Headlamp Range Adjustment (Certain Markets)
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
There are two motors, one on each headlamp, which angle the headlamps upwards or downwards to control the range of the beam. The motors are on the rear of the headlamps.
The motors are controlled by a thumb wheel which is located in the light switch module (LSM) on the dashboard by the side of the steering wheel.
If the thumb wheel is turned, information is transmitted to the motors which adjust the headlamps accordingly.
There are diagnostics for the headlamp range adjustment.
