ECM Reset Procedure/Clearing Codes

WARNING: This page is about a different car, the 1995 Honda Prelude, 1995 Honda Odyssey, and 1995 Honda Accord. However, it is still accessible from the selected car via links, so may be relevant.

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

To reset Engine Control Module (ECM) (clear codes), remove BACK UP (7.5-amp) fuse (CLOCK/RADIO (10-amp) fuse on Prelude) from underhood fuse/relay box. Leave fuse out for 10 seconds to reset ECM.
