NOTE
If the engine-ECU is replaced, the immobilizer-ECU and
ignition key should be replaced together with it.
DIAGNOSIS FUNCTION
ENGINE WARNING LAMP (CHECK ENGINE LAMP)
If an abnormality occurs in any of the following items related
to the MPI system, the engine warning lamp will illuminate
or flash. If the lamp remains illuminated or if the lamp
illuminates while the engine is running, check the diagnosis
code output.
However, the warning lamp will illuminate as bulb check for
5 seconds whenever the ignition switch is turned to the ON
position.

6. If not within the standard value range, turn the speed
adjusting screw to make the necessary adjustment.
7. Press the MUT-IIclear key, and release the idle speed
control servo from the Actuator test mode.
NOTE
Unless the idle speed control servo is released, the
Actuator test mode will continue 27 minutes.
8. Turn the ignition switch to “LOCK” (OFF) position.
9. Disconnect the MUT-II.
10. Start the engine again and let it run at idle speed for
approximately 10 minutes; check that the idling condition
is normal.
FUEL PRESSURE TEST
1. Release residual pressure from the fuel pipe line to prevent
fuel gush out. (Refer to P.13A-125.)
2. Disconnect the high-pressure fuel hose at the delivery
pipe side.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
3. Remove the union joint and bolt from the special tool
(adapter hose) and instead attach the special tool (hose
adapter) to the adapter hose.
4. Install the special tool (for measuring the fuel pressure)
that was set up in step 3.

(1) Install the special tool (for measuring the fuel pressure)
between the high-pressure fuel hose and the delivery
pipe.
(2) Install the fuel pressure gauge set (special tool) on
the special tool (for measuring the fuel pressure)
putting the gasket between them.
(3) Connect the lead wire of the fuel pressure gauge
set (special tool) to the power supply (cigarette lighter
socket) and to the MUT-II.

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.

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

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.)

4. Set the gear to the 2nd gear or above, operate the MUT-II,
and check from the service data (Item No.09) that the
wheel speed is within 10 km/h to 20 km/h.
NOTE
(1) Set the steering wheel to the neutral position
(2) The ACD may continue operating (operation sounds
can be heard) when the steering wheel is steered,
this is not a system fault. In this case, set the steering
wheel to the neutral position, and perform the following
operations to stop the ACD.
DRelease the clutch.
DSet the gear to “N”.
DStop the engine
5. Perform the MUT-IIactuator test (Item No.05), and forcibly
drive the transfer.
NOTE
(1) The actuator test (Item No. 05: ACD Operation Check
Mode) is performed for 1 minute, 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 transfer cannot be forcibly driven.
6. Check that the front and rear wheel speeds satisfy the
following in the MUT-IIactuator test (Item No.05).

The front wheel will be faster than the back wheels by
more than 2 km/h.
NOTE
If the above are not satisfied, check the oil pressure as
the system may be faulty.
HYDRAULIC PRESSURE CHECK WITH ACD OR VEHICLES WITH ACD AND AYC>
1. Lift up the vehicle.
2. Set the MUT-IIto the 16-pin diagnosis connector.
Caution
