FRONT WHEEL SENSOR: Removal and Installation

CAUTIONBe careful not to damage front wheel sensor edge and sensor rotor teeth. When removing the front wheel hub, first remove the front wheel sensor from the steering knuckle. Failure to do so may result in damage to the front wheel sensor, making the front wheel sensor inoperative. Pull out the front wheel sensor, being careful to turn it as little as possible. Do not pull on the front wheel sensor harness. Before installation, check if foreign objects, such as iron fragments, the pick-up part of the front wheel sensor or to the inside of the hole in the steering knuckle for the front wheel sensor, or if a foreign object is caught in the surface of the sensor rotor. Fix as necessary and then install the front wheel sensor.

REMOVAL

  1. Remove wheel and tire using power tool. Refer to " «REMOVAL AND INSTALLATION»(ref-675581-S28220831532014120500000) ".
  2. Remove fender protector. Refer to " «REMOVAL AND INSTALLATION»(ref-675580-S35121108852014120500000) ".
  3. Disconnect the harness connector from the front wheel sensor.
  4. Remove bolt and front wheel sensor from steering knuckle.
  5. Release front wheel sensor harness clips from the vehicle.

INSTALLATION

Installation is in the reverse order of the removal.

CAUTIONDo not twist front wheel sensor harness when installing front wheel sensor. Check that grommet (2) is fully inserted to bracket (1). Check that front wheel sensor harness is not twisted after installation.

REAR WHEEL SENSOR: Removal and Installation

CAUTIONBe careful not to damage rear wheel sensor edge and sensor rotor teeth. When removing the rear wheel hub, first remove the rear wheel sensor from the back plate. Failure to do so may result in damage to the rear wheel sensor, making the rear wheel sensor inoperative. Pull out the rear wheel sensor, being careful to turn it as little as possible. Do not pull on the rear wheel sensor harness. Before installation, check if foreign objects, such as iron fragments, the pick-up part of the rear wheel sensor or to the inside of the hole in the back plate for the rear wheel sensor, or if a foreign object is caught in the surface of the sensor rotor. Fix as necessary and then install the rear wheel sensor.
