6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

GENERAL -Precautions Before Service00-5
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS), SEAT BELT WITH PRE-TENSIONER
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B - Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(3) Warning labels must be heeded when servicing or handling SRS components and seat belt with
pre-tensioner. Warning labels are located in the following locations.
DHood
DSun visor
DGlove box
DSRS-ECU
DSteering wheel
DSteering gearbox
DAir bag module (driver’s side and front passenger’s side)
DFront impact sensor
DClock spring
DSeat belt with pre-tensioner
DSide air bag module
DSide impact sensor
(4) Always use the designated special tools and test equipment.
(5) Store components removed from the SRS and seat belt with pre-tensioner in a clean and dry
place.
The air bag module and seat belt with pre-tensioner should be stored on a flat surface and
placed so that the pad surface is facing upward.
Do not place anything on top of it.
(6) Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock
spring and side impact sensor) and seat belt with pre-tensioner.
(7) Whenever you finish servicing the SRS and seat belt with pre-tensioner, check the SRS warning
lamp operation to make sure that the system functions properly.
(8) Be sure to deploy the air bag and seat belt with pre-tensioner before disposing of the air bag
module and seat belt with pre-tensioner or disposing of a vehicle equipped with an air bag and
seat belt with pre-tensioner. (Refer to GROUP 52B - Air Bag Module and Seat Belt with Pre-tensioner
Disposal Procedures.)
2. Observe the following when carrying out operations on places where SRS components and seat
belt with pre-tensioner are installed, including operations not directly related to the SRS air bag and
seat belt with pre-tensioner.
(1) When removing or installing parts do not allow any impact or shock to the SRS components
and seat belt with pre-tensioner.
(2) SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove
the SRS components and seat belt with pre-tensioner before drying or baking the vehicle after
painting.
DSRS-ECU, air bag module, clock spring, front and side impact sensors: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

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: front impact sensors, 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 (*).
