Rear Wheel Speed Sensor (ABS)

A four wheel antilock braking system is optional equipment on this vehicle. The rear wheel speed sensor is mounted on the rear differential carrier. The rear wheel speed sensor consists of a magnetic core, with a magnet and coil. The speed sensor exciter ring is mounted on the differential case behind the ring gear and rotates with it. An electrical impulse is produced each time a gear tooth of the speed sensor exciter ring passes the rear wheel speed sensor allowing it to receive a signal in direct proportion to rear axle speed. This signal is then sent to the Electronic Brake Control Module (EBCM).
