CAUTION
•Before removing the clock spring, refer to GROUP 52B, Service Precautions (P.52B-5) and Air Bag
Module and Clock Spring (P.52B-210). Also, put the front wheels in straight-ahead position.
Failure to do so may damage the SRS clock spring and render the SRS air bag inoperative, which
results serious driver injury.

WHEN THE SPECIAL TOOL DIAGNOSIS
CODE CHECK HARNESS (MB991529) 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 earth,
turn the ignition switch to the "LOCK" (OFF)
position.
3. Connect the diagnosis connector to the special
tool diagnosis code check harness (MB991529).
NOTE: This will connect terminal (1) of the
diagnosis connector to earth, and the system will
be in secret code registration standby mode.
4. Press the hazard warning lamp switch six times
within 10 seconds.
NOTE: Once the process is completed six times,
then it will operate with all doors and tailgate lock
and unlock operations once and then go to the
save mode.
NOTE: The hazard warning lamp switch is turned
on and off alternately whenever it is pushed.
5. Press the transmitter switch, and then press it two
times within 10 seconds of the first press. This will
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.

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
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
engine-A/T-ECU
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
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
4. If the engine-ECU
not receive the encrypted code, the engine will be
immobilized.
