WHEEL SENSORS
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:
lAs much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.
lTake care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts and nuts to the specified
torques.
lWhen installing, make sure there is no foreign material such as iron chips on and in the mounting hole of
the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign
material and clean the mount.
lWhen installing wheel sensor, be sure to press rubber grommets in until they lock at locations shown
above in figure. When installed, harness must not be twisted.
