TCS Functions

With the wheel speed sensor signal from 4 wheels, the VDC/TCS/ABS control module detects a wheel spin on the drive wheels. If a wheel spins, the control module controls brake fluid pressure on rear LH and RH, and cuts the fuel to the engine. It also closes the throttle valve to reduce the engine torque. Furthermore, throttle position is controlled to the appropriate engine torque.
Depending on road circumstances, the driver may have a sluggish feel. This is not abnormal, because the optimum traction has the highest priority by TCS operation.
When the vehicle is passing through a road where the surface friction coefficient varies, down shifting or depressing the accelerator pedal fully may activate TCS temporarily.
During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.
