REAR WIPER AND WASHER
GENERAL INFORMATIONM1511000100525
REAR WIPER AND WASHER OPERATION
Rear Wiper Operation
•If the rear wiper and washer switch is turned to
"INT" position with the ignition switch at "ACC" or
"ON" position, the ETACS-ECU turns ON the rear
wiper drive signal for three seconds
(approximately two cycles), then 7.4 seconds
later the intermittent motion operates every eight
seconds. If the selector lever is moved to the "R"
position when the rear wiper and washer switch is
turned to the "INT" position and the ignition
switch is at the "ACC" or "ON" position, the inhibitor switch "R" turns ON. One second later,
the ETACS-ECU turns ON the rear wiper drive
signal for three seconds (approximately two
cycles). Then, 7.4 seconds later, the intermittent
motion of eight seconds' cycle is restored.
Rear Washer Operation
•If the rear wiper and washer switch is turned to
the ON (washer) position with the ignition switch
at the "ACC" or "ON" position, the rear washer
ON signal is sent to the ETACS-ECU, causing the
rear wiper signal to turn on after 0.3 second. After
the rear washer switch signal turns off, the rear
wiper signal turns off in three seconds. If the rear
washer switch is turned to the ON position while
the rear wiper is in intermittent mode, the rear
washer works for that period when the washer
switch remains on. Then the rear wipers return to
the intermittent mode.
SERVICE SPECIFICATIONM1511000300336
TROUBLESHOOTINGM1511000700334
The rear wiper and washer are controlled by the
Smart Wiring System (SWS). For troubleshooting,
refer to GROUP 54B, Troubleshooting P.54B-17 or
GROUP 54C, Troubleshooting P.54C-4.

CHECK OF REAR WIPER OPERATION
WHEN SELECTOR LEVER IS AT THE "R"
POSITION
1. When the selector lever is moved to the "R"
position with the rear wiper switch at the "INT"
position, the wiper should operate twice or three
times at low speed after approximately one
second.
2. If not, carry out the troubleshooting (Refer to
GROUP 54B, Troubleshooting P.54B-17 or
GROUP 54C, Troubleshooting P.54C-4). ItemStandard value

DOOR MIRROR
GENERAL INFORMATIONM1511000100536
DOOR MIRROR OPERATION
Remote Controlled Mirror Operation
•The mirror on the door mirror moves up/down
and left/right by operating the remote controlled
door mirror switch when the ignition switch is in
the "ON" or "ACC" position.Heated Door Mirror operation
•The defogger relay switch is activated (ON) by
turning on the A/C-ECU built-in defogger switch
when the ignition switch is in the "ON" position.
When the defogger relay is turned ON, power is
supplied to the defogger and door mirror, and the
heater of the door mirror (heated door mirror)
starts operations. The defogger comes with a
timer function and will automatically turn OFF the
switch approximately 11 minutes after the
defogger switch is turned ON. The heated door
mirror operations are also terminated along with
the defogger, at this time.

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 (*).

DIAGNOSIS PROCEDURE
STEP 1. Check for presence of other key near the
key in the ignition.
Q: Is there any other key near the key in the ignition?
YES :
Move the other key well away from key
being used. Retest the system.
NO : Go to Step 2.
STEP 2. Check that the engine start using the
spare ignition key which encrypted code has
been registered.
Q: Does the engine start using the spare ignition key
for which the encrypted code has been registered?
YES :
Replace the ignition key that does not work.
Then register the password (secret code)
and encrypted code P.54A-20. Retest the
system.
NO : Go to Step 3.
STEP 3. Check whether the diagnosis code is
reset.
Q: Which diagnosis code is set, code No.11 or 12 the
encrypted code has been registered?
Code No.12 is set :
Refer toP.54A-11.
Code No.11 is set : Go to Step 4.
STEP 4. Connector check: Immobilizer-ECU
connector C-202-1.
Q: Are immobilizer-ECU connector C-202-1 in good
condition?
YES :
Replace immobilizer-ECU and Then
register the password (secret cod) and
encrypted code P.54A-20. Retest the
system.
NO : Repair or replace the damage
component(s).
Code No.12: Encrypted Codes are Not identical or not Registered
DIAGNOSIS CODE SET CONDITION
The encrypted code sent by the transponder is not
the same encrypted code which is registered in the
immobilizer-ECU.
NOTE: Diagnosis code No.12 is always set together
with MPI system diagnosis code No.P0513.
TROUBLESHOOTING HINTS
•The encrypted code in the ignition key has not
been properly registered.•Malfunction of immobilizer-ECU.
DIAGNOSIS PROCEDURE
Was the encrypted code registered?
YES :
Replace the immobilizer-ECU and then
re-register the encrypted code (Refer to
P.54A-20).
NO : Register the encrypted code (Refer to
P.54A-20).

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 :

NO : Repair or replace the damaged
component(s). Confirm that MUT-II/III
communicates normally.
STEP 10. Replace the immobilizer-ECU or
engine-ECU or engine-A/T-ECU .
Replace the immobilizer-ECU.
Q: Did the communication with MUT-II/III become
possible after replacing the immobilizer-ECU?
YES :
Register the password (secret code) and
encrypted code P.54A-20. Confirm that
MUT-II/III communicates normally
NO : Go to Step 11.
STEP 11. Recheck for malfunction.
Q: Is a malfunction eliminated?
YES :
The procedure is complete. If no
malfunctions are found in all steps, an
intermittent malfunction is suspected (Refer
