake Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8665 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions Console Lamp: Diagram Information and Instructions Circuit Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8675 Circuit Schematics Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8676 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8677 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8684 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8694 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8695 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8696 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8697 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8698 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8699 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8700 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8701 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Courtesy Lamp > Console Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8702 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8717 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8718 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8725 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8735 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8736 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8737 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper.

Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8739 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8740 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8741 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8742 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Daytime Running Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8743 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8755 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8756 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8763 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8765 2. Remove the terminal. 3. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE B: 1. Remove the secondary lock from the male terminal half. 2. Remove the secondary lock from the female terminal half.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8773 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8774 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8775 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8776 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8777 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8778 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit.

Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8779 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8780 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Dome Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8781 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8821 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8822 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8839 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8840 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8841 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8842 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8843 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8844 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8845 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8846 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8847 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8856 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8857 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8866 2. Remove the terminal. 3. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE B: 1. Remove the secondary lock from the male terminal half. 2. Remove the secondary lock from the female terminal half.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8874 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8875 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8876 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8877 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8878 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > License Plate Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 8879 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur.

Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions Map Light: Diagram Information and Instructions Circuit Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8892 Circuit Schematics Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8893 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8894 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8901 The connector cavity number is listed next to each terminal on the circuit schematic.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8911 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8912 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8913 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8914 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8915 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8916 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8917 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8918 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Map Light > Component Information > Diagrams > Diagram Information and Instructions > Page 8919 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8942 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8943 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8950 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8960 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8961 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8962 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8963 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8964 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8965 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8966 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8967 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Interior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions > Page 8968 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9018 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9019 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9026 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9028 2.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9036 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9037 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9038 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9039 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9040 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9041 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9042 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9043 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Tail Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9044 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions Trunk Lamp: Diagram Information and Instructions Circuit Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9058 Circuit Schematics Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9059 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9060 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9067 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. EXAMPLE G: 1. Remove the terminal. 2. Go to HOW TO INSTALL NEW TERMINALS. How to Install New Terminals HOW TO INSTALL NEW TERMINALS 1. Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9077 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9078 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9079 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9080 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9081 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9082 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9083 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9084 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Trunk Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9085 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9109 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9110 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9117 The connector cavity number is listed next to each terminal on the circuit schematic. The cavity/terminal shown above is #6.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9127 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9128 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9129 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9130 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9131 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9132 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9133 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9134 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Lighting and Horns > Vanity Lamp > Component Information > Diagrams > Diagram Information and Instructions > Page 9135 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision Power Window Control Module: Technical Service Bulletins Body - Power Window Diagnostics Revision 10-011 March 5, 2010 Applies To: See VEHICLES AFFECTED Service Manual Update: Power Window Goes Up and Reverses On Its Own, Is Slow to Open and Close, or Squeals, Creaks, Clunks, or Clicks BACKGROUND The information in this service bulletin addresses three power window problems that are not currently covered in the service manuals. VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9156 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9157 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Relays and Modules - Windows and Glass > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9158 2. Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel.

Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision Power Window Control Module: Technical Service Bulletins Body - Power Window Diagnostics Revision 10-011 March 5, 2010 Applies To: See VEHICLES AFFECTED Service Manual Update: Power Window Goes Up and Reverses On Its Own, Is Slow to Open and Close, or Squeals, Creaks, Clunks, or Clicks BACKGROUND The information in this service bulletin addresses three power window problems that are not currently covered in the service manuals. VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9191 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9192 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Power Window Control Module > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9193 2. Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

