Deployment Inside Vehicle - Vehicle Scrapping Procedure

Deploy the seat belt pretensioners inside of the vehicle when destroying the vehicle or when salvaging the vehicle for parts. This includes but is not limited to the following situations:

• The vehicle has completed its useful life.
• Irreparable damage occurs to the vehicle in a non-deployment type accident.
• Irreparable damage occurs to the vehicle during a theft.
• The vehicle is being salvaged for parts to be used on a vehicle with a different VIN as opposed to rebuilding as the same VIN.

1. Turn OFF the ignition.
2. Remove the ignition key.
3. Put on safety glasses.
4. Remove all loose objects from the front seats.

8. Cut two 6.1 m (20 ft) deployment wires from a 0.8 mm (18 gage) or thicker multi-strand wire. These wires will be used for the seat belt pretensioner deployment harness.
9. Strip 13 mm (0.5 in) of insulation from both ends of the wires cut in the previous step.
10. Twist together one end from each of the wires in order to short the wires. Deployment wires shall remain shorted, and not connected to a power source until you are ready to deploy the seat belt pretensioner.

31. Completely cover the windshield and the front door openings with a drop cloth.
32. Stretch out all of the deployment harness wires on the passenger side of the vehicle to their full length.
33. Deploy each deployment loop one at a time.
34. Place a power source, 12 V minimum/2 A minimum, such as a vehicle battery, near the shorted end of the harnesses.
35. Separate one set of wires and touch the wire ends to the power source in order to deploy the seat belt pretensioners.
36. Disconnect the deployment harness from the power source and twist the wire ends together.
37. Continue the same process with the remaining deployment harnesses that are available.

38. Stretch out all the deployment harness wires on the driver side of the vehicle to their full length.
39. Place a power source, 12 V minimum/2 A minimum, such as a vehicle battery, near the shorted end of harness.
40. Separate one set of wires and touch the wire ends to the power source in order to delay the seat belt pretensioner.
41. Remove the drop cloth from the vehicle.
42. Disconnect all harnesses from the vehicle.
43. Discard the harnesses.
44. Scrap the vehicle in the same manner as a non - SIR equipped vehicle.
