SUPPLEMENTAL RESTRAINT SYSTEM

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.

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 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 HANDLING A DEPLOYED AIR
BAG ASSEMBLY.  AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY

J–41433 SRS Driver/Passenger Load Tool

The SRS Driver/Passenger Load Tool J–41433 is used
only when called for in this section.  It is used as a
diagnostic aid and safety device to prevent inadvertent air
bag assembly deployment.
The load tool has four yellow connectors attached to its
case.
The three small connectors are electrically functional and
serve as resistive load substitutions.
No more than two connectors are used at any time.  One
of the small connectors is used to substitute for the load of
the driver air bag assembly when it is connected at the top
of the column to the SRS coil assembly.  Another small
connector is used to substitute for the load of the driver air
bag assembly and the SRS coil assembly when it is
connected at the base of the column to the SRS wiring
harness.  The third small connector is used to substitute
for the load of the passenger air bag assembly when
connected to the passenger air bag assembly harness
connector.
By substituting the resistance of the load tool when called
for, a determination can be made as to whether an inflator
circuit component is causing system malfunction and
which component is causing the malfunction.  The load
tool should be used only when specifically called for in the
diagnostic procedures.
