PCM RESET PROCEDURE/CLEARING DTCS
Note. Before disconnecting battery or removing 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, leave radio on at least one hour, then enter code correctly. Any time radio power is lost, pre-selected radio stations will have to be reset. For more information, see 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 fuse. Turn ignition off. Remove BACK UP (7.5-amp) fuse from underhood fuse/relay block. Leave fuse out for at least 10 seconds. Reset radio anti-theft code, pre-selected radio stations and clock.
