Clearing Trouble Codes
CAUTION:
Ensure ignition is off when disconnecting or reconnecting power supply to ECM.
- After repairs are performed, clear ECM memory of all stored trouble codes. To clear memory, turn ignition off and remove ECM fuse (30A) from engine compartment fuse block for at least 30 seconds. Replace fuse.
- After clearing trouble codes, confirm that system will operate in closed loop mode and ensure that CHECK ENGINE light functions properly.
NOTE:
Trouble codes can also be cleared by disconnecting vehicle battery. However, other memory functions (clock, radio, etc.), will require resetting.
