Engine Output Control
When the TCS is activated, the control unit signals the throttle actuator, located next to the throttle valve. The throttle
actuator is linked to the throttle valve through a series of reduction gears. Although the accelerator pedal position is
still within the driver's control, the throttle valve is automatically relaxed to achieve optimum traction.
