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. If code is entered incorrectly 3 times (on CR-V, ERR-E will display), leave radio on at least one hour, then enter code correctly. If correct anti-thief code is not entered after 10 attempts, radio will lock and 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 owners 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, remove No. 13 CLOCK BACKUP (7.5-amp) fuse from passenger-side underdash fuse/relay box. On Civic and CR-V, remove No. 47 BACK UP (7.5-amp) fuse from underhood fuse/relay block. On Oasis and Odyssey, remove No. 39 BACK UP (7.5-amp) fuse from underhood fuse/relay block. On Prelude, remove No. 43 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.
