Deployment Outside Vehicle - Steering Wheel Module and I/P Module

Tools Required

• J 38826  SIR Deployment Harness. See Special Tools and Equipment .
• J 39401-B  SIR Deployment Fixture. See Special Tools and Equipment .
• An appropriate pigtail adaptor

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:

• Using the SIR diagnostics, it is determined 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.

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 .
CAUTION: Refer to SIR Inflator Module Handling and Storage Caution in Cautions and Notices.

6. Clear a space 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 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.

9. When deploying the I/P module, refer to the following instructions:
   1. Place the J 39401-B  (2) in the center of the cleared area. See Special Tools and Equipment .
   2. Fill the deployment fixture with water or sand.
   3. Mount the I/P module (1) in the deployment fixture (2) with the vinyl/plastic trim cover facing up.
   4. To mount, use 4 M 6 bolts (6), nuts (8), and washers (7) in order to properly secure the I/P module (1) to the J 39401-B  . See Special Tools and Equipment .
   5. Tighten all fasteners prior to deployment.

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

IMPORTANT: When deploying an inflator module the rapid expansion of gas involved with deploying an inflator module is very loud. Notify all the people in the immediate area that an inflator module will be deployed. When the inflator module deploys, the deployment fixture may jump about 30 cm (1 ft) vertically. This is a normal reaction of a deploying inflator module.
14. Connect the inflator module (1) to the adapter (2) on the J 38826  (3). See Special Tools and Equipment .
15. Clear the area of people.

16. Place a 12 volt minimum A minimum power source, i.e. vehicle battery, near the shorted end of the J 38826  . See Special Tools and Equipment .
17. Separate the banana plugs on the J 38826  . See Special Tools and Equipment .

IMPORTANT: The inflator module will deploy when the SIR deployment harness wires contact the power source.
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 Cautions and Notices.
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.
