Indicator Lamp TCS OFF: Notes
WARNING: This page is about a different car, the 2001 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.
If a fault occurs in the TC/ABS system, the TCS OFF indicator lamp will be turned on via the P-bus. The warning lamp is also turned on when the system is disabled manually, which can be done at speeds below 60 km/h (37.5 mph) by pressing the TCS switch. The system can be engaged by pressing the TCS switch at any speed, whereby the TCS OFF lamp will go out again.
The lamp lights up when the ignition is switched on. If no fault is detected it goes out after 3-5 seconds.
