SUPPLEMENTAL RESTRAINT SYSTEM 9A-25

NOTE: When the air bag deploys, the driver air bag
assembly may jump about 30 cm (one foot) vertically.
This is a normal reaction of the driver air bag to the
force of the rapid gas expansion inside the air bag.

NOTE: When the air bag deploys, the rapid gas
expansion will create a substantial noise. Notify all
people in the immediate area that you intend to deploy
the driver air bag.

WARNING: THE DEPLOYMENT HARNESS SHALL
REMAIN SHORTED AND NOT BE 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.
CONNECTING THE DEPLOYMENT HARNESS TO
THE POWER SOURCE SHOULD ALWAYS BE THE
LAST STEP IN THE AIR BAG ASSEMBLY
DEPLOYMENT PROCEDURE. FAILURE TO
FOLLOW PROCEDURES IN THE ORDER LISTED
MAY RESULT IN PERSONAL INJURY.

16. Connect the SRS deployment harness wires to the

power source to immediately deploy the driver air
bag. Recommended application: 12 volts
minimum, 2 amps minimum. A vehicle battery is
suggested.

17. Disconnect the SRS deployment harness from the

power source.

18. Short the two SRS deployment harness leads

together by fully seating one banana plug into the
other.

19.

In the unlikely event that the driver air bag
assembly did not deploy after following these
procedures, proceed immediately with Steps 24
through 26. If 19. the driver air bag assembly did
deploy, proceed with Steps 20 through 23.

20. Put on a pair of shop gloves and safety glasses to

protect your hands and eyes from possible
irritation and heat when handling the deployed
driver air bag assembly. After the air bag assembly
has been deployed, the surface of the air bag may
contain a powdery residue. This power consists
primarily of cornstarch (used to lubricate the bag
as it inflates) and by-products of the chemical
reaction. Sodium hydroxide dust (similar to lye
soap) is produced as a by-product of the
deployment reaction. The sodium hydroxide then
quickly reacts with the atmospheric moisture and
is converted to sodium carbonate and sodium
bicarbonate (baking soda). Therefore, it is unlikely
that sodium hydroxide will be present after
deployment.

WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE VERY HOT. ALLOW THE INFLATOR
MODULE TO COOL BEFORE HANDLING ANY
METAL PORTION OF IT. DO NOT PLACE THE
DEPLOYED AIR BAG ASSEMBLY NEAR ANY
FLAMMABLE OBJECTS. FAILURE TO FOLLOW
PROCEDURES MAY RESULT IN FIRE OR
PERSONAL INJURY.

AFTER A DRIVER AIR BAG ASSEMBLY HAS BEEN
DEPLOYED, THE METAL CANISTER AND
SURROUNDING AREAS OF THE DRIVER AIR BAG
ASSEMBLY WILL BE VERY HOT. DO NOT TOUCH
THE METAL AREAS OF THE DRIVER AIR BAG
ASSEMBLY FOR ABOUT TEN MINUTES AFTER
DEPLOYMENT. IF THE DEPLOYED DRIVER AIR
BAG ASSEMBLY MUST BE MOVED BEFORE IT IS
COOL, WEAR GLOVES AND HANDLE BY THE AIR
BAG OR TRIM COVER.

21. Disconnect the pigtail adapter from the driver air

bag assembly as soon after deployment as
possible. This will prevent damage to the pigtail
adapter or SRS deployment harness due to
possible contact with the hot driver air bag
assembly canister. The pigtail adapter can be
reused. They should, however, be inspected for
damage after each deployment and replaced if
necessary.

22. Dispose of the deployed driver air bag assembly

through normal refuse channels after it has cooled
for at least 30 minutes.

23.

Wash your hands with mild soap and water
afterward.

NOTE: The remaining steps are to be followed in the
unlikely event that the driver air bag assembly did not
deploy after following these procedures.

24. 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.

25. Disconnect the pigtail adapter from the driver air

bag assembly.

WARNING: WHEN STORING A LIVE AIR BAG
ASSEMBLY OR WHEN LEAVING A LIVE
INFLATOR MODULE UNATTENDED ON A BENCH
OR OTHER SURFACE, ALWAYS FACE THE BAG
AND TRIM COVER 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.

26. Temporarily store the driver air bag assembly with

its trim cover facing up, away from the surface
upon which it rests.

Deployment Outside Vehicle (Passenger
Air Bag Assembly)

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.

Deployment out of the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which a functionally or
cosmetically deficient air bag assembly is replaced.
Deployment and disposal of an air bag assembly is, of
course, subject to any required retention period.

For deployment of a live air bag assembly out of the
vehicle, the deployment procedure must be followed
exactly. Always wear safety glasses during this
deployment procedure until the deployed air bag
assembly is scrapped. Before performing the
procedures, you should be familiar with servicing the
SRS system and with proper handling of the air bag
assembly. Procedures should be read fully before
they are performed.

The following procedure requires use of a 5-8840-
2468-0 SRS Deployment Harness with the appropriate
pigtail adapter. The procedure also requires the use
of a 5-8840-2420-0 Passenger Side SRS Module
Deployment Fixture. Do not attempt this procedure
without a 5-8840-2468-0 and adapter, and a 5-8840-
2420-0.

WARNING: FAILURE TO FOLLOW PROCEDURES
IN THE ORDER LISTED MAY RESULT IN
PERSONAL INJURY. NEVER CONNECT THE
DEPLOYMENT HARNESS TO ANY POWER
SOURCE BEFORE CONNECTING THE
DEPLOYMENT HARNESS TO THE AIR BAG
ASSEMBLY. THE DEPLOYMENT HARNESS SHALL
REMAIN SHORTED AND NOT BE 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 THROUGHOUT THIS ENTIRE
DEPLOYMENT AND DISPOSAL PROCEDURE.

