System Description: Notes

The adaptive front lighting control system consists of the adaptive front lighting control unit, suspension stroke sensor, steering angle sensor, headlight leveling motors, adaptive front lighting gearbox, AFS indicator in the gauge control module, and AFS OFF switch. The function of the system is to adjust the headlights for best aiming of the headlight beams. The suspension stroke motors move the headlight aiming up and down, and the adaptive front lighting gearbox moves the headlight aiming left and right. The suspension stroke sensor sends signals regarding vertical movement via the control unit to the headlight leveling motors, and the steering angle sensor and vehicle speed pulse send signals regarding horizontal movement via the control unit to the adaptive front lighting gearboxes. Also the control unit has a self-diagnostic function and fail-safe function.