VEHICLES AFFECTED 2003-10 Accord - ALL 2006-10 Civic - ALL 2007-10 Civic Hybrid - ALL 2007-10 CR-V - ALL 2003-10 Element - ALL 2009-10 Fit - ALL 2010 Insight - ALL 2005-10 Odyssey - ALL 2009-10 Pilot - ALL 2006-10 Ridgeline - ALL SYMPTOM 1 When using the auto-up function, the driver's or front passenger's window goes up and then reverses on its own. PROBABLE CAUSE The power window control unit needs to be reset, or the run channel is damaged/dirty. NOTE: Do the power window control unit reset procedure first. If the window still doesn't work, go to Symptom 2. REPAIR PROCEDURE NOTE: You must do the manual reset from the power window switch at the affected window. For example, if you're resetting the front passenger's power window control unit, do it from the front passenger's power window switch, not the driver's power window master switch. 1. Turn the ignition switch to ON (II). 2. Lower the window all the way down with the power window switch. 3. Open the driver's or front passenger's door. NOTE: Do steps 4 thru 7 within 5 seconds of each other. Do these steps a total of four times in a row. These steps clear the control unit's memory. 4. Turn the ignition switch to LOCK (0). Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Window Glass > Front Door Window Glass > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9254 5. Push down and hold the power window switch. 6. Turn the ignition switch to ON (II). 7. Release the powerwindow switch. NOTE: Make sure the auto-up feature doesn't work. If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Windows and Glass > Windows > Window Glass > Front Door Window Glass > Front Door Window Glass Weatherstrip > Component Information > Technical Service Bulletins > Body - Power Window Diagnostics Revision > Page 9255 ^ If the run channel is visibly damaged, replace it, then recheck the window speed. ^ If the run channel looks OK, go to step 3. 3. Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2.

Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

If it does, do steps 4 thru 7 again, paying close attention to the 5-second time limit for up to three more times for each series of steps. 8. Lower the window all the way down with the power window switch. 9. Pull up and hold the power window switch until the window goes all the way up, then keep holding the switch for 1 second. NOTE: Make sure the auto-up/down feature works correctly by lowering and raising the window with the power window switch. If it doesn't work correctly, repeat the manual reset several times, paying close attention to the 5-second time limit. If it still doesn't work, troubleshoot the power window circuit. Then continue with Symptom 2. SYMPTOM 2 The windows are slow to open. PROBABLE CAUSE The run channel is damaged or dirty. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE NOTE: Aftermarket window tinting will also cause the window to move slower and is not covered by the manufacturer's warranty. No repair attempts should be made if the window has aftermarket tinting. 1. Compare the up and down speed of the affected window to another like vehicle: ^ If the speed is the same as the other vehicle, no further troubleshooting is required. ^ If the speed is not the same, remove the door panel and the door glass, then check the window regulator speed. ^ If the speed is the same as it was with the glass in place, replace the window regulator. ^ If the speed is faster without the glass, go to step 2. NOTE: When evaluating regulator performance without the glass, never allow the regulator to travel to the full up position because damage can occur to the regulator. 2. Inspect the visible portion of the run channel for damage.

Reinstall the glass into the door without bolting it to the regulator, then manually slide it through its range of travel and check for excessive resistance: ^ If the resistance is excessive, go to step 4. If the resistance is not excessive, go to step 5. 4. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it, then adjust the run channels and the glass as needed. ^ If the run channel is not pinched, go to step 5. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease. You may also need to clean the portion of the run channel within the door. SYMPTOM 3 During operation, the window squeaks, creaks, clunks, or clicks. REQUIRED MATERIALS Shin-Etsu Grease: P/N 08798-9013 REPAIR PROCEDURE 1. Compare the window's noise level to another like vehicle: ^ If the noise is the same, no repair is needed. Advise the customer that some noise is a normal characteristic. ^ If the noise is different from the other vehicle, go to step 2.

