AHLS provides driver with the best visibility by adjusting vertical direction of the headlamp. It consists of AHLS ECU, Linkage and actuator. The height sensor measures the angular displacement of lever by measuring the magnetic field of stator parts formed by rotation of rotor.
AHLS ECU sets DTC C1367 if AHLS ECU detects no signal changes inside of axle(height) sensor while vehicle is driving over 30km/h for 5min.
