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.
A reading of the ON/OFF status of the switch can be obtained with the diagnostic tool.
- Select: "Read values "
- Select "Switch, TCS OFF"
With the switch depressed the reading obtained should be ON.
If the lead is grounded for more than 10 seconds, the TC/ABS control module will engage the TCS function and after that it will not be possible to disengage the function without first switching off the ignition and then switching it on again.
