USED
1. Check that the doors lock normally when the key
is used.
2. Insert the ignition key.
CAUTION
Before connecting or disconnecting the earth,
turn the ignition switch to the "LOCK" (OFF)
position.
3. Connect the diagnosis connector to the special

register the code.
6. Once the program is saved, it will operate once
with the all doors and tailgate lock and unlock
operations. 7. If you are using two or more transmitters or have
added a second transmitter, the same registration
procedure should be carried out within one minute
after registering the code for the first transmitter.
8. Registration mode will be cancelled under the
following conditions:
•When the secret code for four transmitters has
been registered;
•When one minute has passed after registration
mode started;
•When the diagnosis connector is disconnected
from earth;
•When the key is removed from the key cylinder;
9. After the registration is completed, remove the
ignition key and close all the doors, and then
check that the keyless entry system operates
normally.
WHEN THE MUT-II IS USED
1. Check that the doors lock normally when the key
is used.
2. Insert the ignition key.
CAUTION
Before connecting or disconnecting the MUT-II,
turn the ignition switch to the "LOCK" (OFF)
position.
3. Connect the MUT-II to the diagnosis connector.
4. Press the hazard warning switch six times within
10 seconds.

GENERAL INFORMATIONM1543009901274
IGNITION KEY REMINDER BUZZER
The ignition key reminder buzzer will sound under
the following condition, and warn the driver to
remove the ignition key.
•The driver's door is opened when the ignition
switch is at "LOCK" (OFF) or "ACC" position
without removing the ignition key.
However, the lamp reminder buzzer will take
precedence over this function.
DOOR LOCK PREVENTION FUNCTION
If the key is left in the ignition switch while the driver’s
door opened or the assistant door opened, all door
are automatically unlock to prevent locking the
ignition key in the vehicle after door is locked.
IMMOBILIZER SYSTEM
The immobilizer system consists of the ignition key
with a transponder, the immobilizer-ECU, and the
engine-ECU or engine-A/T-ECU . Only
the registered ignition key permits the engine to start,
therefore, the engine can never be started by means
of a forged key or by connecting the ignition wiring
directly. The system is significantly safe and reliable
against theft. In addition, the driver has only to turn
the ignition switch to the "ON" position to activate the
immobilizer system. If the requirements for starting the engine are not satisfied, the engine will be
immobilized. If a registered ignition key is lost, all
your ignition keys need to be registered again using
MUT-II/III to ensure security (Refer to P.54A-20). An
additional ignition key can be registered as follows
(only if no ignition keys are lost):
•Using MUT-II/III (Refer to P.54A-20).
OPERATION
1. When the ignition switch is turned to "ON"
position, the engine-ECU or
engine-A/T-ECU sends a requirement for
the encrypted code to the immobilizer-ECU (at
this time, the engine is remobilized).
2. When the immobilizer-ECU receives the
requirement from the engine-ECU or
engine-A/T-ECU , the immobilizer-ECU
supplies power to the transponder inside the
ignition key via the antenna. The energized
transponder sends the encrypted code back to the
immobilizer-ECU via the antenna.
3. The immobilizer-ECU judges the encrypted code
with its code logic in itself. If they are identical, the
immobilizer-ECU sends the encrypted code to the
engine-ECU or engine-A/T-ECU.
4. If the engine-ECU or engine-A/T-ECU can
not receive the encrypted code, the engine will be
immobilized.

ON-VEHICLE SERVICE
HOW TO REGISTER ENCRYPTED CODEM1543008100410
CAUTION
Because registering the encrypted codes is done
after all previously-registered codes have been
erased, you should keep all of the ignition keys
that have already been registered accessible.
If the ignition key, Immobilizer-ECU,
engine-ECU or engine-A/T-ECU is
replaced or an ignition key is added, encrypted
codes of all the ignition keys must be registered. (A
maximum of eight different ignition key can be
registered.) Moreover, when the immobilizer-ECU
has been replaced, you will need to use MUT-II/III to
register the immobilizer-ECU and input the vehicle
secret code and to register the password (secret
code) that the owner specifies into the
immobilizer-ECU.
If an attempt is made to start the engine with an
unregistered ignition key, cranking occurs, but fuel
supply is cut off to disable the engine. In
approximately.
NOTE: Engine-ECU or engine-A/T-ECU
has an encrypted code for immobilizer-ECU, and the
encrypted code is registered in the immobilizer-ECU
and ignition key.
POINTS TO NOTE DURING OPERATION
If none of the functions can be used, check the
diagnosis codes, and after carrying out any
necessary repairs, repeat the operation.
If an incorrect password is input ten times in a row,
the immobilizer-ECU judges that an unauthorized
operation is being attempted. Start-prevention mode
will be set, and engine operation will stop and all
special functions will be disabled. If the ignition
switch is turned to "ON" position, "Unauthorized
operation, start- prevention mode" will be cancelled.
KEY ID (ENCRYPTED CODE)
REGISTRATION
All ignition keys can be registered with MUT-II.
Additional ignition keys can be registered with
MUT-II.
Registration with the MUT-II
CAUTION
To prevent damage to MUT-II, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting MUT-II.
NOTE: .
•Using the key ID register function will cause all
key IDs that have been previously registered in
the immobilizer-ECU to be erased. All keys need
to be registered. Those which have been
registered before should be on hand before using
this function.
•If registering more than one key, do not
disconnect MUT-II halfway through the
registration process.
•After registering key IDs, check that the engine
can be started using all of the keys that have
been registered. If the engine will not start, refer
to Immobilizer System Diagnosis P.54A-6.
1. Connect MUT-II to diagnosis connector (16- pin).
2. Turn the ignition switch to "ON" position.
3. At "System Select," press "YES"

the ignition keys.
13.Check that the immobilizer system diagnosis
code and MPI system diagnosis code did not set.
14.Turn the ignition switch to "LOCK" (OFF) position.
15.Disconnect MUT-II.
Registration of additional keys with the

Additional key(s) can be registered with the MUT-II
while keeping all existing key data.
CAUTION
To prevent damage to MUT-II, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting MUT-II.
NOTE: To register additional keys with the MUT-II,
no registered keys must be lost.1. Connect MUT-II (MB991502) to the 16-pin
diagnosis connector.
2. Turn the ignition switch to "ON" position.
3. At "System Select," press "YES"
4. Select "Immobilizer," press "YES".
