REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the following when installing sensor.
As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.
Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front wheel hub and bearing assembly and rear final drive. This is to avoid damage to
sensor wiring and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the following when installing sensor. Tighten installation bolts to specified torques.
When installing, make sure there is no foreign material such as iron chips on pick-up and mount-
ing hole of sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.
When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body panel). When installed, harness
must not be twisted. White line on harness must be visible from front.

REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove LH side fender protector. Refer to EI-24, "
FENDER PROTECTOR" .
4. Remove ABS actuator and electric unit (control unit) mounting nuts.
5. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).
If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) can not be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.
Before servicing, disconnect battery cables.
To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten to
the specified torque.
Do not apply excessive impact to actuator, such as dropping it.
Do not remove and install ABS actuator and electric unit (control unit) by holding harness.
