TROUBLESHOOTING
BASIC TROUBLESHOOTING CONDITIONS
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
NOTE
Before starting the troubleshooting procedure, make sure that the following items have been checked
okay.
DIs the appropriate steering wheel installed at the center of the steering column shaft correctly?
DAre the tire, wheel size, specifications, air pressure, balance, and wear state normal?
DIs the wheel alignment normal?

systems?
DIAGNOSIS FUNCTION
READING DIAGNOSIS CODE
Read a diagnosis code by the MUT-IIor ACD mode indicator
lamp. (Refer to GROUP 00 - How to Use Troubleshooting/
Inspection Service Points.)
NOTE
Connect the MUT-IIto the diagnosis connector (16-pin).
ERASING DIAGNOSIS CODES
When using the MUT-II
Connect the MUT-IIto the diagnosis connector (16-pin) and
erase the diagnosis code.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.

(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.

MEASUREMENT (VEHICLES WITHOUT AYC)>
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.

5. Operate the MUT-II, drive the torque transfer differential
(item No.06 and 07) forcibly.
NOTE
(1) Drive the clutch operating mode forcibly for 1 minutes,
release the operation automatically. Drive can also
be cleared forcibly using the Clear key of MUT-II.
(2) If the hydraulic unit function has been stopped by
fail-safe, the torque transfer differential cannot be
forcibly driven.
6. Operating the MUT-II, by service data (item no.07 and 08),
check the condition of the wheel speed below.

The left rear wheel is faster 2km/h than right rear wheel.

The right rear wheel is faster 2km/h than left rear wheel.
NOTE
If the above are not satisfied, check the oil pressure as
the system may be faulty.
OIL PRESSURE CHECK
1. Lift up the vehicle.
2. Set the MUT-IIto the 16-pin diagnosis connector.
Caution
Turn the ignition switch to the LOCK (OFF) position
before connecting or disconnecting the MUT-II.
3. Turn the ignition switch to ON.
4. Disconnect the hydraulic unit and the hydraulic unit hose
assembly, connect the special tool to L port, put the lid
to R port or connect the hydraulic unit hose assembly
disconnected from L port to R port.
5. Operating the MUT-II, drive the hydraulic unit forcibly
(item No.02).
NOTE
(1) Drive the operation check mode of the clutch left
side for 1 minutes, release the operation automatically.
Drive can also be cleared forcibly using the Clear
key of MUT-II.
(2) If the function has been stopped by fail safe, the
hydraulic unit cannot be cleared forcibly.
6. Check that the generated oil pressure of the hydraulic
unit satisfies the standard value.
Standard value: 0.9 – 1.1 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. Check the oil pressure of the clutch right side following step
4 through 6. Connect the special tool to R port, put the lid

(4) For prevention of front wheel lateral runout, install
extension fittings on front towing eye and tie down hook,
and install both ends on anchor plate.
(5) For prevention of vehicle from starting out, install chain or wire (the other end of which is tightly fixed on rear
towing eye) on the vehicle.
(6) Ensure that speedometer indication range is within standard value, or pointer deflection is within limit value.
