Deployed Air Bag Assembly (Driver Side)
“You should wear gloves and glasses. After the air bag
assembly has been deployed, the surface of the air bag
may contain solid particulate. This solid particulate
c o n s i s t s p r i m a r i l y o f b y p r oducts of the chemical reaction,
Potassium Chloride and copper metal dust. Compounds
of Potassium Borate, Strontium Chloride, Copper
Chloride, and Ammonium Chloride may be found in
amounts of about 1% (each) of the total particulate.”
Deployed Pretensioner Seat Belt.
You should wear gloves and safety glasses. After the
pretensioner seat belt has been deployed, the surface of
the pretensioner seat belt cylinder may heating up.
Air Bag Assembly and/or Pretensioner
Seat Belt Scrapping Procedure.
During the cause of vehicle’s useful life, certain situations
may arise which will necessitate the disposal of a live air
bag and/or pretensioner seat belt. (This information
covers proper procedures for disposing of a live air bag
assembly and/or pretensioner seat belt.)
Before a live air bag assembly can be dispose off, it must
be deployed.
A live air bag assembly and/or pretensioner seat belt
must not be disposed of though normal refuse channels.
WARNING: FAILURE TO FOLLOW PROPER
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR
BAG ASSEMBLY DISPOSAL PROCEDURES CAN
RESULT IN AIR BAG DEPLOYMENT WHICH MAY
CAUSE PERSONAL INJURY. AN UNDPLOYED AIR
BAG ASSEMBLY MUST NOT BE DISPOSED OF
THROUGH NORMAL REFUSE CHANNELS. THE
UNDEPLOYED AIR BAG ASSEMBLY CONTAINS
SUBSTANCES THAT CAN CAUSE SEVERE ILLNESS
OR PERSONAL INJURY IF THE SEALED CONTAINER
IS DAMAGED DURING DISPOSAL. DISPOSAL IN
ANY MANNER INCONSISTENT WITH PROPER
PROCEDURES MAY BE A VIOLATION OF LOCAL
LAW.
In situations which require deployment of a live air bag
assembly, deployment may be accomplished inside or
outside the vehicle. The method employed depends
upon the final disposition of the particular vehicle, as
noted in “Deployment Outside Vehicle” and “Deployment
Inside Vehicle” in this section.
Cautions About Air Bag Deployment And
Disposal
Failure to follow proper procedures could result in
erroneous air bag deployment which may cause personal
injury be sure to follow proper procedures.
1. Turn off (Lock) the ignition switch and disconnect the
minus terminal of the battery, then start the work 15 or
more sec later. (Air bag is designed to work by the
back-up power source even if the battery power
source is cut off at vehicle collision).
2. Be sure not to disassemble the air bag.
3. Do not give an impact to the air bag and bring the air
bag close to magnet. (The air bag could deploy
unexpectedly).4. Place the air bag with its trim cover up.
5. Do not let the air bag deploy directly on the floor. (The
air bag may be blown off 2
3 m (6.5 or 10 feet)).
6. Be sure to install the air bag firmly to a deployment
tool (fixing tool).
7. Set a battery 10 m (33 feet) or more away from the air
bag.
8. Before disconnecting air bag harness, ground the
worker by touching the vehicle outer panel with bare
hand.
9. When connecting or disconnecting the harness, do
not work just in front of the air bag.
10. As deployment gives rise to big sound, warn the
people around against it. Further, try to reduce the
sound by covering the steering wheel or tires, and
shut the vehicle windows in case of deployment
inside the vehicle.
11. As deployment generates smoke, select a well
ventilated place. (In case of deployment indoors,
avoid deployment just under a fire alarm, smoke
sensor, and fluorescent lamps).
12. Be careful not to inhale the smoke after deployment.
13. If part of the vehicle glass is damaged, cover the
vehicle with a car cover to prevent the glass from
braking at the time of deployment.
14. Do not touch the air bag immediately after
deployment, since it remains hot for 30 minutes.
15. Do not water the air bag immediately after
deployment.
16. Wear safety glasses and gloves throughout the work
and wash the glasses and gloves after the work.
17. Do not reuse the removed air bag for another vehicle.
(Deployment characteristic is different with vehicle
types).
Deployment Outside Vehicle (Driver Air
Bag Assembly)
Deployment outside the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which the vehicle will be returned to
useful service after a functionally or cosmetically deficient
air bag assembly is replaced. Deployment and disposal
of a malfunctioning air bag assembly is, of course, subject
to any required retention period.
For deployment of a live (undeployed) air bag assembly
outside the vehicle, the deployment procedure must be
followed exactly. Always wear safety glasses during this
deployment procedure until a deployed air bag assembly
is scrapped or until an undeployed air bag assembly is
shipped. Before performing the procedures you should
be familiar with servicing the SRS and with proper
handling of the air bag assembly. Procedures should be
read fully before they are performed.
The following procedure requires use of 5–8840–2468–0
SRS deployment harness with appropriate pigtail
adapter. Do not attempt procedure without
5–8840–2468–0 adapter.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT

