REMOVAL

1. Remove the disc rotor. Refer to 

BR-40, "Removal and Installation of Brake Caliper and Disc Rotor"

 (front)

or 

BR-45, "Removal and Installation of Brake Caliper and Disc Rotor"

 (rear).

2. Remove the wheel sensor bolt.

• When removing the front wheel sensor, first remove the disc rotor to gain access to the front wheel sen-

sor bolt. Refer to 

BR-45, "Removal and Installation of Brake Caliper and Disc Rotor"

.

• When removing the rear wheel sensor, first remove the spare tire.

3. Pull the wheel sensor out, being careful to turn it as little as possible.

CAUTION:

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

• Do not pull on the wheel sensor harness.

4. Disconnect then wheel sensor harness connector, then remove the wheel sensor harness from the

mounts and remove the wheel sensor.

• When removing the rear wheel sensor, both sensors must be removed as they are on the same har-

ness.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Inspect wheel sensor O-ring, replace wheel sensor if damaged.

• Before installing the wheel sensor, make sure no foreign materials (such as iron fragments) are

adhered to the pick-up part of the wheel sensor, to the inside of the wheel sensor hole or on the sen-

sor rotor in the wheel hub assembly.

• Clean wheel sensor hole and mating surface with brake cleaner and a lint-free shop rag. Be careful

that dirt and debris do not enter the axle or wheel hub assembly.

NOTE:

Apply a coat of suitable grease to the wheel sensor O-ring and mating hole.
