WARNING: IF SO EQUIPPED WITH A
SUPPLEMENTAL RESTRAINT SYSTEM (SRS),
REFER TO THE SRS COMPONENT AND WIRING
LOCATION VIEW IN ORDER TO DETERMINE
WHETHER YOU ARE PERFORMING SERVICE ON OR
NEAR THE SRS COMPONENTS OR THE SRS
WIRING. WHEN YOU ARE PERFORMING SERVICE
ON OR NEAR THE SRS COMPONENTS OR THE SRS
WIRING, REFER TO THE SRS SERVICE
INFORMATION. FAILURE TO FOLLOW WARNINGS
COULD RESULT IN POSSIBLE AIR BAG
DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When

SUPPLEMENTAL RESTRAINT SYSTEM 9J–2
General Description
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.
Restraint Devices
827RW006
Legend
(1) Deployed Air Bag
(2) Knee Bolster
(3) Seat Belt
The Supplemental Restraint System (SRS) helps
supplement the protection offered by the driver and front
passenger seat belts by deploying an air bag from the
center of the steering wheel and from the top of the right
side of the instrument panel.
The air bag deploys when the vehicle is involved in a
frontal crash of sufficient force up to 30 degrees off the
centerline of the vehicle. To further absorb the crash
energy there is a knee bolster located beneath the
instrument panel for both the driver and passenger, and
the steering column is collapsible.

SUPPLEMENTAL RESTRAINT SYSTEM9J–5
1. Energy Reserve — The SDM maintains 24–Volt Loop
Reserve (24VLR) energy supply to provide
deployment energy when ignition voltage is lost in a
frontal crash.
2. Frontal Crash Detection — The SDM monitors
vehicle velocity changes to detect frontal crashes
which are severe enough to warrant deployment.
3. Air Bag Deployment — When a frontal crash of
sufficient force is detected, the SDM will cause
enough current to flow through the air bag assembly
to deploy the air bag.
4. Malfunction Detection — The SDM performs
diagnostic monitoring of SRS electrical components
and sets a diagnostic trouble code when a
malfunction is detected.
5. Frontal Crash Recording — The SDM records
information regarding SRS status during frontal
crash.
6. Malfunction Diagnosis — The SDM displays SRS
diagnostic trouble codes and system status
information through the use of a scan tool.
7. Driver Notification — The SDM warns the vehicle
driver of SRS malfunctions by controlling the “Air
Bag” warning lamp.
The SDM is connected to the SRS wiring harness by a
24–pin connector. This harness connector uses a
shorting clip across certain terminals in the contact area.
This shorting clip connects the “AIR BAG” warning lamp
to ground when the SDM harness connector is
disconnected or CPA (Connector Position Assurance) is
not inserted even if completely connected. This will
cause the “AIR BAG” warning lamp to come “ON” steady
whenever the ignition switch is at the ON or START
positions with the SDM disconnected.

Legend
(1) SDM
(2) SRS Harness
(3) Connector Position Assurance
“Air Bag” Warning Lamp
Ignition voltage is applied to the “AIR BAG” warning lamp
when the ignition switch is at the ON or START positions.
The SDM controls the lamp by providing ground with a
lamp driver. The “AIR BAG” warning lamp is used in the
SRS to do the following:
1. Verify lamp and SDM operation by turn on 3.5
seconds and then turns “OFF” when the ignition
switch is first turned “ON”.
2. Warn the vehicle driver of SRS electrical system
malfunctions which could potentially affect the
operation of the SRS. These malfunctions could
result in nondeployment in case of a frontal crash or
deployment for conditions less severe than intended.
The “AIR BAG ” warning lamp is the key to driver
notification of SRS malfunctions. For proper lamp
operation, refer to the “SRS Diagnostic System Check” in
this section.
821RW037
SRS Coil Assembly
The SRS coil assembly consists of two current carrying
coils. This is attached to the steering column and allow
rotation of the steering wheel while maintaining
continuous contact of the driver deployment loop to the
driver air bag assembly.
There is a shorting clip on the yellow 2–pin connector near
the base of steering column which connects the SRS coil
to the SRS wiring harness.
The shorting clip shorts to the SRS coil and driver air bag
assembly when the yellow 2–pin connector is
disconnected. The circuit to the driver air bag assembly is
shorted in this way to help prevent unwanted deployment
of the air bag when servicing the steering column or other
SRS components.
Page 3443 of 6000
SUPPLEMENTAL RESTRAINT SYSTEM 9J–6
825RS017
Air Bag Assemblies
The air bag assembly consist of an inflatable air bag
assembly and an inflator (a canister of gas–generating
material and an initiating device). When the vehicle is in a
frontal crash of sufficient force.
The SDM causes current flow through the deployment
loops. Current passing through the inflator ignites the
material in the air bag assembly. The gas produced from
this reaction rapidly inflates the air bag assembly.
There is a shorting clip on the driver air bag assembly
connector which connects the SRS coil assembly. The
shorting clip shorts across the driver air bag assembly
circuits when driver air bag assembly connector is
disconnected.
The circuit to the driver air bag assembly is shorted in this
way to help prevent unwanted deployment of the air bag
when servicing the driver air bag assembly, the steering
column or other SRS components.
827RS008There is a shorting clip on the passenger air bag
assembly connector which connects to the SRS harness.The shorting clip shorts across the passenger air bag
assembly circuit when the passenger air bag assembly
connector is disconnected. The circuit to the passenger
air bag assembly is shorted in this way to help prevent
unwanted deployment of the air bag when servicing the
passenger air bag assembly, the instrument panel or
other SRS components.
827RS001
Seat Belt with Pretensioner (If so
equipped)
The seat belt comprises a seat belt and a cylinder (a
cylinder filled with powder and an ignition device). In
cases of frontal collision which cause a shock exceeding
a specified level, the controller lets current flow to the
inflation circuit. The current ignites the cylinder of the seat
belt, producing gas. The gas helps tighten the seat belt to
restrain firmly the driver’s upper half in his seat.

