This system uses two-wire wheel speed sensors known as active wheel speed sensors. One wheel speed sensor (WSS) and one tone wheel are located at each front and rear wheel. The rear wheel speed sensor on rear disc brake applications is mounted to the rear disc brake adapter (Fig 1 ). The rear tone wheel is an integral part of the rear wheel hub and bearing.
