Dimmer Switch

The instrument panel dimmer switch is a single detent rocker style switch with 2 inputs to the BCM  to control all dimmable interior illuminated components. When the instrument panel dimmer switch is pressed up to increase the dimmable backlighting intensity or down to decrease the dimmable backlighting intensity, a ground signal is routed to the BCM  . Based on the ground signal input from the instrument panel dimmer switch, the BCM  sends a message over the network to the modules with dimmable backlighting, indicating the backlighting intensity level, and provides voltage to the non-networked dimmable illumination sources.
