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 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 (7.5 A) fuse (A) from the passenger's under-dash fuse/relay box (B) for 10 seconds.

How to End a Troubleshooting Session (required after any troubleshooting)
1. Reset the PCM as described above.
2. Turn the ignition switch OFF.
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.
