| TCS - Traction control system |
| t
| TCS (traction control system) is fitted only on vehicles with front-wheel drive. On these vehicles it is important to check the control unit coding (vehicles not equipped with ESP → Chapter, vehicles with ESP → Chapter). The TCS limits the engine power in order to prevent the driven wheels from spinning under acceleration. The system operates by reducing engine torque and is active at all speeds. The EDL and TCS functions act together to assist acceleration. The warning lamp flashes at a rate of three times per second when the control function is actually working. |
| t
| The TCS requires an exchange of data between ABS with EDL control unit -J104- and the engine control unit. The control units communicate with each other. The data is transmitted via CAN bus → Chapter. |
| t
| Depending on the engine version, the TCS also incorporates an engine braking control (EBC). EBC prevents the driven wheels from locking up due to excessive engine braking torque, for instance when the driver changes down from 3rd to 2nd gear. The engine braking effect is reduced via the electronic idling stabilisation control. |
| t
| If required, the TCS function can be switched off and then on again by means of the push-button switch (which may be marked ASR) on the right of the switch for the hazard warning lights. The TCS switch has no influence on the EBC function. The warning lamp lights up when the TCS is switched off. The TCS is re-activated when the ignition is switched on again. |
