TCS Indicator Lamp: 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.
The TCS lamp is situated on the left-hand side of the main instrument unit (in the tachometer). It comes on when the TCS function is active.
The lamp is turned on when the TC/ABS control module sends information to the P-bus.
The lamp comes on after a slight delay (300 ms) when TCS mode is enabled and then stays on as long as the system remains operative or for at least one second. When the ignition is switched on the lamp lights up for 3-5 seconds.
