Door switches

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 door switches are mounted in the frame of the door concerned and grounded through the switch mounting screw to the bodywork. The switches are supplied with a pulse width-modulated (approx. 3.5%) voltage via a 1 k/ohm pull-up in TWICE. When a door is opened, the switch is closed and the control module input is grounded.

TWICE sends out information on the door position to the bus, where it is used by DICE for example for interior lighting. The anti-theft alarm also uses the door switch.
