Main Lighting

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The main and dipped beams, rear lights, numberplate lighting, and parking lights are included in the main lighting. The light switch must be in position 2 and the ignition ON to operate the main lighting. The main and dipped beams are controlled by DICE via 2 relays. The parking lights are monitored by TWICE (like a filament monitor).

The functions of the light switch in the car are controlled by the control module DICE. There are 3 different program alternatives for DICE that can be selected to suit the car market destination.

On certain markets, the dipped beam is used as daylight driving lights. The light switch must then be in position 0.

The parking lights are on when the light switch is in position 1, if the ignition is OFF. Depending on the current program alternative, the parking lights can be on when the light switch is in another position. In certain markets, the dipped beam is used as daylight driving lights.

The main and dipped beam function is monitored by a filament monitor. In the event of a fault, SID (Saab Information Display) will produce an acoustic alarm signal and display FRONT LIGHT FAILURE.

The rear lights (LH and RH) are monitored by TWICE. In the event of a fault in the rear light function, SID will produce an acoustic alarm signal and display REAR LIGHT FAILURE.
