Clearing Codes
Turn ignition off. Disconnect negative battery cable for a minimum of 20 seconds. Code(s) are now cleared. Reconnect battery cable.
NOTE:
Turn ignition off before disconnecting or reconnecting battery power to ECM. When battery power is disconnected from ECM to clear codes, computer memory will be erased. A change in vehicle performance and driveability may be noted while ECM recalibrates for current driving conditions.
