Fifth bow down

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 STC control module sends VR-bus message "Hydraulic valve 3 OFF" and thereafter "Hydraulic valve 1 ON" and when hydraulic valve 1 is activated, pressure from the pump is connected to pressure to the cylinders and the pistons are pulled in and lower the fifth bow.
