Diagnostic help

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.

First check that no slide-out of the data link connector pins for current supply (+30 circuit) and ground has occurred. Then use a test lamp to check whether any lead and/or fuse supplying the data link connector with current is faulty.

Following this, check whether the diagnostic tool works on another car.

If no fault can be found, decide whether to repair or replace the diagnostic tool.
