Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, torque wrench, and a flat-head screwdriver.
Ensure the vehicle is parked on a level surface and that the headlights are clean.
Disconnect the vehicle battery to reset the electronic systems.

2. Resetting the Adaptive Headlights

Reconnect the Battery:
- Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
- Ensure connections are tight to prevent power loss.
Use the OBD-II Scanner:
- Connect the OBD-II scanner to the vehicle’s diagnostic port.
- Turn the ignition to the “ON” position without starting the engine.
- Access the headlight control module through the scanner and select the option to reset the adaptive headlights (specific steps may vary by scanner model).
Manual Calibration (if necessary):
- Start the engine and turn on the headlights.
- Drive the vehicle straight at a speed of 20-30 mph for a few minutes to allow the adaptive headlights to recalibrate automatically.
Check Headlight Alignment:
- Use a level wall to verify headlight beam alignment. Adjust if necessary using the adjustment screws located on the headlight assembly.
- Use the torque wrench to tighten screws to manufacturer specifications (typically around 7-10 Nm).

3. Confirming Proper Operation

Turn the steering wheel left and right at a slow speed to ensure the adaptive headlights move accordingly.
Check for any warning messages on the dashboard and ensure they are cleared.
