CAUTION:

• Be careful not to damage wheel sensor edge and sensor rotor teeth.

• When removing the front or rear wheel hub, first remove the wheel sensor from the wheel hub. Fail-

ure to do so may result in damage to the wheel sensor wires, making the sensor inoperative.

• Pull out the wheel sensor, being careful to turn it as little as possible. Do not pull on the wheel sen-

sor harness.

• Before installation, check if foreign objects, such as iron fragments, are adhered to the pick-up part

of the sensor or to the inside of the hole in the wheel hub for the wheel sensor, or if a foreign object

is caught in the surface of the mating surface for the sensor rotor. Fix as necessary and then install

the wheel sensor.

REMOVAL

1. Remove rear wheel sensor from back plate.
