The Body Control Module (BCM) receives the input from the headlamp switch requesting park lamp illumination. The BCM provides a Pulse Width Modulated (PWM) voltage output through the Front Right Side Marker control circuit. The control circuit connects to the LED Park Lamps and Right Front Side Marker Lamp. A ground path for the lamps is present through the harness to the body sheet metal. For additional information on the Park Lamps operation, refer to OPERATION .
