- Turn the ignition switch to the OFF position.
- Remove the ignition key.
- Put on safety glasses.
- Remove the seat belt pretensioner from the vehicle.
- When carrying a pretensioner to the deployment area keep the open end of pretensioner pointed away from the body.
- Clear a space on the ground about 1.85 M (6 ft) in diameter for deployment of the pretensioner. 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.
- Make sure no loose or flammable objects are in the area.
- Place the EL-39401-B SIR deployment fixture in the center of the cleared area.
- Fill the fixture plastic reservoir with water or sand.
- Mount the pretensioner (1) in the SIR deployment fixture (3) with the open end facing up using the following mounting method. 10.1. Adjust and secure the EL-39401-B arms (4) to the deployment fixture (3). 10.2. To mount, use the proper size bolt (2) and nut (5) with washers in order to secure the pretensioner (1) to the deployment fixture brackets (4). 10.3. Securely tighten all fasteners prior to deployment.
- Inspect the EL-38826 SIR Deployment Harness and the appropriate pigtail adapter for damage. Replace if necessary.
- Short the 2 SIR deployment harness (1) leads together using one banana plug seated into the other.
- Connect the appropriate pigtail adapter (2) to the SIR deployment harness (1).
- Extend the SIR deployment harness and adapter to full length from the deployment fixture.
- Connect the pretensioner (1) to the adapter (2) on the deployment harness (3).
- NOTE: The rapid gas expansion involved with deploying a pretensioner is very loud. Notify all the people in the immediate area that you intend to deploy the seat belt pretensioner. Clear the area of people.
- WARNING: 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. Separate the 2 banana plugs on the SIR deployment harness.
- NOTE: When the seat belt pretensioner deploys, the deployment fixture may jump about 30 cm (1 ft) vertically. This is a normal reaction of the seat belt pretensioner due to the force of the rapid expansion of gas inside the pretensioner. Place a 12 V minimum/2 A minimum power source (i.e., vehicle battery) near the shorted end of the harness.
- Connect the SIR deployment harness wires to the power source. Pretensioner deployment will occur when contact is made.
- Disconnect the SIR deployment harness from the power source after the pretensioner deploys.
- Seat one banana plug into the other in order to short the deployment harness leads.
- If the pretensioner did not deploy, disconnect the adapter and discontinue the procedure. Contact the Technical Assistance Group. Otherwise, proceed to the following steps.
- Put on a pair of shop gloves.
- Disconnect the pigtail adapter from the pretensioner as soon as possible.
- Check the pigtail adapter and SIR deployment harness. Replace if necessary.
- Dispose of the deployed pretensioner through normal refuse channels.
- Wash hands with a mild soap.
