Note:

If TC operation is triggered (vehicle travelling and wheels spin), the drive wheels are decelerated. This can be clearly observed when the vehicle is jacked up and the wheels turn.

In the Motronic control unit, a fault occurs under this parameter: when the engine is running, the control unit recognizes that TC operation is always active. TECH 1 therefore always displays ACTIVE.

Vehicles without TC (Traction Control):

INACTIVE 0V
