How to Reset the ECM/PCM

How to Reset the PCM
You can reset the PCM in either of 2 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 (7.5 A) (A) from the passenger's under-dash fuse/relay box (B) for 10 seconds.
