Headlamp Alignment Actuator: Description and Operation
Headlamp Alignment Actuator - Description
DESCRIPTION
The headlamp leveling motor is located on the rear upper surface of each front lamp unit on vehicles equipped with the headlamp leveling system, which
is available only in certain markets where it is required equipment. The motor is encased within a molded plastic housing and is secured by an integral
wedge-type mounting boss to a keyed flange on the back of the front lamp unit housing. A rubber seal around the circumference of the mounting boss
seals the motor to the lamp housing.
The outside of the motor housing features an integral molded connector on its rearward surface, a hex-headed adjusting screw extends from the top of the
housing, and a plastic pushrod with a ball formation on its free end extends from the motor mounting boss. Within the motor housing is a 12-volt Direct
Current (DC) servo motor, an electronic controller board that includes the motor logic circuits, and an integral screw-drive transmission. The headlamp
leveling motor is connected to the vehicle electrical system through a dedicated take out and connector of the front lamp unit wire harness.
The headlamp leveling motor is serviced as a unit with the front lamp unit. The motor cannot be repaired and, if ineffective or damaged, the entire front
lamp unit must be replaced.
