DTCs Current and History
The
Body Control Module (SBM) stores DTCs as current or history codes. If the SBM detects a system malfunction, the SBM will only store a DTC that corresponds to that particular malfunction. The SBM will not send a message to the IPC to display a message. If a current DTC is stored and the fault is no longer present, some DTCs will remain current until the first 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. Refer to
Intermittents and Poor Connections.
