Principles of Operation
PRINCIPLES OF OPERATION
NOTE: The stoplamps are powered directly from the stoplamp switch, not from the lighting control module (LCM).
The stoplamps are supplied voltage from the stoplamp switch. When the brake pedal is applied, the internal switch closes and voltage is supplied directly
to the high mounted stoplamp and the multifunction switch, which then routes the voltage to the rear stoplamps.
