Clearing Diagnostic Trouble Codes

How to Reset the PCM

You can reset the PCM in either of two ways:
- Use the OBD II scan tool or Honda PGM Tester to clear the PCM's memory.
See the OBD II scan tool or Honda PGM Tester user's manuals for specific instructions.




- Turn the ignition switch OFF, and remove the No.13 CLOCK BACKUP fuse (7.5A) (A) from the passenger's under-dash fuse/relay box (B) for 10 seconds.

NOTE: After resetting the PCM, do the PCM idle learn procedure

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

1. Reset the PCM as described above.
2. Do the PCM idle learn procedure.
3. Disconnect the OBD II scan tool or Honda PGM Tester 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 Honda PGM Tester.
