ECM Reset Procedure/Clearing Codes

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.
