Headlight Automatic Vertical Aim Control, On Board Diagnostic (OBD)

General information

The headlight automatic vertical aim control system keeps the low beams at a constant level even when the vehicles inclination has changed due to changes in load.

There are two level sensors, one on the front axle and one on the rear, which detect the vehicle's level of inclination. In addition, the vehicle speed signal is also used.

The control module evaluates these signals and activates the automatic headlight beam adjusting motors, when the headlights are switched on.

Headlight automatic vertical aim control is required on vehicles equipped with high intensity gas discharge (Xenon) headlights.
