AV-SCANNER / Service function guides / Body and comfort
This guide covers the complete process of leveling adaptive headlights after replacing components such as sensors, control modules, or the headlamp assemblies themselves. It is written for working mechanics and experienced DIYers who already understand basic electrical and suspension systems. You will learn how the adaptive headlamp system determines vehicle attitude, when a calibration is mandatory, and how to perform the service function correctly across different vehicle architectures. After finishing, you will be able to prepare the vehicle, run the adaptation procedure, verify the beam pattern, and diagnose common failures without guesswork.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
