Warning: Refer to SIR Inflator Module Handling and Storage Warning in the Preface section.

Take special care when handling or storing an undeployed inflator module. An inflator module deployment produces a rapid generation of gas. This may cause the inflator module, or an object in front of the inflator module, to project through the air in the event of an unlikely deployment.

Dual stage inflator modules have two deployment stages. If stage 1 was used to deploy a dual stage inflator module, stage 2 may still be active. Therefore, a deployed dual stage inflator module must be treated as an active module. If disposal of a dual stage module is required, both deployment loops must be energized to deploy the air bag.

During the course of a vehicle's useful life, certain situations may arise which will require the disposal of a live and undeployed inflator module. Do NOT dispose a live and undeployed inflator module through normal disposal channels until the inflator module has been deployed.

Do not deploy the inflator module in the following situations:

You can deploy the inflator module either inside or outside of the vehicle. The method used depends upon the final disposition of the vehicle. Review the following procedures in order to determine which will work best in a given situation:

Deploy the inflator module outside of the vehicle when the vehicle will be returned to service. Situations that require deployment outside of the vehicle include the following:

Deployment and disposal of a malfunctioning inflator module is subject to any required retention period.

Warning: Refer to SIR Inflator Module Disposal Warning in the Preface section.

1. Turn OFF the ignition.

Warning: Refer to SIR Inflator Module Handling and Storage Warning in the Preface section.

2. Remove the inflator module.



3. Clear a space on the ground about 1.85 m (6 ft) in diameter for deployment of the inflator module or deployment fixture. If possible, use a paved, outdoor location free of activity. Otherwise, use a space free of activity on the shop floor. Ensure you have sufficient ventilation.
4. Clear the area of loose or flammable objects.

Note: Dual stage deployments are only used in steering wheel and I/P inflator modules. If stage 1 was used to deploy a dual stage inflator module, stage 2 may still be active. If disposal of a dual stage module is required, both deployment loops must be energized to deploy the air bag.

5. If you are deploying a steering wheel inflator module, place the inflator module in the center of the space with the vinyl trim cover facing up and away from the surface.



6. When deploying an I/P inflator module, perform the following instructions:

6.1.	Place the J 39401-B or SA9413NE in the center of the cleared area.

6.2.	Fill the deployment fixture with water or sand.

6.3.	Using the proper nuts and bolts, mount the I/P module (1) to the deployment fixture (2), with the vinyl trim facing up.

6.4.	Securely tighten all fasteners that hold the I/P module (1) to the deployment fixture (2).




7. When deploying a roof rail module, perform the following instructions:

7.1.	Place the J 39401-B or SA9413NE (3) in the center of the cleared area.

7.2.	Fill the deployment fixture with water or sand to provide sufficient stabilization of fixture during deployment.

7.3.	Adjust and secure the fixture arms (4) to the deployment fixture (3), using the proper nuts and bolts.

7.4.	Attach the roof rail module in the deployment fixture and securely tighten all fasteners.




8. Inspect the J 38826 or SA9207Z-A and the appropriate pigtail adapter (2) for damage. Replace as needed.
9. Short the 2 SIR deployment harness leads (1) together using one banana plug seated into the other.
10. Connect the appropriate pigtail adapter (2) to the SIR deployment harness (1).



11. Extend the SIR deployment harness and adapter to the full length from the deployment fixture or area.

Note: On a dual stage inflator module, both connectors must be attached to the deployment harness adapter. This will ensure that both stage 1 and stage 2 of the deployment loops are energized, regardless of the deployment state.




12. Connect the inflator module (1) to the adapter (2) on the SIR deployment harness (3).

Note: 

•	The rapid expansion of gas involved with deploying an inflator module is very loud. Notify all the people in the immediate area that you intend to deploy the inflator module.

•	When the inflator module deploys, the deployment fixture may jump about 30 cm (1 ft) vertically. This is a normal reaction of the inflator module due to the force of the rapid expansion of gas inside the inflator module.

•	If you are deploying a dual stage inflator module with stage 1 already deployed, the fixture may not move and the noise may have been reduced.

13. Clear the area of people.



14. Separate the 2 banana plugs on the SIR deployment harness that were shorted together earlier in the procedure.



15. Place a 12V minimum/2A minimum power source, such as a vehicle battery, near the shorted end of the harness.
16. Connect the SIR deployment harness wires to the power source. Deployment of the Inflator module will occur when contact is made.



17. Disconnect the SIR deployment harness from the power source after the inflator module deploys.
18. If the inflator module did not deploy, disconnect the adapter and discontinue the procedure and contact the Technical Assistance Group.

If deployment was successful, proceed to the following steps.

Warning: Refer to SIR Deployed Inflator Modules Are Hot Warning in the Preface section.

19. Seat one banana plug into the other in order to short the deployment harness leads.
20. Put on a pair of shop gloves.
21. Disconnect the pigtail adapter from the inflator module as soon as possible.
22. Inspect the pigtail adapter and the SIR deployment harness. Replace as needed.
23. Dispose of the deployed inflator module through normal refuse channels.
24. Wash your hands with a mild soap.

Deploy the inflator modules inside of the vehicle when destroying the vehicle or when salvaging the vehicle for parts. This includes, but is not limited to, the following situations:

Warning: Refer to SIR Inflatable Module Deployment Outside Vehicle Warning in the Preface section.

1. Lower the driver and passenger windows.
2. Turn the ignition switch to the OFF position and remove the ignition key.
3. Check that all inflator modules which will be deployed are mounted securely.
4. Remove all loose objects from the front seats.

Warning: A deployed dual stage inflator module will look the same whether on or both stages were used, always assume a deployed dual stage inflator module has an active stage 2. Improper handling or servicing can activate the inflator module and cause personal injury.
