Make sure there are no foreign materials in

the rear wheel sensor rotor and rear wheel

sensor. Foreign materials cause damage to

the rear wheel sensor rotor and rear wheel

When installing the rear wheel sensor, check the

rear wheel sensor lead for twists.

• Distance "a"

(between the wheel sensor rotor "1" and rear

wheel sensor "2")

Out of specification

ing for looseness, and the rear wheel sensor

and sensor rotor installation conditions

(warpage caused by overtorque, wrong in-

stallation direction, rotor decentering, LOC-

TITE® on the mounting surface of the rotor,

deformation caused by an impact during ser-

vice and caught foreign materials). If there is

any defective part, repair or replace the de-

fective part.

Distance "a" (between the rear

wheel sensor rotor and rear wheel

1.3–2.1 mm (0.051–0.083 in)
