Body Control Module (BCM)

DTC List:

The Body Control Module (BCM) stores DTCs as current or history codes. If the BCM detects a system malfunction, the BCM will only store a DTC that corresponds to that particular malfunction. The BCM will not send a message to the Instrument Panel Cluster (IPC) to display a message. If a current Diagnostic Trouble Codes (DTCs) is stored and the fault is no longer present, some DTCs will remain current until the next ignition cycle. Other DTCs will go history when the fault is no longer present and does not require an ignition cycle. History DTCs are intermittent malfunctions and must be diagnosed differently than current DTCs.
