Dimmer Switch

WARNING: This page is about a different car, the 2014 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

The dimmer switch is a momentary contact switch that is integral to the headlamp switch. When the dimmer switch is pressed, the requested illumination level is sent to the BCM  over a LIN  circuit.
