2. When a difference between two of the signals input from the auto leveling sensors is detected, the auto leveling control module verifies the vehicle attitude, then calculates the amount of optical axis adjustment. The auto leveling control module compares the actual and required positions of the reflector, then inputs a command signal to the headlight leveling actuator.
