Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pcm Reset Procedure/Clearing Codes
To reset Powertrain Control Module (PCM) (clear codes), use Honda PGM tester or OBD-II scan tool following manufacturer's instructions. Codes can also be cleared by turning ignition off and removing BACK UP (7.5-amp) fuse from underhood fuse/relay block (located next to battery). Leave fuse out for at least 10 seconds to reset PCM. Remove SCS service connector, if connected. Disconnect Honda PGM tester or scan tool from DLC.
