- Wheel spin status of drive wheel is detected by wheel sensor of four wheels. Engine output and transmission shift status are controlled so that slip rate of drive wheels is in appropriate level. When wheel spin occurs on drive wheel, ABS actuator and electric unit (control unit) performs brake force control of LH and RH drive wheels (applies brake force by increasing brake fluid pressure of drive wheel) and decreases engine torque by engine torque control. Wheel spin amount decreases. Engine torque is controlled to appropriate level.

- TCS function can be switched to non-operational status (OFF) by operating VDC OFF switch. In this case, VDC OFF indicator lamp turns ON.
- VDC warning lamp blinks while TCS function is in operation and indicates to the driver that the function is in operation.
- CONSULT can be used to diagnose the system diagnosis.
- Fail-safe function is adopted. When a malfunction occurs in TCS function, the control is suspended for VDC function, TCS function and brake assist function. The vehicle status becomes the same as models without VDC function, TCS function and brake assist function. However, ABS function and EBD function are operated normally. Refer to FAIL-SAFE .
