Headlamp Alignment Actuator - Description
DESCRIPTION
The headlamp leveling motor (1) is located on the rear surface of each front lamp unit on vehicles equipped with the headlamp leveling system, which is available only in certain export markets where it is required equipment. The motor is encased within a molded plastic housing and is secured by an integral wedge-type mounting flange (2) 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 (4) on its upper rearward surface and a plastic pushrod with a ball formation (3) on its free end extends from the motor mounting flange. 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 headlamp and dash wire harness.
The headlamp leveling motor cannot be repaired and, if ineffective or damaged, the entire motor unit must be replaced.
