HOW TO REGISTER SECRET CODEM1428001000292
Each individual secret code is registered inside the
transmitter, and so it is necessary to resister these
codes with the EEPROM inside the receiver in the
following cases.
•When the transmitter or ETACS-ECU is replaced
•If more transmitters are to be used
•If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of four different codes can be stored in
the EEPROM memory (four different transmitters can
be used). When the code for the first transmitter is
registered, the previously registered codes for all
transmitters are cleared. Therefore, if you are using
four transmitters or are adding more transmitters, the
codes for all transmitters must be registered at the
same time.

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

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.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to
personal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and
paassenger (from rendering the SRS inoperative).
•Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
•MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, air bag module,
clock spring, and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection
with SRS service or maintenance) are indicated in the table of contents by an asterisk (*).

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.

Encrypted code registration criteria table
The ignition key contains a transponder (small
transmitter), which retains an unique encrypted code.
Under any of the conditions below, the encrypted
code should be registered in the immobilizer-ECU
again. The immobilizer-ECU can retain maximum
eight different encrypted codes. This means that
maximum eight ignition keys can be registered.
