Deployment Outside Vehicle-Steering Wheel Module, IP Module, and Side Impact 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

1. Deployment and disposal of a malfunctioning inflator module is not subject to any required retention period. 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 situations:
   • Using the SIR diagnostics, you determine that the inflator module is malfunctioning.
   • The inflator module is cosmetically damaged, i.e., scratched or ripped.
   • The inflator module pigtail, if equipped, is damaged.
   • The inflator module connector is damaged.
   • The inflator module connector terminals are damaged.
   CAUTION: Refer to SIR Inflator Module Disposal Caution in Cautions and Notices.
CAUTION: Refer to SIR Inflator Module Handling and Storage Caution in Cautions and Notices.
2. Before you begin to remove the inflator module, turn OFF the ignition.
3. Remove the ignition key.
4. Put on safety glasses.
5. Remove the inflator module. Refer to the following procedures:
   • 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-left, refer to Inflatable Restraint Side Impact Module Replacement - Front .

7. 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.
IMPORTANT: Dual stage deployments are only used in the steering wheel and IP inflator modules, if the vehicle is equipped. 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 inflator module.
8. Make sure that loose or flammable objects are not in the area.
9. If you are deploying a steering wheel module, place the steering wheel module in the center of the space.

10. When deploying an IP module, refer to the following instructions:
    • Place the J 39401-B  SIR deployment fixture (2) in the center of the cleared area. See Special Tools and Equipment .
    • Fill the deployment fixture with water or sand.
    • Mount the IP 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.

11. When deploying the side impact module-left, refer to the following instructions:
    • Place the J 39401-B  SIR deployment fixture (3) in the center of the cleared area. See Special Tools and Equipment .
    • Fill the deployment fixture with water or sand.
    • Mount the side impact module-left (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). See Special Tools and Equipment .
    • To mount, use 2 m 6 x 1.0 nuts (2) with washers in order to secure the side impact module-left (1) to the deployment fixture arms (4).
    • Securely tighten all fasteners prior to deployment.

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