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

Take special care when handling or storing a live (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 2 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 deployed or undeployed dual stage module is required, both deployment loops must be energized to deploy the air bag.

During the course of a vehicles useful life, certain situations may arise which will require the disposal of a live (undeployed) inflator module. Do not dispose a live (undeployed) inflator module through normal disposal channels until the inflator module has been deployed. The following information covers the proper procedures for the disposing of a live (undeployed) inflator module.

Do not deploy the inflator module in the following situations:

The inflator module 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:

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

•	If you are removing the instrument panel (I/P) module, refer to Inflatable Restraint Instrument Panel Module Replacement .

•	If you are removing a side impact module, refer to Driver and Passenger Seat Side Inflatable Restraint Module Replacement .

•	If you are removing a roof rail module, refer to Inflatable Restraint Roof Side Rail Module Replacement .

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




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



6. 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. 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 a dual stage 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. If you have a steering wheel inflator module, place the inflator module in the center of the space.



9. If you have an I/P inflator module, refer to the following instructions:

9.1.	Place the J 39401-B SIR deployment fixture (2) in the center of the cleared area.

9.2.	Fill the deployment fixture with water or sand.

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

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




10. If you have a side impact module, refer to the following instructions:

10.1.

Place the J 39401-B SIR deployment fixture (3) in the center of the cleared area.

10.2.

Fill the deployment fixture with water or sand.

10.3.

Using the proper nuts and mount the side impact module (1) to the deployment fixture (3), with the vinyl trim facing up.

10.4.

Adjust and secure the fixture arms (4) to the deployment fixture (3).

10.5.

Securely tighten all fasteners that hold the side impact module (1) to the deployment fixture (3).




11. If you have a roof rail module, refer to the following instructions:

11.1.

Place the J 39401-B SIR deployment fixture (3) in the center of the cleared area.

11.2.

Fill the deployment fixture with water or sand.

11.3.

Using the proper nuts (2) and mount the roof rail module (1) to the deployment fixture (3), with the vinyl face up.

11.4.

Adjust and secure the fixture arms (4) to the deployment fixture (3).

11.5.

Securely tighten all fasteners that hold the side impact module (1) to the deployment fixture (3).




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

Important: Refer to Tools Required list for the correct adapter.

14. Connect the appropriate pigtail adapter (2) to the SIR deployment harness (1).



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




Important: 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.

16. Connect the inflator module to the adapter (2) on the SIR deployment harness (1).
17. Place a 12 V minimum/2 A minimum power source (i.e., vehicle battery) near the shorted end of the harness.

Important: 

•	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.

18. Clear the area of people.



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



20. Connect the SIR deployment harness wires to the power source. Inflator module deployment will occur when contact is made.



21. Disconnect the SIR deployment harness from the power source after the inflator module deploys.
22. If the inflator module did not deploy, disconnect the adapter and discontinue the procedure. Contact the Technical Assistance Group. Otherwise, proceed to the following steps.

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

24. Put on a pair of shop gloves.
25. Disconnect the pigtail adapter from the inflator module as soon as possible.
26. Inspect the pigtail adapter and the SIR deployment harness. Replace as needed.
