B2874 RAM Description
The Body Control Module (BCM) receives a communication network message from the Steering Column Control Module (SCCM) requesting turn signal lamp illumination. When this bus message is received, the BCM provides a pulsed voltage output through the rear turn signal control circuit. The rear turn signal control circuit connects to the Turn Signal Lamps. The Diagnostic Trouble Code (DTC) sets when the Body Control Module (BCM) detects a low condition on the Right Rear Turn Lamp Driver circuit.
