Adjusting the display lighting

/ 9-3 (9400) / 2002 / 3. Electrical System / Main instrument unit / Adjustment/replacement / Adjusting the display lighting

The display lighting is controlled principally by the cabin light sensor and the rheostat incorporated in the SID. To these values coming from the SID on the bus, the main instrument unit adds an offset value which can be adjusted with Tech 2. As it is only an offset value, it is not possible to turn the display lighting completely on or off. The adjustment is in %.
