Factory service manual
From the 2008 KK factory manual — descriptions, specs, torque & procedures for this part.
REAR WHEEL SPEED SENSOR
A wheel speed sensor is used at each wheel. The front sensors are mounted to the steering knuckles. Front tone wheels are internal to the front bearing. The rear sensors are mounted at the outboard end of the axle. Tone wheels are mounted to the outboard ends of the front and rear axle shafts. The gear type tone wheel serves as the trigger mechanism for each sensor.
REAR WHEEL SPEED SENSOR
The sensors convert wheel speed into a small digital signal. The ABM sends 12 volts to the sensors. The sensor has an internal magneto resistance bridge that alters the voltage and amperage of the signal circuit. This voltage and amperage is changed by magnetic induction when the toothed tone wheel passes the wheel speed sensor. This digital signal is sent to the ABM. The ABM measures the voltage and amperage of the digital signal for each wheel.
