Special Tools Required

- Guide pin tool 07AAG-SVBA100

Front

1. Turn the ignition switch to LOCK (0).

2. Release the clamp (A), then disconnect the wheel speed sensor connector (B).

3. Remove the clips, the bolt, and the wheel speed sensor (C).

4. Install the wheel speed sensor in the reverse order of removal, and note these items:
- Install the sensor carefully to avoid twisting the wires.

- If the wheel speed sensor comes in contact with the wheel bearing, it is faulty. Investigate the cause before replacing the sensor.

5. Start the engine, and make sure the ABS indicator goes off.

6. Test-drive the vehicle, and make sure the ABS indicator does not come on.






Rear

1. Turn the ignition switch to LOCK (0).

2. Release the clamp (A), then disconnect the wheel speed sensor connector (B).

3. Remove the clips, the bolt, and the wheel speed sensor (C).






4. Apply multi-purpose grease to the wheel speed sensor O-ring (A) and the sensor hole in the knuckle (B).






5. Insert the guide pin tool (A) into the wheel speed sensor bolt hole until the shoulder of the tool contacts the wheel speed sensor bracket.
NOTE: To prevent O-ring damage, the wheel speed sensor must be installed with the guide pin tool.






6. Insert the wheel speed sensor (A) and the guide pin tool (B) into the bolt hole on the knuckle.
NOTE: To ensure proper alignment when pushing the wheel speed sensor into the knuckle housing, do not hold the sensor bracket during installation, hold the sensor wire.

7. Gently push and pull the wheel speed sensor in and out to make sure the O-ring is sliding properly in its housing. While you are doing this, make sure the sensor doesn't come out of the knuckle assembly. If the sliding effort is too high, remove the wheel speed sensor, inspect the O-ring for damage, and start the installation process again.

8. Remove the guide pin tool, then install the bolt, and tighten it to specified torque.

9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear wheel.
