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. Situations that require deployment outside of the vehicle include the following:

• Using the SIR diagnostics, you determine that the inflator module is malfunctioning.
• The inflator module is cosmetically damaged, scratched, or ripped.
• The inflator module pigtail 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.
WARNING: Refer to SIR Inflator Module Handling and Storage Warning .
2. Remove the inflator module.

3. 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. Ensure you have sufficient ventilation.
4. Clear the area of loose or flammable objects.
NOTE: 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 dual stage module is required, both deployment loops must be energized to deploy the air bag.
5. If you are deploying a steering wheel inflator module, place the inflator module in the center of the space with the vinyl trim cover facing up and away from the surface.

6. When deploying an I/P inflator module, perform the following instructions:
   1. Place the EL-39401-B:  fixture 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).

7. When deploying a roof rail module, perform the following instructions:
   1. Place the EL-39401-B:  fixture (3) in the center of the cleared area.
   2. Fill the deployment fixture with water or sand to provide sufficient stabilization of fixture during deployment.
   3. Adjust and secure the fixture arms (4) to the deployment fixture (3), using the proper nuts and bolts.
   4. Attach the roof rail module in the deployment fixture and securely tighten all fasteners.

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