Diagnostic Trouble Codes (DTCs)

The Remote Control Door Lock Receiver (RCDLR) sends door locking command (and remote alarm command, if equipped) messages to the Body Control Module (BCM) through the RFA link. The BCM sets DTC 89 if the RFA link circuit 6377 is shorted to B+ or ground. Refer to Body Control Module Diagnostic Information in Body Control System for more information. Testing and Inspection