Inspect the run channel for damage. ^ If it is damaged, replace it, then recheck the noise level. ^ If the run channel is not damaged, go to step 3. 3. Remove the door panel. 4. Unbolt the glass from the regulator, then manually slide it through its travel to check for excessive resistance. ^ If the resistance is excessive, go to step 5. ^ If the resistance is not excessive, go to step 6. 5. Clean the run channel using a soapy water solution, then apply Shin-Etsu grease inside the channel. You may also need to clean the portion of the run channel within the door. ^ If the window operates normally after cleaning and applying grease, no further action is required. ^ If the window noise symptoms are still present, go to step 6. 6. Inspect the run channel alignment, both inside and outside the door. Pay close attention just below the door skin; this is a common area for the run channel to be pinched. ^ If the run channel is pinched, replace it and adjust as needed.

A circuit's wires and components are arranged to show current flow, from power at the top of the diagram, to ground at the bottom. Shared Circuits Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring is OK. Connectors Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9433 All in-line and junction connectors are numbered (C725, C416, etc.). Component connectors are not numbered but are identified either by the name of the component if the component only has one connector, or by a capital letter (A, B, C, etc.) if the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo at Vehicle Level Locations that shows the connector's location on the car. The VIEW number refers to an connector view at the Vehicle Level Connector Views that shows the connector terminals, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top left corner of the connector as seen from either of the viewpoints. Except for the DLC (data link connector), disregard any numbers molded into the connector housing. Wires Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in a connector. The number "2" next to the male and female wire terminals at C554, for example, means those terminals join in cavity 2 of connector C554. Power Distribution Schematics Power Distribution Schematics Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9434 Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the vehicle. Refer to the Power Distribution Diagram Set to get a more detailed understanding of how power is supplied to the circuit you're working on. Individual circuit schematics begin with a fuse. So if Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a component in the other circuit. If it works, you know the fuse is good and power is available to the inoperative circuit. Ground Distribution Schematics Ground Distribution Schematics This sample Ground Distribution schematic shows all of the components that share the same ground point.

The cavities are numbered starting from the upper left, looking at the male terminals from the terminal side or looking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same. All actual cavities are numbered, even if they have no wire terminals in them. NOTE: Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four end terminals are molded into the corners of the connector face. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9441 The connector cavity number is listed next to each terminal on the circuit schematic.

However, not all terminals for all connectors are available. Refer to the labels on the lids of the repair kits for replacement terminal availability. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. Before you begin, inspect the wire you are about to repair for damage and length. Make sure the wire will be long enough to make a terminal repair without stretching it when you reinstall the terminal in the connector. If the wire is too short, or if access to the connector is too restricted to make a terminal repair, you may need to install a pigtail terminal (a short length of wire with a factory-crimped terminal on it). Refer to HOW TO INSTALL PIGTAIL TERMINALS. Removing the Terminal Use the tools from Pin Tool Set. First, check the connector that you are about to repair. - If it has a secondary terminal lock, go to Connectors With a Secondary Lock. A secondary lock, found on most connectors on some models, is an additional locking device on the connector housing as a backup for the primary lock on the terminal. - If the connector does not have a secondary lock, go to Connectors Without a Secondary Lock. Connectors With a Secondary Lock All examples are shown with the connector lock facing up. The illustrations are examples of the secondary terminal locks; however, the connector you are repairing may vary in size. Identify the connector by the type of secondary lock, not by the number of terminal cavities. EXAMPLE A: 1. Release the secondary lock.

