Theory Of Operation

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

The Body Control Module (BCM) provides voltage to the Universal Garage Door Opener (UGDO) located in the Vanity Mirror. When the anti-theft alarm is active, the BCM disables the power feed to the UGDO.
