GENERAL ± Precautions Before Service00-25
PRECAUTIONS BEFORE SERVICE00100050144
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
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) Always use the designated special tools and test equipment.
(3) 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.
(4) Never attempt to disassembly or repair the SRS components, (SRS diagnosis unit, air bag module
and clock spring). If faulty, replace it.
(5) Warning labels must be heeded when servicing or handling SRS components. Warning labels
are located in the following locations.

Hood

Sun visor

Glove box

SRS diagnosis unit

Steering wheel

Air bag module

Clock spring

Frame
(6) Store components removed from the SRS in a clean and dry place.
The air bag module 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.
(7) Be sure to deploy the air bag before disposing of the air bag module or disposing of a vehicle
equipped with an air bag. (Refer to GROUP 52B ± Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
2. Observe the following when carrying out operations on places where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over 93C, so remove the SRS components
before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to GROUP 52B ± SRS Maintenance.)
9. Make certain that the ignition switch is OFF when the MUT-II is connected or disconnected.
10. If you have any questions about the SRS, please contact your local distributor.
NOTE
SERIOUS INJURY CAN RESULT FROM UNINTENDED AIR BAG DEPLOYMENT, SO USE ONLY
THE PROCEDURES AND EQUIPMENT SPECIFIED IN THIS MANUAL.

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: impact sensors, SRS diagnosis unit, 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 (*).

THE PROCEDURES AND EQUIPMENT SPECIFIED IN THIS MANUAL.

SRS ± Troubleshooting52B-8
Code No. 21 or 22 Air bag module (squib) systemProbable cause
(1) These diagnosis codes are output if there is abnormal resistance between the
input terminals of the air bag module (squib).
The trouble causes for each code No. are as follows. (Refer to chart 1.)
(2) Diagnosis codes 21 and 22 are sometimes generated in combination with
malfunction codes relating to the front impact sensor (code Nos. 11, 12 and 13),
but sometimes only one may be output instead of both being memorized. Because
of this, the front impact sensor should also be inspected at the same time. The
relationships between the codes are as follows. (Refer to chart 2.)

Caution
Do not attempt to measure the air bag module (squib) circuit resistance. Use of a tester in measuring
the circuit resistance will supply current to the squib, or erroneous deployment due to static electricity
could cause serious injury.

SRS ± SRS Diagnosis Unit (SDU)/Air Bag Module and Clock Spring52B-28
INSPECTION52400220093

Check the SDU and brackets for dents, cracks or
deformation.

Check connector for damage, and terminals for
deformation.
Caution
If a dent, crack, deformation or rust is discovered,
replace the SDU with a new one.
NOTE
For checking of the SDU other than described above,
refer to the section concerning troubleshooting. (Refer
to P.52B-6.)
AIR BAG MODULE AND CLOCK SPRING52400240143
Caution
1. Disconnect the battery (±) terminal and wait
for 60 seconds or more before starting work.
Furthermore, the disconnected battery
terminal should be covered with tape to
insulate it. (Refer to P.52B-3, No.4.)
2. Never attempt to disassemble or repair the
air bag modules or clock spring.
If faulty, replace it.
3. Do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace it if a dent, crack, deformation or
rust is detected.4. The air bag modules 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.
5. Do not expose the air bag modules to
temperatures over 93C.
6. After deployment of an air bag, replace the
clock spring with a new one.
7. Wear gloves and safety glasses when
handling air bags that have already
deployed.
8. An undeployed air bag module should only
be disposed of in accordance with the
procedures (Refer to P.52B-34.)
