Theory Of Operation

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

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 Right and Left Rear Park Lamp Control circuit to the Park Lamps. A ground path for the lamps is present through the harness.
