Clearing Diagnostic Trouble Codes

"Current" DTCs (21-25) remain stored by the BCM, and are displayed in the Diagnostic Mode, as long as the BCM detects the fault. "History" DTC (31-35) can be cleared by depressing and holding the door unlock switch for 4 seconds while the BCM is in the Diagnostic Mode. After 4 seconds, an Audible Warning tone will sound 3 times confirming that the DTC(s) have been cleared.

To clear "History" DTCs on vehicles without power door locks, backprobe with a fused jumper from BCM connector C1 terminal "D" to ground for 4 seconds while in the Diagnostic Mode. After 4 seconds, an Audible Warning tone will sound 3 times confirming that the DTC(s) have been cleared.
