CAUTION: When you are carrying an undeployed seat belt pretensioner:

Live (Undeployed) Seat Belt Pretensioner

Take special care when handling or storing a live (undeployed) seat belt pretensioner. A seat belt pretensioner produces rapid gas generation. This may cause the seat belt pretensioner, or an object in front of the seat belt pretensioner, to jettison through the air in the event of an unlikely deployment.

Shipping Procedures

Refer to the latest service bulletins for proper shipping procedures.

Scrapping Procedure

During the course of a vehicle's useful life, certain situations may arise which will necessitate the disposal of a live (undeployed) pretensioner. The following information covers the proper procedures for the disposing of a live pretensioner. Deploy the pretensioner before disposal. Do not dispose of a live pretensioner through normal disposal channels.

CAUTION: In order to prevent accidental deployment of the pretensioner which could cause personal injury, do not dispose of an undeployed pretensioner as normal shop waste. The undeployed pretensioner contains substances that could cause severe illness or personal injury if the sealed container is damaged during disposal. Use the following deployment procedures to safely dispose of an undeployed pretensioner. Failure to dispose of a pretensioner as instructed may be a violation of federal, state, or local laws.

Do not deploy a seat belt pretensioner in the following situations:

Deployment Procedures

The seat pretensioner 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:

Tools Required

CAUTION: In order to prevent accidental deployment of the pretensioner which could cause personal injury, do not dispose of an undeployed pretensioner as normal shop waste. The undeployed pretensioner contains substances that could cause severe illness or personal injury if the sealed container is damaged during disposal. Use the following deployment procedures to safely dispose of an undeployed pretensioner. Failure to dispose of a pretensioner as instructed may be a violation of federal, state, or local laws.

CAUTION: When you are deploying a pretensioner for disposal, perform the deployment procedures in the order listed. Failure to follow the procedures in the order listed may result in personal injury.

Deploy the seat belt pretensioners 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 seat belt pretensioner is subject to any required retention period.

1. Turn OFF the ignition.
2. Remove the ignition key.
3. Put on safety glasses.
4. Inspect the J 38826 SIR Deployment Harness and the appropriate pigtail adaptor for damage. Replace as needed.
5. Short the two SIR deployment harness (1) leads together using one banana plug seated into the other.
6. Connect the appropriate pigtail adaptor (2) to the SIR deployment harness (1).

CAUTION: When you are carrying an undeployed seat belt pretensioner:

•	Do not carry the seat belt pretensioner by the wires or connector on the pretensioner.

•	Do not touch the seat belt pretensioner in the area of the cable (1).

•	Do not cover the tube opening with your hand.

•	Keep the open end of the tube pointed away from you. Do not point the open end of the tube at another person.

•	When the pretensioner deploys the cable retracts. This shortens the pretensioner between the buckle and the mounting bolt. Grasp the pretensioner by the piston tube (2).

Disregarding these precautions may result in personal injury or unnecessary SIR system repairs.



7. Remove the seat belt pretensioner from the vehicle. Refer to Seat Belt Buckle Pretensioner Replacement - Driver or Seat Belt Buckle Pretensioner Replacement - Passenger.



8. Clear a space around a bench vice about 1.85 M (6 ft) in diameter for deployment of the seat belt pretensioner. Use a space free of activity. Make sure you have sufficient ventilation.
9. Make sure no loose or flammable objects are in the area.



10. Clamp the pretensioner, near the attachment bolt hole, in the vice.



11. Extend the SIR deployment harness and adaptor to full length from the seat belt pretensioner.
12. Place a 12 V minimum/2 A minimum power source (i.e., vehicle battery) near the shorted end of the harness.



13. Connect the seat belt pretensioner (1) to the adaptor (2) on the SIR deployment harness (3).
14. Firmly seat the adaptor into the seat belt pretensioner connector.
15. Clear the area of people.




CAUTION: When you are deploying a pretensioner for disposal, perform the deployment procedures in the order listed. Failure to follow the procedures in the order listed may result in personal injury.

16. Separate the two banana plugs on the SIR deployment harness.




Important: The rapid gas expansion involved with deploying a seat pretensioner is very loud. Notify all the people in the immediate area that you intend to deploy the seat belt pretensioner.

17. Connect the SIR deployment harness wires to the power source.



18. Disconnect the SIR deployment harness from the power source after the seat belt pretensioner deploys.
19. Seat one banana plug into the other in order to short the deployment harness leads.
20. If the seat belt pretensioner did not deploy, disconnect the adaptor and discontinue the procedure. Contact the Technical Assistance Group. Otherwise, proceed to the following steps.
21. Put on a pair of shop gloves.
22. Disconnect the pigtail adaptor from the seat belt pretensioner as soon as possible.
23. Inspect the pigtail adaptor and the SIR deployment harness. Replace as needed.
24. Dispose of the deployed seat belt pretensioner through normal refuse channels.
25. Wash hands with a mild soap.
