Without Scan Tool

To clear the codes from the memory of the Electronic Control Module (ECM), either to determine if the malfunction will occur again or because repair has been completed, the ECM power feed must be disconnected for at least thirty (30) seconds. To remove power from the ECM, remove the "TAIL" fuse, located in the junction block OR if working underhood, the 40A fusible link "C" (green) in the fuse/relay box on the left front fender apron can be removed. The negative battery terminal may also be disconnected, but removal of the 40A fusible link or the negative battery terminal will erase memory in the clock and/or radio.

CAUTION: To prevent ECM damage, the key must be "OFF" when disconnecting or reconnecting ECM power.
