WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) 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 passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) 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-ECU, SRS warning lamp, 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 (*).

TROUBLESHOOTING
DIAGNOSIS FUNCTION
The power window and central door locking is controlled by the Smart Wiring System (SWS). For
troubleshooting, refer to GROUP 54B - Troubleshooting.
ON-VEHICLE SERVICE
DOOR ADJUSTMENT
1. If the gap between the door and body is inconsistent,
paste protection tape at the fender around the hinge
attached portion and at the door edge, use the special
tool to loosen the bolt fixing the door hinge at the body
side, and move the door to adjust so that the gap around
the door becomes consistent.
2. If steps exist between the door and body, use the special
tool to loosen the bolt fixing the door hinge at the door
side, and move the door and adjust the alignment of
the door surface.
Caution
Do not apply torque above 98 NSm for the special
tool (MB991164).

TROUBLESHOOTING
The windshield wiper-washer is controlled by the smart wiring system (SWS). Refer to Group 54B for
troubleshooting.
NOTE
If ETACS-ECU is faulty, the windshield wiper can be operable in LO mode only as the fail - safe function.
(Normally the windshield wiper is operable when the ignition switch is turned to the ACC position. When
the fail - safe function is enabled, it is operable only when the ignition switch is turned to the ON position.)
ON-VEHICLE SERVICE
WINDSHIELD INTERMITTENT WIPER
INSPECTIONS
(1) Check the change in the intermittent time of the wiper
operation by using the windshield intermittent wiper
volume.
(2) Carry out troubleshooting if any of them is faulty.
(Refer to Group 54B.)
