Code B168A Jeep Description

The Front and Rear Headlamp Level Sensors monitor changes in the relative distance between the vehicle body and the front or rear suspension members. In vehicles with High Intensity Discharge (HID) Headlamps but without the air suspension system, the sensor circuitry is energized by the Automatic Headlamp Leveling Module (AHLM) and both sensors provide hard wired inputs back to the AHLM. The AHLM uses these sensor inputs as logic for calculating when and how much to adjust the headlamp beams as part of the Automatic Headlamp Leveling feature. The Automatic Headlamp Leveling Module (AHLM) detects a short to voltage, short to ground, or an open on the LIN Lighting circuit.
