Under-dash Fuse / Relay Box Showing ECM Back-up Fuse:

1. Turn the ignition off. Make sure the Service Check Connector is NOT jumped (If the Service Check Connector is jumped, the MIL will stay on).
2. Remove the CLOCK/RADIO fuse (10A) from the under-hood relay box.
3. Wait 10 seconds for the PGM-FI ECM to clear its memory, and reinstall the CLOCK/RADIO fuse.

NOTE:
- Removing the CLOCK fuse also cancels the radio presets and the clock settings. Make a note of the radio presets before removing the fuse so you can reset them.
- The radio may have a coded anti-theft circuit. Be sure you get the customer's code number before removing the CLOCK fuse.
