BLEEDING
1. Lift up the vehicle.
2. Connect the MUT-II to the 16-pin diagnosis connector.
Caution
Before connecting or disconnecting the MUT-II,
always turn off the ignition switch.
3. Turn on the ignition switch.
4. Operate the MUT-II (Item No.10) to activate the hydraulic
unit forcibly.
NOTE
(1) The forced activation (air bleeding mode) will be
automatically canceled after 5 minutes operation. It
can also be canceled forcibly by operating the clear
key on the MUT-II.
(2) While this function is being disabled by the fail-safe
function, the forced activation of the hydraulic unit
can not be executed.
5. Remove the cap of the left bleeder screw on the torque
transfer differential and connect a vinyl hose.
6. Gradually turn the steering wheel clockwise from the
straight-ahead position. At this time, loosen the left bleeder
screw and check that fluid is discharged with air.
7. After air has been completely discharged, tighten the
bleeder screw.
Caution
While the system is being bled of air, add fluid as
necessary to ensure that it is left in the oil reservoir
during the entire procedure.
8. Repeat steps (6) and (7) two to three times until no air
bubbles are recognized in the fluid that comes out. Then,
tighten the bleeder screw to the specified torque.
Tightening torque: 9 Nm
9. Perform steps (5) through (8) for the right bleeder screw.
Note, however, that the steering wheel should be turned
counterclockwise.
10. After the system has been completely bled of air, check
for the fluid level. (Refer to P.27-33.)
Caution
If the system is not completely bled of air, the hydraulic
unit could generate noise, degrading pump durability.
AYC OPERATION CHECK
1. Lift up the vehicle.
2. Connect the MUT-II to the 16-pin diagnosis connector.
Caution
Before connecting or disconnecting the MUT-II, always
turn off the ignition switch.
3. Start the engine.
4. Operate the MUT-II with the transmission in 2nd or a
higher gear and check to ensure that the vehicle speed
is higher than 10 km/h using the Data List (Item 10).

NOTE
(1) Hold the steering wheel in the neutral position.
(2) If the steering wheel is turned, it may happen that
the AYC system continues to operate (operation
sounds are heard from the torque transfer differential).
However, it does not mean a system failure. If such
a case is encountered, perform the following
operations with the steering wheel in the neutral
position to cancel the AYC function.

Disengage the clutch.

Set the transmission to neutral.

Stop the engine.
5. Operate the MUT-II (Item Nos.13 and 14) to activate
the torque transfer differential.
NOTE
(1) The forced activation (clutch operation mode) will be
automatically canceled after 1 minute operation.
It can also be canceled forcibly by operating the clear
key on the MUT-II.
(2) While this function is being disabled by the fail-safe
function, the forced activation of the torque transfer
differential can not be executed.
6. Operate the MUT-II to confirm that the several speeds
of the wheels are as shown below, using the Data List
(Item Nos.07 and 08).
<Forced activation Item No.13 is being executed>
The speed of left rear wheel is more than 2 km/h
higher than that of right rear wheel.
<Forced activation Item No.14 is being executed>
The speed of right rear wheel is more than 2 km/h
higher than that of left rear wheel.
NOTE
If the above requirements are not satisfied, the system
is probably failed. Check the hydraulic pressure.
HYDRAULIC PRESSURE CHECK
1. Lift up the vehicle.
2. Connect the MUT-II to the 16-pin diagnosis connector.
Caution
Before connecting or disconnecting the MUT-II,
always turn off the ignition switch.
3. Turn on the ignition switch.
4. Disconnect the joint between the hydraulic unit and the
hydraulic unit hose assembly. Connect the special tool
to the L port. To the R port, attach a blind plug or connect
the L port of the removed hydraulic unit hose assembly.
5. Operate the MUT-II (Item No.13) to activate the hydraulic
unit.
NOTE
(1) The forced activation (clutch left side operation check
mode) will be automatically canceled after 1 minute
operation.
It can also be canceled forcibly by operating the clear
key on the MUT-II.

SECRET CODE REGISTRATION METHOD
Each individual secret code is registered inside
the transmitter, and so it is necessary to register
these codes with the EEPROM inside the receiver
in the following cases.

When either the transmitter or receiver is
replaced;

If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of two different codes can be stored
in the memory area of the EEPROM (two different
transmitters can be used). When the code for the
first transmitter is registered, the previously-regis-
tered codes for two transmitters are cleared.
Therefore, if you are using two transmitters or are
adding a second transmitter, the codes for both
transmitters must be registered at the same time.
Before beginning with the registration, check that
the doors lock normally when the key is used.
1. Connect the MUT-II to the diagnosis connector.
NOTE
This will connect terminal (1) of the diagnosis
connector to earth, and the system will be in
secret code registration standby mode.
Caution
Always turn the ignition switch to OFF before
connecting and disconnecting the MUT-II.
2. Close all the doors.
3. Turn the ignition switch to ACC and then back
to OFF.NOTE
The doors will lock and unlock once at this
time and the system will switch to registration
mode.
4. Press the transmitter switch, and then press
it two times within 10 seconds of the first press.
This will register the code.
5. After registration is completed, the doors will
be automatically locked and unlocked once.
6. If you are using two transmitters or have added
a second transmitter, the same registration
procedure should be carried out for the second
transmitter, and it should be carried out within
one minute after registration of the code for
the first transmitter has been completed. After
the second registration is completed, the doors
will be automatically locked and unlocked once.
7. Registration mode will be cancelled if one of
the following conditions is met.

When the secret codes for two transmitters
have been registered;

When 1 minute has passed after
registration mode started;

If the MUT-II is disconnected (the earth
connection is broken);

If the ignition switch is turned to ON;

If any of the doors are opened;
8. After registration is completed, carry out the
following to check if the keyless entry system
is operable properly.

Remove the ignition key.

Close all the doors.

BODY – Sunroof42-11
Inspection Procedure 2
The motor does not reverse its direction when a load of
140 N or more is applied while the sunroof is closing.
Probable cause
The sunroof-ECU monitors the load conditions from the amount of current flowing
to the motor. If more than the constant amount of current is flowing, the direction
of motor operation is reversed to prevent jamming.
If the motor does not reverse direction even when an excessive load is being applied,
the cause may be a malfunction of the sunroof-ECU.
Malfunction of sunroof-ECU
Replace the sunroof-ECU.
Inspection Procedure 3
The timer does not operate for 30 seconds after the
ignition switch is turned to OFF.
Probable cause
The sunroof-ECU has a timer function which operates for 30 seconds after the ignition
switch is turned to OFF. If the timer does not operate, the cause may be a malfunction
of the sunroof-ECU or of the wiring harness or connector.
Malfunction of sunroof-ECU

Malfunction of wiring harness or connector

Inspection Procedure 4
Opening or closing of the sunroof is possible for 30
seconds after turning the ignition switch to OFF, but the
timer function is not extended when the driver’s side door
is opened within this period.
Probable cause
The sunroof timer operation period is extended when an on signal is output from
the driver’s-side door switch. Because of this, if the timer operation period is not
extended, the cause may be a malfunction of the door switch input circuit.
