How to Reset the ECM/PCM

You can reset the ECM/PCM in either of two ways:
- Use the OBD II scan tool or Honda PGM Tester to clear the ECM/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.6 ECU (ECM/PCM) (15 A) fuse (A) from the under-hood fuse/relay box (B) for 10 seconds.
