Clearing Trouble Codes

Erasing Diagnostic Trouble Codes (DTC's)

Diagnostic trouble codes can be cleared from the memory two ways:
- The DRB III scan tool
- Power to the BCM can be disconnected for ten minutes by disconnecting the battery negative remote cable.

If the scan tool is to be used, refer to the proper LH Body Diagnostic Procedures.

CAUTION: Fault code 26 can be created if the in-car sensor thermistor is disconnected while the BCM is operating. This can happen by disconnecting connectors from the BCM or the ATC Control Head when the battery is connected (even if the ignition switch is OFF). To correct, clear the fault code 26 from the BCM.
