HEADLIGHT LEVELING ACTUATOR
id091800011200
Purpose, Function
• The headlight leveling actuator drives the motor and changes the headlight optical axis using current which flows according to the position to which the headlight leveling switch is switched. (With headlight manual leveling system)
• The headlight leveling actuator drives the motor based on the target optical axis voltage, which is input from the auto leveling control module/AFS control module/adaptive LED headlights control module, to change the optical axis of the headlights. (With headlight auto leveling system/adaptive front lighting system (AFS)/adaptive led headlights system)
Construction
• Built into the front combination lights.
• Consists of a motor which expands/retracts the shaft, a shaft, and a microcomputer which calculates the shaft expansion/contraction amount.
Operation
With headlight manual leveling system
1. The headlight leveling actuator calculates the motor drive amount based on the current which flows according to the position to which the headlight leveling switch is switched, and it drives the motor until the headlight reaches the target optical axis.
2. When the motor is driven, the shaft moves back and forth and the reflector moves to change the optical axis.
-
Note
-
• The headlight HI optical axis changes according to the headlight LO optical axis because the reflector of the headlights LO and HI is integrated.
With headlight auto leveling system
1. The headlight leveling actuator calculates the motor drive amount based on the target optical axis signal from the auto leveling control module/AFS control module/adaptive LED headlights control module and drives the motor until the headlight reaches the target optical axis.
2. When the motor is driven, the shaft moves back and forth and the reflector moves to change the optical axis.

Note
-
• The headlight HI optical axis changes according to the headlight LO optical axis because the reflector of the headlights LO and HI is integrated.
Fail-safe
• Function not equipped.
