Indicator Lamp, TCS

Indicator Lamp, TCS












The TCS indicator lamp is located on the left-hand side of the main instrument unit (in the tachometer). The lamp comes on when the TCS modulation is active.

The indicator lamp is turned on when the TC/ABS control module sends information on the P-bus.

The lamp comes on after a brief delay (300 ms) when TCS modulation is active and stays on as long as the system is operational but at least for one second. The lamp is turned on for 3-5 seconds when the ignition is switched on.

Diagnostics
The function has no diagnostics.

Indicator lamp, TCS OFF












If a fault occurs in the TC/ABS system, the TCS OFF lamp will turned on via the P-bus. The warning lamp also comes on if the system is disengaged manually, which can be done at speeds below 60 km/h (37.5 mph) by pressing in the TCS button. The system can be engaged at any speed by pressing the TCS button, whereby the TCS OFF lamp will be turned off again.

The lamp will come on for 3-5 seconds when the ignition is switched on and then go out if no faults are detected.

Diagnostics
A system error affecting the ABS function will turn on the warning lamps for ABS and brakes and the central warning lamp.

If the bus message from TC/ABS is absent for 2 seconds, the TCS OFF and ABS lamps will be turned on. If the bus message remains absent for another 8 seconds, the central warning lamp and the brake warning lamp will be turned on as well.