Carefully match the old terminal with a new one from the terminal repair kit. Choose the correct replacement terminal based on the wire size range the terminal will accommodate. NOTE: If the replacement terminal quantities are low, reorder them by using the terminal part number listed on the inside lid of the terminal repair kit. Replacement terminals are available through your parts department using normal parts ordering procedures. 2. Depending on the size of the wire you are repairing, use the proper size slot in the crimping tool. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9451 3. Strip the insulation off the end of the wire so the wire fits in the new terminal as shown. (If the wire has a wire seal, replace it with a new one from the kit.) NOTE: After stripping the end of the wire, make sure you did not cut any wire strands. If you did, cut the wire off even with the insulation, and strip it again. 4. Position the terminal in the crimping tool slot with the solid portion of the terminal toward the anvil and the open section toward the former. 5. Insert the wire in the terminal to the position shown in step 3. 6. Squeeze the tool with both hands until the stops make contact. 7. Crimp the insulation crimp. - If you do not have a wire seal, then use the next larger size crimp slot. Position the crimping tool over the insulation crimp section of the terminal, then squeeze the tool with both hands until the stops make contact. - If you have a wire seal, position the insulation crimp in the 5.5 crimping slot, then carefully squeeze the crimp closed until its ends are touching and making a full-circle shape. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9452 8. Inspect the quality of the wire crimp. If it has any of the following NO GOOD crimps, cut it off and start over. 9. Insert the terminal into the connector. Make sure the wire seals are pushed all the way into the connector. Lightly pull on the wires to make sure the terminal is locked into place. 10. Close or insert the secondary terminal lock, if applicable, and reconnect the connector. How to Install Pigtail Terminals HOW TO INSTALL PIGTAIL TERMINALS Pigtail terminals (short pieces of wire with a factory crimped terminal) are used when the wire is too short or when access to the connector is too restricted to make a terminal repair. NOTE: To replace just a connector terminal, go to How to Replace Connector Terminals. IMPORTANT SAFETY INFORMATION: On some models, the SRS wires are in a separate harness. If the SRS harness is damaged, replace the harness; do not repair it. On other models, wire harnesses include yellow SRS wires. If any SRS wire is damaged, replace the entire harness; do not repair it. 1. Remove the damaged or faulty terminal from the connector. Use the proper removal tool from Pin Tool Set. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9453 2. Cut off the wire about an inch back from where it connects to the damaged or faulty terminal, then strip about half of the insulation off that piece. This will be used to size the wire end of the replacement pigtail terminal. NOTE: If you are not sure of the wire size, start with a large enough hole on the stripper that will not nick or cut off any strands of wires. 3. Select a pigtail terminal that matches the original wire at both ends (same kind of terminal and same diameter bare wire). 4. Select the smallest splice connector (yellow, pink, or blue) that will fit onto the stripped end of the original wire. 5. Insert the pigtail terminal into the connector cavity; push it in until it locks in place. 6. Lay the pigtail and the original wire side-by-side, and cut off both ends at once. If you are making more than one splice, do not cut each pigtail at the same location; the resulting "lump" of splice connectors would interfere with rewrapping the harness. Instead, cut the first pigtail close enough to the terminal so you will have room to make each remaining cut about 20 mm (3/4 inch) farther down on the next pigtail. 7. If you are using a yellow splice connector, strip about 6 mm (1/4 inch) of insulation off the ends of both wires. If you are using a pink or blue splice connector, strip off about 8 mm (5/16 inch) of insulation. NOTE: If you nick or cut off any strands of wire, try again with the next larger size hole on the stripper. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9454 8. Put the splice connector in the proper size slot in the Crimper Tool, slide it to one end (where the flare begins), and close the crimper handles far enough to hold it in place. To release the ratchet mechanism at any point after the first click, squeeze the handles slightly and push the release lever, then let the handles open. 9. Insert one of the bare wires into the splice connector end that is in the crimper jaws. Push the wire all the way into the splice connector, and squeeze the crimper handles. Keep squeezing until the jaws touch, and hold it at that position until the ratchet clicks again. 10. Crimp the other wire in the same way into the other end of the splice connector. 11. After crimping, gently pull on the wires in the opposite directions to make sure they are secure in the connector. 12. Separate the other wires in the harness from the repaired wire(s), and shield them with nonflammable material. