TCS FUNCTION : System Description

The wheel spin of the drive wheels is detected by the ABS actuator and electric unit (control unit) using the wheel speed signals from the four wheels, so if wheel spin occurs, the drive wheel right and left brake fluid pressure control and engine fuel cut are conducted while the throttle valve opening is restricted to reduce the engine torque and decrease the amount of wheel spin. In addition, the throttle opening is controlled to achieve the optimum engine torque.
During TCS operation, TCS informs driver of system operation by blinking the SLIP indicator lamp.
Electrical system diagnosis by CONSULT is available.
