Pcm Reset Procedure/Clearing DTCS
NOTE:
Before disconnecting battery or removing specified fuse, obtain anti-theft code for radio from vehicle owner. After battery or fuse is reconnected, CODE will appear on radio display. Enter 5-digit code to restore radio operation. On CR-V, if code is entered incorrectly 3 times, ERR-E will display, leave radio on at least one hour, then enter code correctly. Except CR-V, if correct anti-thief code is not entered after 10 attempts, leave radio on at least one hour, then enter code correctly. If radio code is unavailable, radio must be returned to manufacturer to unlock. Any time radio power is lost, pre-selected radio stations will have to be reset. For specific setting information, see vehicle owner's manual.
Powertrain Control Module (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 specified fuse for 10 seconds from fuse/relay box. Obtain radio anti-thief code and record radio presets before removing fuse. On all models, turn ignition off. On Accord and Odyssey, remove No. 13 CLOCK BACKUP (7.5-amp) fuse from passenger-side underdash fuse/relay box. On Civic and CR-V, remove No. 19 BACK UP (7.5-amp) fuse from underhood fuse/relay block. On Prelude, remove No. 13 CLOCK RADIO (7.5-amp) fuse from underhood fuse/relay block. After replacing fuse, reset radio anti-theft code, pre-selected radio stations and clock.
