The BCM provides a Pulse Width Modulated (PWM) voltage output through the left rear park lamp control circuit. The control circuit connects to the LED Park Lamps. 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 .
