System Operation - Approach Detection

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

The approach detection feature is used to passively activate the illuminated entry feature while approaching the vehicle. Illuminated entry includes ramping up the illumination of the vehicles parking lamps.

Once illuminated entry is activated, the BCM sends a message over the LIN circuit to both adaptive front lighting modules (one mounted on each headlamp) and to the rear lamp fade control module.

For front parking lamps, when the adaptive front lighting module receives the illuminated entry message from the BCM, the adaptive front lighting module ramps up the front parking lamps.

For rear parking lamps, when the rear lamp fade control module receives the illuminated entry message from the BCM, the rear lamp fade control module supplies a PWM voltage to the each rear and liftgate parking lamps to ramp up illumination.
