Clearing Diagnostic Trouble Codes

Current DTCs (21 to 25) remain stored by the body control module (BCM) and are displayed in the diagnostic mode as long as the BCM detects the fault. Once the fault is corrected, the current DTCs are cleared by the BCM. To clear history DTCs (31 to 35) press and hold the door unlock switch for 4 seconds while the BCM is in the diagnostic mode. The BCM will sound three audible warning tones to confirm that the DTCs are cleared.

To clear BCM history DTCs on vehicles without power door locks, backprobe with a fused jumper from BCM connector C1 terminal D to ground for 4 seconds. The BCM will sound three audible warning tones to confirm that the history DTCs have been cleared.
