Body Control Module: Reading and Clearing Diagnostic Trouble Codes
Trouble Codes - Current & History
The Body Control Module (BCM) stores DTCs as current or history DTCs. If the BCM detects a malfunction, the BCM stores a DTC that corresponds
to that particular malfunction. The BCM does not send a message to the Instrument Panel Cluster (IPC) to display a message, such as turning on a
warning indicator lamp. If the BCM stores a current DTC and the malfunction is no longer present, some DTCs will remain current until the next ignition
cycle. Other DTCs change from current to history without requiring a new ignition cycle when the fault is no longer present. History DTCs are
intermittent malfunctions and must be diagnosed differently than current DTCs. Refer to Intermittent and Poor Connections for more information.
