GDL Bulbs (2006-2013): Design: Calibration
CAUTION:
Position sensor calibration is required after work such as sensor removal/installation, or replacement of a sensor, the control module, rear axle, front axle, bushings, shock absorber or springs.
Calibrate using VIDA (Volvo scan tool).
Calibration must always be performed with the vehicle unlocked and stationary on a level surface.
There are diagnostics for the position sensors.
Beam adjustment is carried out conventionally (via adjustment screws by the headlight).
