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.

TROUBLESHOOTING HINTS
•Malfunction of the immobilizer-ECU.
•Malfunction of the engine-ECU or
engine-A/T-ECU .
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. Check if MUT-II/III can communicate with
the MPI system and if an MPI system diagnosis
code other than P0513 is set.
Q: Can MUT-II/III communicate with the MPI system?
Is an MPI system diagnosis code other than P0513
set?
YES :
Go to Step 2.
NO : Refer to GROUP 13A, MPI Diagnosis
P.13A-15, GROUP 13B, MPI Diagnosis
P.13B-15.
STEP 2. Voltage measurement at
immobilizer-ECU connector C-202-1.
(1) Disconnect immobilizer-ECU connector C-202-1.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 1 and
earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 5.
NO : Go to Step 3.
STEP 3. Connector check: Immobilizer-ECU
connector C-202-1 and engine control relay
connector B-16X
Q: Are immobilizer-ECU connector C-202-1 and
engine control relay connector B-16X in good
condition?
YES :
Go to Step 4.
NO : Repair or replace the damaged
component(s). Confirm that MUT-II/III
