• The auto leveling control module is located in the underside of the blower unit in the dashboard.
• The auto leveling control module verifies changes in vehicle speed and attitude based on signal inputted from
the ABS (DSC) HU/CM, and front and rear auto leveling sensors. The control module then calculates the
optimal direction for the optical axis.
• Based on the calculation of the optical axis adjustment amount, the auto leveling control module controls the
headlight leveling actuator.
