Key switch, luggage compartment disarm

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 key switch is located by the luggage compartment lock and is grounded through contact with the body. The switch is powered by a pulse width modulated (approx. 3.5%) voltage via a 1 k/ohm pull-up in TWICE. When the key is turned in the lock, the switch will close and ground the control module input. The luggage compartment is then disarmed.