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9455 13. Plug in the heat gun, and turn it on. Start at the middle of the splice connector, and move the gun toward the ends as the tube shrinks. Apply heat evenly by rotating the curved heat spreader around the splice connector. Shrinking is complete when a small amount of sealant appears at each end of the tube. NOTE: Be careful when working with the high heat produced by the heat gun. Pigtail Terminal Selection Chart PIGTAIL TERMINAL SELECTION CHART Select the proper size pigtail terminal by matching the replacement terminal part number and the wire size being repaired to the corresponding pigtail terminal part number. Then use the color (size) splice connector listed. In some instances you may also have to match the wire seal style to select the proper pigtail terminal. Pigtail terminals are available through your parts department, in quantities of 10, using normal parts ordering procedures. Checking For Poor Fit Terminals CHECKING FOR POOR FIT OF TERMINALS Loose terminal fit can cause a number of intermittent problems in electrical circuits. By using the Terminal Inspection Feeler Tool Set you can inspect the terminal fit between the two matching connectors without removing the terminals from the connector body. 1. Find the terminal tool that best matches the male terminal in the mating connector. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9456 2. Insert the terminal tool into the female terminal, and then remove the terminal tool. NOTE: Make sure you do not select a terminal tool that is larger than the mating male terminal because it would spread the female terminal and cause a loose fit. 3. Compare the drag to the other terminals in the connector. If the drag is less, replace the terminal with a replacement terminal from the appropriate terminal repair kit. Five-Step Troubleshooting Five-Step Troubleshooting 1. Verify The Complaint Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. 2. Analyze The Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power source through the circuit components to ground (certain circuits contain a "How the Circuit Works" Diagram set). Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the same fuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes. 3. Isolate The Problem By Testing The Circuit Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. 4. Fix The Problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. 5. Make Sure The Circuit Works Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur. Test Equipment Test Equipment CAUTION: Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Test Light and DVOM On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12 volt bulb with a pair of leads attached. After grounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at the point being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM). If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM). In the "OHMS" range, the DVOM will measure resistance between two points along a circuit. Low resistance means good continuity. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9457 Diodes and solid-state devices in a circuit can make a DVOM give a false reading. To check a reading, reverse the leads, and take a second reading. If the readings differ, the component is affecting the measurement. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Jumper Wire Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a set of test leads. It should have a five ampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse. To order any test equipment shown, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required Special Tools and Equipment Service Bulletin. Troubleshooting Precautions Troubleshooting Precautions Before Troubleshooting 1. Check the main fuse and the fuse box. 2. Check the battery for damage, state of charge, and clean and tight connections. CAUTION: Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes. - Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring. While You're Working 1. Make sure connectors are clean, and have no loose terminals or receptacles. 2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001. 3. When connecting a connector, push it until it "clicks" into place. CAUTION: Do not pull on the wires when disconnecting a connector. Pull only on the connector housings. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9458 - Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-mega ohm or higher impedance digital multimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result. Troubleshooting Tests Troubleshooting Tests Testing for Voltage When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Connect one lead of the test light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC volts range, and connect its negative lead to ground. 2. Connect the other lead of the test light or DVOM to the point you want to check. 3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present). Testing for Continuity When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = an open). 1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range. 2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test. 3. Connect the other lead to the other end. Honda Civic Workshop Manual (L4-1.8L CNG (2008)) Honda Workshop Manuals > Wiper and Washer Systems > Wiper Motor > Component Information > Diagrams > Diagram Information and Instructions > Page 9459 4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity. Testing for Voltage Drop Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. Circuits must be operating when checking voltage drop. 1. Place the digital volt/ohmmeter (DVOM) in the appropriate DC volts range. Connect the positive lead to the end of the wire (or to the connector or switch) closest to the battery. 2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch). 3. Turn on the components in the circuit. 4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than one volt indicates a problem. Check the circuit for loose, dirty, or bent terminals. Testing for a Short with a Test Light or DVOM 1. Remove the blown fuse and disconnect the load. 2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage is present. You might have to turn the ignition switch to ON; check the schematic to see. 3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about six inches apart while watching the test light or DVOM. 4. Where the test light goes off, or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point. NOTE: Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).
