Benefit from the experience of one of the worlds premier automotive brake suppliers and specialists. The control systems for ABS, TCS and ESC determine the wheel speed based on signals sent by the wheel speed sensors. This information is used to prevent the wheels from locking and determine when the wheels are spinning, taking appropriate control action to maintain the vehicles stability and steering responses. In addition, it is possible to capture the rotational direction this supports functions such as hill start assist and the park assistance system. Do not question the part you are installing, choose OEM parts every time.
