NOTICE
Make sure there are no foreign materials in
the front wheel sensor rotor and front wheel
sensor. Foreign materials cause damage to
the front wheel sensor rotor and front wheel
sensor.
TIP
When installing the front wheel sensor, check
the wheel sensor lead for twists.
7. Measure:
• Distance "a"
(between the wheel sensor rotor "1" and
wheel sensor "2")
Out of specification → Check the wheel bear-
ing for looseness, and the front 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 wheel
sensor rotor and front wheel sen-
sor)
0.6–1.8 mm (0.02–0.07 in)
