Theory Of Operation

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Once the BCM is informed that the vehicle is in reverse, it provides a Pulse Width Modulated (PWM) voltage output through the backup lamp driver circuit. The driver circuit connects to the Backup Lamp. A ground path for the lamps is present through the harness to the body sheet metal. For additional information on the Backup Lamps operation.
