Theory Of Operation

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The courtesy lamp is a LED with a built in circuit board. The BCM controls the operation and sends a bus message to the Door Module to turn the lamp on or off.
