Headlamp Alignment Actuator: Description and Operation
Headlamp Alignment Actuator - Description
DESCRIPTION
The headlamp leveling motor (1) is located on the rear lower surface of each headlamp 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 (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 lower rearward surface and a plastic pushrod with a ball formation (3)
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 engine compartment wire harness.
The headlamp leveling motor is serviced as a unit with the headlamp unit. The motor cannot be repaired and, if ineffective or damaged, the entire
headlamp unit must be replaced.
