The automatic vertical headlight aim control system is installed on vehicles with High Intensity Gas Discharge (HID) headlights.

The system contains the following components

1. Level control system sensors at front and rear axles
2. Headlight range control module
3. Headlight beam adjusting motors integrated with headlight units

When driving, the system automatically adapts the headlight beam inclination dependent on vehicle suspension movement and load. Headlight glare to oncoming traffic is minimized.

The headlight range control module is controlled by a microprocessor and has On Board Diagnostic (OBD) capability. If malfunctions occur in any of the system components, corresponding DTCs are stored in the Diagnostic Trouble Code (DTC) memory.

Before performing any troubleshooting or inspection, always begin by checking for DTCs using the On Board Diagnostic (OBD) program. DTCs stored in memory are retrieved/checked with VAS 5051/5052 tester in mode "Guided Fault Finding".
