Conditions for soft top operation

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 following conditions must be met before the control module is able to operated the soft top.

Ignition in ON position
When the ignition is in position ON, the soft top can be operated with the ROOF button. If the ignition is turned to the ST position while the soft top is being operated with the ROOF button, the motion will stop and must be restarted by pressing the ROOF button again.
Vehicle speed below 10 km/h
The control module receives a message about the speed of the car via the I -bus from the main instrument unit. It is possible to operate the soft top when the vehicle speed is below 10 km/h, which is about the speed the car will travel in first gear at idling speed.
Soft top storage lowered (applies only when lowering (opening) the soft top)
The control module receives information on the position of the soft top storage from two microswitches. If the soft top storage is up and an attempt is made to lower (open) the soft top, operation is halted and the message CHECK SOFT TOP STORAGE is displayed on SID.
Boot lid closed
The control module receives information if the boot lid is closed via the I -bus from the TWICE control module. If the boot lid is open and an attempt is made to operate the soft top, the soft top sequence is halted and the message CLOSE TRUNK LID is displayed on SID. The boot lid must be closed, otherwise it will collide with the soft top cover when it is raised (opened).
First bow latches released from windscreen frame

Power supply to control module is between 10 -16V
The power supply to the control module must be between 10 -16V for the control module to be able to operated the soft top or the windows.
I-bus communicating correctly
