Powertrain Control Module Reset Procedure
CAUTION:
Before disconnecting battery, obtain anti-theft code for radio. After battery is reconnected, the word CODE will appear on radio display. Enter 5-digit anti-theft code using select buttons and radio will begin working. If code is entered wrong 10 times, leave radio on at least one hour and enter code correctly. Any time radio power is lost, pre-selected radio stations will have to be set. For more information, see owner's manual.
PCM can be reset, which clears DTCs, using a Honda PGM tester or OBD-II scan tool following manufacturer's instructions.
DTCs can also be cleared by removing BACK UP (RADIO) (7.5-amp) fuse from underhood fuse/relay box for 10 seconds. After replacing fuse, reset radio anti-theft code, pre-selected radio stations and clock.
