Headlamps - Canada

The headlamps may be turned on two different ways. First, when the driver places the headlamp switch in the HEAD position, for manual operation. Second, with the headlamp switch placed in the OFF position, for Automatic Lamp Control (ALC). During low light conditions the Daytime Running Lamps (DRL) control module will illuminate the automatic headlamps.

The low beam headlamps will always illuminate whenever the headlamp switch is in the HEAD position or the ALC are on, regardless of the headlamp dimmer switch position. The high beams will illuminate only when low beam headlamps are illuminated and the headlamp dimmer switch is in the HIGH position.

During manual operation the fusible link Z, supplies battery voltage to the headlamp switch. When the headlamp switch is moved to the Head position, battery positive voltage is supplied to the low beam headlamps and the headlamp dimmer switch. When the headlamp dimmer switch is in the HIGH position, battery voltage is then supplied to the high beam headlamps.

G 105 supplies the ground to the right headlamps.
