Without OBD II
1. Turn the ignition switch OFF.
2. Remove the No. 39 BACK UP. RADIO fuse (7.5 A) from the under-hood fuse/relay box for 10 seconds to reset the PCM.
NOTE: Disconnecting the No. 39 BACK UP. RADIO fuse also cancels the radio anti-theft code, preset stations and clock setting. Get the customer's code number, and make note of the radio presets before removing the fuse so you can reset them.
