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 J–42986 SRS
Deployment Harness with the appropriate pigtail adapter.
The procedure also requires the use of J–41497
Passenger Side SRS Module Deployment Fixture. Do
not attempt this procedure without J–42986 and fixture
J–41497.

WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT
HARNESS TO ANY POWER SOURCE BEFORE
CONNECTING DEPLOYMENT HARNESS TO THE AIR
BAG ASSEMBLY. 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 ignition switch to “LOCK” remove key, and put on

safety glasses.

2. Inspect J–41434 SRS Deployment Harness and

appropriate pigtail adapter for damage. If 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.

4. Connect the appropriate pigtail adapter to the SRS

Deployment Harness

827RS004

5. Remove passenger air bag assembly from vehicle.

Refer to “Passenger Air Bag Assembly Removal ” in
this Section.

6. Clear a space on the ground approximately 185 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 is no activity and
sufficient ventilation is recommended. Ensure that no
loose or flammable objects are within the deployment
area.

7. Place the J–41497 on the bench vice. This is

necessary to provide sufficient stabilization of the
fixture during deployment.

8. Attach the passenger air bag assembly in the

J–41497. 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 non 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.

9J–15

13. Verify that the passenger air bag assembly is firmly

and properly in J–41497.

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 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.

WARNING: 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 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. 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 air bag
assembly. After the air bag assembly has been
deployed, the surface of the air bag may contain a
powdery residue. This powder 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 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 for very
long after deployment.

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 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 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

non deployment 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.
