Headlight Leveling Circuit Description Europe

Voltage is supplied to the headlamp leveling switch and the headlamp leveling actuator motors through circuit 10 with the headlamp switch in the HEAD position. Ground is provided at all times to the headlamp leveling switch through G200, circuit 650, the leveling jumper resistor, and the headlamp leveling switch signal circuit.

The headlamp leveling switch provides 4 headlamp leveling positions. When a position is selected, a different resistance value is provided to the headlamp leveling actuator motors. The actuator motors have an internal motor logic driving a motor to move the headlamps based on the resistance it receives. Ground is provided through circuit 150 (left) and 250 (right) to the actuator motors at all times.
