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.

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 (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 mayhave to be removed/installed in connectionwith SRS service or
maintenance) are indicated in the table of contents by an asterisk(*).

SRS -Post-collision Diagnosis52B-23
POST-COLLISION DIAGNOSIS
Whether or not the air bags have deployed, check and service
the vehicle after collision as follows:
SRS-ECU MEMORY CHECK
1. Connect the MUT-
IIto the diagnosis connector. (Refer
to GROUP 00 – How to Use Troubleshooting/Inspection
Service Points.)
Caution
Refer to that the ignition switch is LOCK(OFF) when
connecting or disconnecting MUT-II
.
2. Read (and write down) all displayed diagnosis codes.
(Refer to P.52B-7.)
NOTE
If battery power supply has been shut down by the
collision, the MUT-
IIcannot communicate with the
SRS-ECU. Check and, repair if necessary, the instrument
panel wiring harness before the next job.
3. Use the the MUT-
IIto read the data list (how long trouble(s)
have continued and how often memory have been
erased).
Data list
NoService Data ItemApplicability
92Number indication how often the memory is cleared.Maximum time to be stored: 250
93How long problem have lasted (How long it takes
from the occurrence of the problem till the first air bag
squib igniting signal)Maximum time to be stored: 9999 minutes
(approximately 7 days)
94How long problem(s) have lasted (How long it takes
from the first air bag squib igniting signal till now.)
4. Erase the diagnosis codes and after waiting 5 seconds
or more read (and write down) all displayed diagnosis
codes. (Refer to P.52B-7.)
REPAIR PROCEDURE
DEPLOYED DRIVER’S AND FRONT PASSENGER’S AIR
BAGS
1. Replace the following parts with new ones.
DSRS-ECU (Refer to P.52B-30.)
DDriver’s air bag module (Refer to P.52B-32.)
DFront passenger’s air bag module (Refer to P.52B-32.)
2. Check the following parts and replace if malfunction is
found:
DClock spring (Refer to P.52B-32.)
DSteering wheel, steering column and intermediate
joint
(1) Check the wiring harness (built into steering
wheel) and connectors for damage, and terminals
for deformation.
(2) Check the driver’s air bag module for proper
installation to the steering wheel.
