Theory Of Operation

The Front and Rear Headlamp Level Sensors monitor changes in the relative distance between the vehicle body and the front or rear suspension components. The sensor circuitry is energized by the Adaptive Front Lighting System (AFLS) Module and both sensors provide hardwired inputs back to the AFLS Module. The AFLS Module uses these sensor inputs as logic for calculating when and how much to adjust the Headlamp beams as part of the Adaptive Front Lighting System (AFLS).
