Headlamps

Voltage is applied at all times to the Headlamp Switch through the HEADLAMP Circuit Breaker and CKT 242. With the Headlamp Switch ON, voltage is applied to the coil of the Headlamp Relay which is permanently grounded to G201. The coil is energized and the contacts close providing voltage to the Headlamp Dimmer Switch. When the Headlamp Dimmer Switch is in the LO position, the LH and RH Low Beam filaments light. When the Headlamp Dimmer Switch is in the HI or FLASH position, the LH and RH High Beam filaments light. When the Ignition Switch is in RUN and the Ambient Light Sensor indicates darkness, the Lamp Control Module provides voltage through the Headlamp Dimmer Switch to the Headlamps.