NOTE: This information applies only to passenger air
bag assembly. Information for disposing of a live
driver air bag assembly can be found in “Deployment
Outside Vehicle” (Driver Air Bag Assembly) in this
section.

1. Turn the ignition switch to “LOCK”, remove the

key, and put on the safety glasses.

Inspect the 5-8840-2468-0 SRS Deployment
Harness and appropriate pigtail adapter for
damage. If the harness or pigtail is damaged,
discard and obtain a replacement.

3. Short the two SRS Deployment Harness leads

together by fully seating one banana plug into the
other. The SRS Deployment Harness shall remain
shorted and not be connected to a power source
until the air bag is to be deployed.

5. Remove the passenger air bag assembly from the

vehicle. Refer to “Passenger Air Bag Assembly
Removal “.

6. Clear a space on the ground approximately 183

cm (six feet) in diameter where the fixture with
attached air bag assembly is to be placed for
deployment. A paved outdoor location where there
is no activity is preferred. If an outdoor location is
not available, a space on the shop floor where
there is no activity and there is sufficient ventilation
is recommended. Ensure that no loose or
flammable objects are within the deployment area.

7. Place the 5-8840-2420-0 on the bench vise. This

is necessary to provide sufficient stabilization of
the fixture during deployment.

8. Attach the passenger air bag assembly in the 5-

8840-2420-0. The air bag assembly must be
mounted such that the bag will deploy upward.
SECURELY HAND–TIGHTEN ALL FASTENERS
PRIOR TO DEPLOYMENT.

9. Stretch the SRS Deployment Harness and pigtail

adapter from the air bag assembly to its full length.

10. Place a power source near the shorted end of the

SRS deployment harness. (Recommended
application: 12 volts minimum, 2 amps minimum.
A vehicle battery is suggested.)

11. Connect the air bag assembly to the pigtail adapter

on the SRS deployment harness. The SRS
Deployment Harness shall remain shorted and not
be 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.

NOTE: Ensure that the pigtail adapter is firmly seated
into the air bag assembly connector. Failure to fully
seat the connectors may leave the shorting bar located
in the air bag assembly connector functioning (shorting
the deployment circuit) and may result in no
deployment of the air bag assembly.

12. Verify that the area around the passenger air bag

assembly is clear of all people and loose or
flammable objects.

13. Verify that the passenger air bag assembly is

firmly and properly in the 5-8840-2420-0.

14. Notify all people in the immediate area of your

intention to deploy the passenger air bag
assembly. The deployment will be accompanied
by a substantial noise which may startle the
uninformed.

15.

Separate the two banana plugs on the SRS
deployment harness.

NOTE: When the air bag deploys, the rapid gas
expansion will create a substantial noise. Notify all
people in the immediate area that you intend to deploy
the air bag assembly.

16. Connect the SRS deployment harness wires to the

power source to immediately deploy the air bag
assembly. Recommended application : 12 volts
minimum, 2 amps minimum. A vehicle battery is
suggested.

17. Disconnect the SRS deployment harness from the

power source.

18.

Short the two SRS deployment harness leads

together by fully seating one banana plug into the
other.

19. In the unlikely event that the passenger air bag

assembly did not deploy after following these
procedures, proceed immediately with Steps 24
through 26. If the passenger air bag assembly
deployed as intended, proceed with Steps 20
through 23.

20.

The passenger inflator requires no special
precaution after deployment. 95% of the
particulate emission is potassium chloride (KLC),
which is commonly sold as an edible salt-
substitute. Even if water is applied, post
deployment products are relatively pH neutral.
Disposing of the inflator by burying it in a landfill
will not produce any hazardous products. As with
any dusty environment, safety goggles, dust mask
and gloves should be worn.

WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE HOT. ALLOW THE AIR BAG ASSEMBLY
TO COOL BEFORE HANDLING ANY METAL
PORTION OF IT. DO NOT PLACE THE DEPLOYED
INFLATOR MODULE NEAR ANY FLAMMABLE
OBJECTS. FAILURE TO FOLLOW PROCEDURES
MAY RESULT IN FIRE OR PERSONAL INJURY.
AFTER AN AIR BAG ASSEMBLY HAS BEEN
DEPLOYED, THE METAL CANISTER AND
SURROUNDING AREAS OF THE AIR BAG
ASSEMBLY WILL BE HOT. DO NOT TOUCH THE
METAL AREAS OF THE AIR BAG ASSEMBLY FOR
ABOUT THIRTY MINUTES AFTER DEPLOYMENT.
IF THE DEPLOYED AIR BAG ASSEMBLY MUST BE
MOVED BEFORE IT IS COOL, WEAR GLOVES AND
HANDLE BY THE AIR BAG ITSELF.

21. Disconnect the pigtail adapter from the air bag

assembly as soon after deployment as possible to
avoid damage to the pigtail adapter or SRS
deployment harness from contacting the hot air
bag assembly canister. The pigtail adapter and
SRS deployment harness are designed to be
reused. They should, however, be inspected for
damage after each deployment and replaced if
necessary.

22. Dispose of the deployed air bag assembly through

normal refuse channels after it has cooled for at
least 30 minutes.

23.

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.

24. 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.

25. 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.

26. 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 the 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 with the same VIN. Never use SRS
components from another vehicle.

1. Turn the ignition switch to “LOCK,” remove the key

and put on the safety glasses.

2. Remove all loose objects from the front seats.

3. Disconnect the driver air bag assembly yellow

connector located at the base of the steering
column.

4. Cut the driver air bag assembly yellow harness

connector from the vehicle leaving at least 15 cm
(six inches) of wire at the connector.
