Motor, Headlamp Leveling: Description

An intelligent stepper motor is located within each front lamp unit on vehicles equipped with Adaptive Front Lighting System (AFLS). The stepper motor adjusts the headlight beams up, down, left or right depending on the driving conditions.

The motors are enclosed within the front lamp unit housing for protection and is connected to the vehicle electrical system through the front lamp unit wire harness. 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. Right side lamp motors are slaved to the left side control unit. The control unit is operating by the Adaptive Front Lighting Module (AFLM). For more information on the AFLS. Refer to OPERATION .

The headlight 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.
