Disconnecting the glass breakage sensor: Disconnection
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.
Disconnection is accomplished (key must be removed from the ignition) by pressing in the NIGHT PANEL button for a few seconds. The tilt sensor is also disconnected. The glass breakage sensor is automatically disconnected on the convertible model if the car is armed with the soft top lowered (open).
Disconnection is confirmed with the message DOOR ALARM ONLY on SID. The car must then be locked within 3 minutes if the disconnection is to be valid when the alarm is armed.
