Tools Required

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.

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 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.

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 IP module, refer to Inflatable Restraint Instrument Panel Module Replacement .

•	If you are removing the side impact module - LF, refer to Inflatable Restraint Side Impact Module Replacement - Left Side .

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




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



6. Clear a space on the ground about 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 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.
8. When deploying a steering wheel inflator module, place the inflator module in the center of the space.



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

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

•	Fill the deployment fixture 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) in order to properly secure the IP module (1) to the deployment fixture.

•	Securely tighten all fasteners prior to deployment.




10. When deploying the side impact module - LF, refer to the following instructions:

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

•	Fill the deployment fixture with water or sand.

•	Mount the side impact module (1) in the deployment fixture (3) with the vinyl/plastic trim cover facing up.

•	Adjust and secure the J 39401-B arms (4) to the deployment fixture (3).

•	To mount, use 2 M 6 x 1.0 nuts (2) with washers in order to secure the side impact module (1) to the deployment fixture arms (4).

•	Securely tighten all fasteners prior to deployment.




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



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



15. 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 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.

16. Clear the area of people.



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



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

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




21. Seat 1 banana plug into the other in order to short the deployment harness leads.
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.



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

Caution: When deploying a SIR component for disposal, perform the deployment procedures in the order listed. Failure to observe the procedures in the order listed may result in personal injury.
