Non-Networked Illumination Operation

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

Based on the ambient light level input from the light sensor and the requested illumination dimming level input from the dimmer switch, the BCM calculates the correct dimming level for the non-networked illumination sources. The BCM provides a pulse-width modulated voltage to all non-networked illumination sources on two circuits.

The start/stop switch is non-networked to the BCM but integral to the GSM and cannot be serviced separately.
