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 ECM (clear codes), remove CLOCK/RADIO fuse from underhood fuse/relay block. Leave fuse out for 10 seconds to reset ECM.
