(2) If the hydraulic unit function has been stopped by
fail-safe, the hydraulic unit cannot be forcibly driven.
6. Check that the generated oil pressure of the hydraulic
unit satisfies the standard value.
Standard value: 1.0 – 1.6 MPa
Caution
While the oil pressure is checked, add fluid as
necessary to ensure that it is left in the oil reservoir
during the entire procedure.
7. If the measured value exceeds the standard value, replace
the hydraulic unit.
8. Connect the hydraulic unit and transfer connector
assembly, and tighten the flare nut at the specified torque.
Tightening torque: 34±5 N·m (when screw is dry)
26±4 N·m (when screw is applied with oil)
9. Supply the specified fluid up to the MAX level of the
oil reservoir, and bleed the oil pressure pipes.

1. Lift the vehicle, and release the parking brake.
2. Disconnect the 4WD-ECU connector, and measure at
the connector of the harness.
Caution
Insert the probe from the harness of the connector.
Inserting in the terminal side may cause contact fault.
3. Rotate the measured wheel by about 1/2 to 1
rotations/second, and check the output voltage between
the following terminals using a circuit tester (AC mV range)
or oscilloscope.

Output voltage:
Above 70 mV when measured with the circuit
tester
Above 200 mVP-P when measured with the
oscilloscope
4. If the output voltage is lower than the above values, the
following reasons may be suspected. Check or replace
the wheel speed sensor.
DExcessive clearance between the ball piece of the
wheel speed sensor and ABS rotor
DWheel speed sensor faul
INSPECTION PROCEDURE USING OSCILLOSCOPE
After checking the connected state of the harness of the
wheel speed sensor and connector, and measure the output
voltage waveform of each wheel speed sensor on the
oscilloscope as follows.
Start the engine, shift the transmission to the 1st gear to
rotate the driving wheel, and rotate the non-driving wheel
at constant velocity with the hand.
NOTE
1. It is also possible to actually drive the vehicle and observe
the waveform.
2. The output voltage is low if the wheel speed is low and
gradually increases as the speed increases.

PhenomenonProbable causeSolution
Waveform amplitude is too small or
not output at allWheel seed sensor faultReplace the sensor
Excessive waveform amplitude
(However allowed if above the
iilit df100V)
Excessive vibration or concentricity of
the axle hubReplace the hub

Wheel speed sensor installation faultCorrect the installation of the sensor
Chipping or flattening of the ABS rotorReplace the ABS rotor
Caution
As the wheel speed sensor cable follows the movement of the front or rear suspension, it will
change considerably on poor condition roads. Therefore, also observe the output voltage waveform
of the wheel speed sensor with the sensor harness vibrated to simulate special conditions such
as driving in poor road conditions.
