Non-Networked Illumination Operation

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 BCM calculates the correct intensity for the dimmable non-networked illumination sources based on the ambient light intensity input from the light sensor and the requested illumination intensity level input from the dimmer switch (integral to the headlamp switch). The BCM provides a PWM voltage to all non-networked illumination sources.

The non-networked, non-dimmable switches are illuminated whenever the accessory delay relay is energized with the ignition switch ON or OFF.
