Editing Traction control system (section)

==Components of traction control==
Generally, the main hardware for traction control and ABS are mostly the same. In many vehicles, traction control is provided as an additional option for ABS.

* Each wheel is equipped with a sensor that senses changes in its speed due to loss of traction.
* The sensed speed from the individual wheels is passed on to an [[electronic control unit]] (ECU).
* The ECU processes the information from the wheels and initiates braking to the affected wheels via a cable connected to an automatic traction control (ATC) valve.

In all vehicles, traction control is automatically started when the sensors detect loss of traction at any of the wheels.
