Powertrain Control Module Reset Procedure/Clearing Diagnostic Trouble Codes (All Models)

NOTE: Some models have an anti-theft code built into radio circuit. Clearing codes cancels clock and radio settings; make note of anti-theft code and station presets before beginning reset procedure. After PCM reset, radio will not operate until anti-theft code is entered.

NOTE: If service check connector is connected and no DTC is stored in PCM, MIL will remain on when the ignition is turned on.

To reset Powertrain Control Module (PCM) (clear DTCs), use Honda PGM tester or OBD-II scan tool following manufacturer's instructions. After DTCs are cleared and PCM is reset, remove SCS service connector, if connected. Disconnect Honda PGM Tester or scan tool from DLC. DTCs can also be cleared by turning ignition off and removing BACK UP (RADIO) fuse (7.5-amp) from underhood fuse/relay block (located next to battery). On all models, leave fuse out for at least 10 seconds to reset PCM.
