Headlight Doors

Battery Positive voltage is applied from the HDLP circuit breaker in the instrument panel fuse block to both the coil and switch side of the ALC HDLP relay 44. When the BCM receives this signal it will apply a ground to the coil side of the ALC HDLP relay 44. This energizes the relay, closing the switch, and applies battery positive voltage to the headlamp switch and to the headlamp opening door actuator control module. This actuator allows battery positive voltage from the HDLP MOT LH fuse and HDLP MOT RH fuse in the underhood electrical center to be applied to the headlamp opening door assemblies. The ground circuit is applied from G102.
