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 ABS actuator and electric unit (control unit) mounting nuts.
4. 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) cannot 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
with 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.
INSTALLATION
Install is in the reverse order of the removal.
CAUTION:
Be careful of the following when installing ABS actuator and electric unit (control unit).

Tighten the mounting bolts and nuts with the specified torque.

After the work, bleed air from brake piping. Refer to BR-10, "Bleeding Brake System" .

After installing body harness connector in the actuator, make sure connector is securely locked

When replacing ABS actuator and electric unit (control unit), calibrate Steering angle sensor neu-
tral position. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.

closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter (SST),
apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
