Rear Axle Speed Sensor: Description and Operation
PURPOSE
A variable reluctance sensor and toothed speed indicator ring used to determine wheel speed.
OPERATION
As the ring teeth pass by the reluctance sensor, a sine wave signal is generated and sent to the Rear Antilock Brake System (RABS) control
module. The frequency of the sine wave is directly proportional to rotational wheel speed.
