Fuel and Emissions Systems: Diagnosis Honda Insight ZE2 рестайлинг

If you can't duplicate the DTC

Some of the troubleshooting requires you to reset the PCM and try to duplicate the DTC. If the problem is intermittent and you can't duplicate the DTC, do not continue through the procedure. To do so will only result in confusion and possibly, a needlessly replaced PCM.

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 (see PCM IDLE LEARN PROCEDURE ); CKP pattern learn procedure; test-drive to set readiness codes to complete (see HOW TO SET READINESS CODES ).

DTC Clear

1. Clear the DTC with the HDS while the engine is stopped.
2. Turn the ignition switch to LOCK (0).
3. Turn the ignition switch to ON (II), and wait 30 seconds.
4. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.

How to End a Troubleshooting Session (required after any troubleshooting)

1. Reset the PCM with the HDS.
2. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-513173-S16164063582012110700000) ).
3. Turn the ignition switch to LOCK (0).
4. Disconnect the HDS from the DLC. NOTE: The PCM is part of the immobilizer system. If you replace the PCM, you must use the HDS to instruct the new PCM and the immobilizer-keyless control unit to recognize each other's unique serial code.

How to Troubleshoot Circuits at the PCM Connectors

Note. The PCM overwrites data and monitors the EVAP system for about an hour after the ignition switch is turned to ACC (I) or to LOCK (0). Jumping the SCS line after turning the ignition switch to ACC (I) or LOCK (0) 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. Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C have symbols (A=[], B=↑ , C=o) embossed on them for identification.
3. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check.
4. Connect one side of the patch cord terminals (A) to a commercially available digital multimeter (B), and connect the other side of the terminals (C) to a commercially available banana jack (Pomona Electronics Tool No. 3563 or equivalent) (D).
5. Gently contact the pin probe (male) at test port from the terminal side. Do not force the tips into the terminal test ports. 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. 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.

DTC Troubleshooting Index

Symptom Troubleshooting Index

When the vehicle has one of these symptoms, check for a diagnostic trouble code (DTC) with the HDS. If there is no DTC, do the diagnostic procedure for the symptom, in the sequence listed, until you find the cause.
