The TCS function can be turned ON/OFF by means of a spring-loaded switch on the dashboard to the right of the steering wheel. turning the TCS function off causes the TCS OFF lamp on the main instrument unit to light up.

The switch is connected to the TC/ABS control module pin 31 and to grounding point G33P (LHD) or G34S (RHD). The TCS/ABS control module supplies B+ from pin 31 and when the disengaged depending on the current state.

the switch can be used to disengage the TCS function at speeds below 60 km/h (37.5 mph) or to engage it at an optional speed. The TCS function is always engaged with the ignition is turned ON.
