Traction Control System (TCS)

The TCS control unit receives signals about the vehicle's speed, direction, and traction from the wheel sensors, steering angle sensor, and lateral acceleration (LA) sensor. Based on these signals, the control unit will determine the optimum amount of wheel spin. For any given driving situation, the control unit will determine the amount of wheel spin best suited to the driver's needs and, if necessary, will then signal the TCS control valve actuator and powertrain control module (PCM) to reduce engine power.
