B0507 CADILLAC DescriptionThe Body Control Module (BCM) provides control for the LH DRL relay circuit. The BCM grounds the Left Daylight Running Lamp (DRL) relay control circuit in order to energize the LH DRL relay and turn ON the LF turn signal This allows the LF turn signal to be used for DRL and approach lighting functions. The BCM monitors the voltage level on the LH DRL relay control circuit. When the BCM commands the relay ON, the voltage level on the LH DRL relay control circuit should be low. When the relay is OFF, the voltage on the LH DRL relay control circuit should be high. If the BCM detects a voltage level other than expected, a malfunction is present and a Diagnostic Trouble Code (DTC) will set.
