Use the Diagnostic Trouble Code (DTC) tables in order to locate a faulty circuit or component through the process of elimination. The Body
Control Module (BCM) performs a continual self diagnosis on certain control functions. A DTC will set when a malfunction is detected by the
BCM. The BCM will not turn the SERVICE ENGINE SOON Malfunction Indicator Lamp (MIL) lamp ON.
