HEADLIGHT LEVELING ACTUATOR

Purpose, Function

• 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, to change the headlight LO optical axis.

Construction

• The headlight leveling actuator is integrated with the front combination lights.

• The headlight leveling actuator consists of a motor which expands/contracts the shaft, a shaft, and a microcomputer which calculates the shaft expansion/contraction amount.

Operation

• The headlight leveling actuator calculates the motor drive amount based on the target optical axis signal (1) from the auto leveling control module/AFS control module and drives (2) the motor until the optical axis reaches the target optical axis.

• When the motor is driven, the shaft moves (3) back and forth and the reflector moves to change (4) 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

• Not applicable
