INFOID:0000000005234658

REMOVAL

Be careful with the following when removing sensor.
• Never twist sensor harness as much as possible, when removing it. Pull sensors out without pulling sensor

harness.

• Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before removing front

or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.

INSTALLATION

Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
Refer to 

BRC-131, "FRONT WHEEL SENSOR : Exploded View"

.

• 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 mate-
rial and clean the mount.

.

• 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 mate-
rial and clean the mount.

• When installing a rear LH wheel sensor, be sure to pass the wheel sensor harness under the breather hose.
