Step 14. Measure the voltage at the E-02 door
mirror assembly (LH) connector.
(1) Turn the ignition switch to the ON position.
(2) Rear window defogger switch: ON
(3) Disconnect the connector, and measure at the
wiring harness side.
(4) Voltage between E-02 door mirror assembly
connector terminal No.1 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00 − How to Cope with Intermittent
Malfunction P.00-5).
NO : Go to Step 15.
Step 15. Check the wiring harness between E-02
door mirror assembly (LH) connector terminal
No.1 and C-212 junction block connector
terminal No.3.
•Check the power supply line for open circuit.
NOTE:
Prior to the wiring harness inspection, check
intermediate connector C-29 , C-113
and repair if necessary.
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00 − How to Cope with Intermittent
Malfunction P.00-5).
NO : Repair the wiring harness.

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 (*).

IGNITION SWITCH
CHASSIS ELECTRICAL54A-6
IGNITION SWITCH
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.

Dimmer interior lamp control function
The room lamp off is delayed by ETACS-ECU. The
lamps off delay time vary according to the conditions.
The control details are as follows. The lamp delay off
Yes/NO and delay time can be set with the settings
(adjustment function). for adjustment methods and
adjustment details (post-adjustment operations).
•ADJUSTMENT PROCEDURE
•Not using SWS monitor: GROUP 54B,
P.54B-423.
•The room lamp lights up if the ignition switch is at
the "LOCK" (OFF) position and either of the
doors are opened (either of the door switches:
ON). At this time, if all doors are closed (all door
switches: OFF) then the lamp will gradually dim
down to lamps off in about 15 seconds.
NOTE: When the lamps are dimmed and the ignition
switch is turned ON or if the door is locked, then
the dimming operations stop and the lamps are
turned OFF.
•When the ignition switch is at the ON position and
one of the doors are opened (one of the door
switches: ON) then the room lamp will light up. At
this time, if all doors are closed (all door switches:
OFF) then the lamps will dim out.
•When the ignition key is pulled out the room lamp
lights up and then will dim out in 15 seconds. The
lamp will dim out if the ignition key is inserted
again and the door is locked while the timer is
activated.
The room lamp is controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.•Not using SWS monitor: GROUP 54B, SWS

Interior lamp automatic shutdown
function system>
The interior lamp automatic shutdown function, dims
out the room lamp and other interior lamps by
activating the keep relay built-in the ETACS-ECU
when the ignition switch is OFF and the
multi-purpose fuse loaded signals built-in the
ETACS-ECU is ON and 30 minutes passes. The
lamps lights back up if the ignition switch is turned to
the ON position or either of the doors is opened
(either of the door switches: ON). The function
Yes/No feature can be changed with the settings
(adjustment function). for adjustment methods and
adjustment details (post-adjustment operations).
