Deployment Outside Vehicle (Steering Wheel Module, I/P Module, and Roof Rail Module)

DEPLOYMENT OUTSIDE VEHICLE (STEERING WHEEL MODULE, I/P MODULE, AND ROOF RAIL MODULE)

Deploy the inflator module outside of the vehicle when the vehicle will be returned to service. For seat belt pretensioner deployment outside of the vehicle, refer to Pretensioner Handling and Scrapping. Situations that require deployment outside of the vehicle include the following:
- Using the SIR diagnostics, determine that the inflator module is malfunctioning.
- The inflator module is cosmetically damaged, scratched, or ripped.
- The inflator module pigtail (if equipped) is damaged.
- The inflator module connector is damaged.
- The inflator module connector terminals are damaged.

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

CAUTION: Refer to SIR Inflator Module Disposal Caution in Service Precautions.

Tools Required
- J 38826 SIR Deployment Harness
- J 39401-B SIR Deployment Fixture
- J 38826-25 Roof rail module adapter
- J 38826-75 Steering wheel module adapter (dual stage air bags)
- J 38826-80 I/P module adapter (dual stage air bags)

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




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. 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 the steering wheel module, place the steering wheel module in the center of the space.

IMPORTANT: Dual stage deployments are only used in steering wheel and instrument panel (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.




9. When deploying the I/P module, refer to the following instructions:
1. Place J 39401-B (2) in the center of the cleared area.
2. Fill the deployment fixture with water or sand.
3. Using the proper nuts and bolts, mount the I/P module (1) to the deployment fixture (2), with the vinyl trim facing up.
4. Securely tighten all fasteners that hold the I/P module (1) to the deployment fixture (2) prior to deployment.




10. If you have a roof rail module, refer to the following instructions:
- Place the SIR deployment fixture (3) in the center of the cleared area.
- Fill the deployment fixture with water or sand.
- Using the proper nuts (2) and mount the roof rail module (1) to the deployment fixture (3), with the vinyl face up.
- Adjust and secure the fixture arms (4) to the deployment fixture (3).
- Securely tighten all fasteners that hold the side impact module (1) to the deployment fixture (3) prior to deployment.




11. Inspect 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).

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




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).
16. Clear the area of people.

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.




17. Place a 12 volt minimum/2 amp minimum power source, such as a vehicle battery, near the shorted end of the SIR deployment harness.
18. Separate the 2 banana plugs on 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.




21. Seat one 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.

CAUTION: Refer to SIR Deployed Inflator Modules Are Hot Caution in Service Precautions.

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.
