Theory Of Operation
The Body Control Module (BCM) receives the input from Left Multi-function Switch requesting park lamp illumination. The BCM provides a voltage output through the license plate lamp control circuit. The control circuit connects to the License Plate Lamps, which are part of the Park Lamp lighting system. A ground path for the lamps is present through the harness to the body sheet metal.