Service Precautions for SRS
Component Service
CAUTION: When fasteners are removed, always
reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use
the correct part number fastener for that application.
If the correct part number fastener is not available, a
fastener of equal size and strength (or stronger) may
be used. fasteners that are not reused, and those
requiring thread locking compound will be called
out. The correct torque value must be used when
installing fasteners that require it. If the above
conditions are not followed, parts or system damage
could result.
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver–Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned “OFF,” the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
“C–21” fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the “Disabling the SRS”
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to “OFF” and turn the steering
wheel so that the vehicle’s wheels are pointing straight
ahead.
1. Remove SRS fuse “C–21” from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2–pin connector at the base of
steering column.
3 . R e m o v e g l o v e b o x a s s e m b l y ; R e f e r t o “ P a s s e n g e r a i r

4. Disconnect passenger air bag assembly yellow 2–pin
connector behind the glove box assembly.
CAUTION: W i t h t h e “ C – 2 1 ” f u s e r e m o v e d a n d
ignition switch “ON,” the “AIR BAG” warning lamp
will be “ON.” This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to “LOCK” and remove key.
1. Connect yellow 2–pin connector passenger air bag
assembly.2. Install glove box assembly. Refer to “Passenger Air
Bag Assembly Replacement” in this section.
3. Connect yellow 2–pin connector at the base of the
steering column.
4. Install “AIR BAG” fuse “C–21” to left dash side lower
fuse block or connect battery.
Turn ignition switch to “ON” and verify that the “AIR BAG”
warning lamp turn on 3.5 seconds and then turns “OFF.” If
it does not operate as described, perform the “SRS
Diagnostic System Check” in this section.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the SDM pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as
this will set a diagnostic trouble code.
5. The “SRS Diagnostic System Check” must be the
starting point of any SRS diagnostics. The “SRS
Diagnostic System Check” will verify proper “AIR
BAG” warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
Inspections Required After An Accident
CAUTION: C e r t a i n S R S c o m p o n e n t s m u s t b e
replaced after a frontal crash involving air bag
deployment.
In all types of accidents regardless of “Air Bag”
deployment, visually inspect all of the following
components and replace as required:
— Driver air bag assembly
— Passenger air bag assembly
— Driver pretensioner assembly
— Passenger pretensioner assembly
— Steering wheel
— SRS coil assembly
— Steering column
— Knee bolster and instrument panel mounting
attachments
— Driver seat and belt
— Passenger seat and belt
—SDM
SDM always should be checked according to “SDM
Replacement Guidelines.”

SUPPLEMENTAL RESTRAINT SYSTEM9J–31
CAUTION: Refer to “SDM Replacement Guidelines”
below for important information on SDM
replacement in both deployment and
non–deployment crashes.
Inspect SRS coil assembly wiring and steering wheel for
any sign of scorching, melting, or damage due to
excessive heat. If coil assembly wire or steering wheel is
damaged, replace them. The steering column and wheel
must be dimensionally checked to determine if they are
damaged. Refer to steering wheel of in this manual.
Never use SRS parts from another vehicle. This does not
include remanufactured parts purchased from an
authorized Isuzu Retailer; they may be used for SRS
repairs.
Do not attempt to repair the SDM, the SRS harness, the
SRS coil assembly, the air bag assembly, the steering
wheel, or the steering column. Service of these items is
replacement only. Verify replacement part numbers.
CAUTION: Proper operation of the SDM and
supplemental restraint system (SRS) requires that
any repairs to the vehicle structure return it to its
original production configuration.
