Diagnostic help
WARNING: This page is about a different car, the 2003 Saab 9-3 and 2002 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The car is driven and cruise control engaged while checking the conditions for cruise control with the diagnostic tool. Start fault diagnosis on the condition that cannot be fulfilled.
The diagnostic tool contains a group of readings entitled "REASON CC WAS SWITCHED OFF". The values are from the latest occasion cruise control was working and shows the reason it was disengaged. They are stored as long as the control module is energized and are therefore suitable for locating intermittent faults.

- Cruise A, unit ON/OFF.
- Cruise B, unit ON/OFF.
- Cruise C, unit ON/OFF.
- Clutch or Brake Switch, unit ON/OFF.
- Brake light, unit ON/OFF.
- Vehicle Speed (Wire from ABS), unit km/h.
- Vehicle Speed (Bus from MIU), unit km/h.
- All values in group "CONDITIONS FOR CRUISE CONTROL".
- All values in group "REASON CC WAS SWITCHED OFF".