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

13. Wash your hands with mild soap and water afterward.
NOTE: The remaining steps are to be followed in the
unlikely event that the air bag assembly did not deploy
after following the above procedures.
14. Ensure that the SRS deployment harness has been
disconnected from the power source and that its two
banana plugs have been shorted together by fully
seating one banana plug into the other.

15. Disconnect the pigtail adapter from the air bag
assembly.
WARNING: WHEN STORING A LIVE AIR BAG
ASSEMBLY OR WHEN LEAVING A LIVE AIR BAG
ASSEMBLY UNATTENDED ON A BENCH OR OTHER
SURFACE, ALWAYS FACE THE BAG UP AND AWAY
FROM THE SURFACE. THIS IS NECESSARY SO
THAT A FREE SPACE IS PROVIDED TO ALLOW THE
AIR BAG TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. FAILURE TO FOLLOW
PROCEDURES MAY RESULT IN PERSONAL INJURY.
16. Temporarily store the air bag assembly with the bag
facing up, away from the surface upon which it rests.

Deployment Inside Vehicle (Vehicle
Scrapping Procedure)
Deployment inside vehicle is proper when the vehicle is to
be destroyed or salvaged for component parts. This
includes, but is not limited to, the following situations:
1. The vehicle has completed its useful life.
2. The vehicle has been damaged beyond repair in a
nondeployment type accident.
3. The vehicle has been stripped or damaged beyond
repair in a theft.
4. The vehicle will be salvaged for component parts to
be used on a vehicle with a different Vehicle
Identification Number (VIN) as opposed to being
rebuilt as same VIN. Never use SRS components
from another vehicle.
WARNING: FAILURE TO FOLLOW PROPER SRS AIR
BAG ASSEMBLY DISPOSAL PROCEDURES CAN
RESULT IN AIR BAG DEPLOYMENT WHICH MAY
CAUSE PERSONAL INJURY. UNDEPLOYED AIR
BAG ASSEMBLIES 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 FEDERAL,
STATE AND/OR LOCAL LAWS.
1. Turn ignition switch to “LOCK,” remove key and put
on safety glasses.
2. Remove all loose objects from front seats.
3. Disconnect driver air bag assembly, yellow 2–pin
connector located at the base of the steering column.
4. Cut the driver air bag assembly yellow 2–pin harness
connector from the vehicle leaving at least 15 cm (six
inches) of wire at the connector.
5. Strip 13 mm (1/2 inch) of insulation from yellow –
green and yellow – black wire lead of the connector.
6. Cut two 900 cm (30 feet) deployment wires from 0.8
mm
(18 gauge) or thicker multi–strand wire. These
wires will be used to fabricate the driver deployment
harness.
7. Strip 13 mm (1/2 inch) of insulation from both ends of
the wires cut in the previous step.
8. Short the wires by twisting together one end from
each. Deployment wires shall remain shorted and not
be connected to a power source until the air bag is to
be deployed.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED COULD RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT WIRES
TO ANY POWER SOURCE BEFORE CONNECTING
DEPLOYMENT WIRES TO THE AIR BAG ASSEMBLY
LEADS. DEPLOYMENT WIRES SHALL REMAIN
SHORTED AND BE NOT CONNECTED TO A POWER
SOURCE UNTIL THE AIR BAG IS TO BE DEPLOYED.
THE AIR BAG ASSEMBLY WILL IMMEDIATELY
DEPLOY THE AIR BAG WHEN A POWER SOURCE IS
CONNECTED TO IT. WEAR SAFETY GLASSES
