Theory Of Operation

WARNING: This page is about a different variant/trim than selected.

The Body Control Module (BCM) receives the input from the Left Multi-function Switch requesting park lamp illumination. The BCM provides a Pulse Width Modulated (PWM) voltage output through the Park Lamp Driver circuit. The control circuit connects to the 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 PARK LAMPS .
