REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:
As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.
Take 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.
When 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.
When installing front wheel sensor, press rubber grommets of strut bracket and body all the way in until
they get locked, and be careful not to apply a twist to harness. Harness should not be twisted after instal-
lation. (Install it with harness paint mark on body side grommet facing front of vehicle, and the strut side
grommet facing outside of vehicle.)
