On-vehicle Service
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.
<Driving item No.06 forcibly>
The left rear wheel is faster 2km/h than right rear wheel.
<Driving item No.07 forcibly>
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-II to 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
to L port or hydraulic unit hose assembly disconnected
from R port to L port, use the MUT-II drive item No.07
(operation check mode of clutch right side) forcibly.
