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

Use special care when handling or storing live, undeployed, inflator modules. 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 the 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 deployed or undeployed 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, undeployed, inflator module. Do not dispose of a live, undeployed, inflator module through normal disposal channels until the inflator module has been deployed. The following information covers the proper procedures for disposing of a live, undeployed, inflator module.

Do not deploy an inflator module in the following situations:

Inflator modules can be deployed 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.

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

Tools Required

1. Turn OFF the ignition.
2. Remove the ignition key.
3. Put on safety glasses.
4. Remove the inflator module. Refer to the following:

•	When removing the steering wheel module, refer to Inflatable Restraint Steering Wheel Module Replacement .

•	When removing the I/P module, refer to Inflatable Restraint Instrument Panel Module Replacement .




5. Place the inflator module with the vinyl trim cover facing up and away from the surface on a work bench, floor or deployment fixture.



6. Clear an area on the floor approximately 1.85 m (6 ft) in diameter for deployment of the inflator module. If possible, use a paved, outdoor location free of activity. Otherwise, use an area free of activity on the shop floor. Make sure you have sufficient ventilation.
7. Make sure no loose or flammable objects are in the area.

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

8. When deploying a steering wheel module, place the steering wheel module in the center of the cleared area.



9. When deploying an I/P module, refer to the following instructions:

•	Place the J 39401-B  (2) in the center of the cleared area.

•	Fill the deployment fixture (2) with water or sand.

•	Mount the I/P module (1) in the deployment fixture (2) with the vinyl/plastic trim facing up.

•	To mount, use 4 M 6 bolts (6), nuts (8), and washers (7) to properly secure the I/P module (1) to the deployment fixture (2).

•	Tighten all fasteners prior to deployment.




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



13. Extend the SIR deployment harness and adapter to full length from the deployment fixture.



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

Important: 

•	The rapid expansion of gas involved with deploying an inflator module is very loud. Notify all people in the immediate area that an inflator module will be deployed.

•	When the inflator module deploys, the deployment fixture may jump vertically. This is a normal reaction of the inflator module due to the force of the rapid expansion of gas inside the inflator module.

15. Clear the area of people.



16. Separate the 2 banana plugs on the SIR deployment harness.



17. Place a 12 V minimum/2 A minimum power source, i.e. vehicle battery, near the shorted end of the SIR deployment harness.
18. Connect the SIR deployment harness wires to the power source. Inflator module deployment will occur when contact is made.
19. Disconnect the SIR deployment harness from the power source.

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




20. Seat 1 banana plug into the other in order to short the deployment harness leads.
21. If the inflator module did not deploy, disconnect the adapter and discontinue the procedure. Contact the Technical Assistance Group for further assistance. Otherwise, proceed to the following steps.



22. Put on a pair of shop gloves.
23. Disconnect the pigtail adapter from the inflator module as soon as possible.
24. Dispose of the deployed inflator module through normal refuse channels.
25. Wash hands with a mild soap.
