Circuit/System Description

The Lighting Control Module supplies battery voltage to the LED lamps located under the outside rearview mirrors and each door handle assembly for approach lighting. When the unlock function is commanded on the keyless entry transmitter, a serial data message is sent to the Lighting Control Module. If the keyless entry transmitter is detected within 3 meters of the vehicle, a serial data message is sent to the Lighting Control Module to illuminate the exterior courtesy lamps. The Lighting Control Module responds to this input by illuminating the outside rearview mirror and door handle assembly courtesy lamps (if equipped) via the Approach Lighting feature. Approach Lighting will be disabled if the vehicle battery is low, the ignition is ON, the keyless entry transmitter is left within 5 meters of the vehicle for an extended period of time, the keyless entry transmitter is left inside the vehicle with all doors closed, or the vehicle has been parked for extended period of time with no remote key use. Exterior courtesy Lamps settings can be customized through the vehicle infotainment system. Exterior Courtesy Lamps will be disabled under all conditions if the vehicle is in service mode.
