Headlamp Switch: Description and Operation

The headlamp switch is a multi-position switch.
^ The positions include OFF, PARK, and HEAD.
^ With the headlamp switch in the PARK position (first detent), a signal is supplied to the LCM which powers the front parking lamps, the tail lamps, the rear side marker lamps, and the license lamp.
^ With the headlamp switch in the HEAD position, power is supplied to the headlamps through the LCM. The multi-function switch input tells the LCM to turn on low beams or high beams.
