Left Rear Lamp Diagnostic Line - Circuit Short To Ground

Cause of DTC

When the ignition is on, the Body Control Module (BCM) provides a 12 volt signal on the Left and Right Front Lamp Fault Sense circuit to the Front Lamp Assemblies and to the Left and Right Stop Lamp Fault Sense circuit to the Tail Lamp Assemblies. When the Left or Right Turn Lamp is activated, an internal driver in the Lamp Assemblies will pull the Fault Sense circuit voltage signal low (below 6 volts), in sequence with the Turn Lamp flash. When the Turn Lamps are Off, the BCM will maintain the Fault Sense circuit high (above 8 volts).
