2. Drain oil.
3. Tighten the oil drain plug to the specified torque.
Tightening torque: 32±2 N·m
4. Fill with specified oil till the level comes to the lower portion
of oil filler plug hole.
Specified transmission oil:
Gear oil SAE 75W-90 or 75W-85W conforming to
API GL-4
Quantity: 2.8 L
5. Tighten the oil filler plug to the specified torque.
Tightening torque: 32±2 N·m

FLUID CHECK VEHICLES WITH ACD AND AYC>
1. Remove the maintenance lid located in the luggage
compartment.
2.
If the vehicle has been run, leave it for 90 min. or more
in an ordinary temperature (10_C–30_C) to allow the
accumulator internal pressure to drop.
NOTE
If the ambient temperature is 10_C or less, allow more
time to leave the vehicle to stand idle.

Set the MUT-IIto the 16-pin diagnosis connector. Turn ON
the ignition switch, perform MUT-IIactuator test (Item
No.03), forcibly drive the hydraulic unit and remove the
pressure in the accumulator.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
NOTE
(1) In the actuator test (Item No. 03: Oil Level Check
Mode), the directional valve of the hydraulic unit is
moved to the left and right for 20 times, and then
the differential is cleared automatically. Drive can also
be cleared forcibly using the Clear key of the MUT-II.
(2) If the function has been stopped by fail-safe, the
hydraulic unit cannot be cleared forcibly.
3. Check that the fluid level in the oil reservoir is in the
range between MAX and MIN.
4. If the fluid level is lower than MIN, add the specified
fluid.
Specified fluid: Dia Queen ATF SP III
5. Reinstall the maintenance lid.

BLEEDING VEHICLES WITH ACD AND AYC>
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 the “ON” position.
4. Set the steering wheel in the straight-ahead position.
5. Perform the MUT-IIactuator test (Item No.02), and forcibly
drive the hydraulic unit.
NOTE
(1) The actuator test (Item No.01: Bleeding Mode) will
be performed for 5 minutes, after which it will be
cleared automatically. Drive can also be cleared during
forced driving using the clear key of the MUT-II.
(2) If the hydraulic unit function has been stopped by
fail-safe, the hydraulic unit cannot be forcibly driven.
6. Remove the cap of the bleeder screw on the transfer,
and connect the vinyl hose.
7
.Slowly turn the steering wheel to the left or right from
the neutral state. Loosen the bleeder screw, and check
that air is discharged together with the fluid.
8
.After the air is discharged, tighten the bleeder screw,
and return the steering wheel to the neutral state.
Caution
During bleeding, replenish the fluid so that some
always remains in the oil reservoir.
9. Repeat steps 6 and 7 several 2 to 3 times, and after
checking that no more air mixes in, tighten the bleeder
screw at the specified torque.
Tightening torque: 5±1 N·m
10. After bleeding, check the fluid level. (Refer to P. 22A-41.)
Caution
If bleeding is not performed completely, noise may
be produced from the hydraulic unit, or the durability
of the pump, etc. may drop.
11. On vehicles with AYC, perform bleeding when the
hydraulic unit is removed. (Refer to GROUP 27B -
On-vehicle Service.)
ACD OPERATION CHECK ACD OR VEHICLES WITH ACD AND AYC>
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. Start the engine.

(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.
Specified fluid: DIA QUEEN ATF SP III

WHEEL SPEED SENSOR OUTPUT VOLTAGE
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.
Terminal No.
