Control Module: Ground: Diagnostics
WARNING: This page is about a different car, the 2006 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.
If ground is not present, the display will not light up when the ignition is turned on.
If sensor ground is short-circuited to 5 V or B+ then diagnostic trouble code B2945 is generated.
