Clearing Codes

CAUTION: Ensure ignition is off when disconnecting or reconnecting power to ECM.
  1. After performing repairs, clear ECM memory of stored trouble codes. To clear memory, turn ignition off. Remove 60-amp MAIN fuse from fuse block, located in left front corner of engine compartment, for at least 10 seconds. Replace fuse.
  2. Trouble codes can also be cleared by disconnecting negative battery cable. However, other memory functions (clock, radio, etc.) will then require resetting.
NOTE: Codes will also erase if problem does not reoccur within 50 engine starts.
