Inside of Vehicle (Vehicle Scrapping Procedure)

Deploy the inflator modules inside the vehicle when destroying the vehicle. Deploy the inflator modules inside the vehicle when salvaging the vehicle for component 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 theft.
^ You are salvaging the vehicle for component parts to use on a vehicle with a different Vehicle Identification Number (VIN) as opposed to rebuilding as the same VIN. Never use SIR components from another vehicle. This ensures SIR system integrity. Always use new SIR system components, except when obtaining remanufactured parts from an authorized General Motors dealer.

CAUTION: When you are deploying an Inflator module for disposal, perform the deployment procedures in the order listed:
^ Wear safety glasses throughout the procedures.
^ Make sure the area around the inflator module is clear of all people and loose or flammable objects.
^ Short the deployment harness wires as instructed.
^ Connect the deployment harness to the inflator module before you connect it to the power source.
^ Connect the deployment harness to the power source to immediately deploy the air bag.
Failure to follow the procedures in the order listed may result in personal injury.

1. Turn the ignition switch to the LOCK position.
2. Remove the key.
3. Put on safety glasses.
4. Remove all loose objects from the front seats.
5. Disconnect the inflatable restraint steering wheel module, yellow 2-way connector. This connector is located near the base of the steering column.
6. Cut the inflatable restraint steering wheel module yellow 2-way harness connector from the vehicle. Leave at least 160 mm (6 inches) of wire at the connector (Figure 23).
7. Strip 13 mm (0.5 inches) of insulation from each wire lead of the connector (Figure 23).
8. Cut two 4.6 m (15 feet) deployment wires from 0.8 mm2 (18 gauge) or thicker multi-strand wire. Use these wires to fabricate the driver deployment harness.
9. Strip 13 mm (0.5 inches) of insulation from both ends of the wires cut in the previous step.

CAUTION: When you are deploying an Inflator module for disposal, perform the deployment procedures in the order listed:
^ Wear safety glasses throughout the procedures.
^ Make sure the area around the inflator module is clear of all people and loose or flammable objects.
^ Short the deployment harness wires as instructed.
^ Connect the deployment harness to the Inflator module before you connect it to the power source.
^ Connect the deployment harness to the power source to immediately deploy the air bag.
Failure to follow the procedures in the order listed may result in personal injury.

10. Short the wires by twisting together one end from each (Figure 24). Deployment wires shall remain shorted, and not connected to a power source until you are ready to deploy the air bag.
11. Twist together one connector wire lead to one deployment wire (1). The connection must be mechanically secure (Figure 25).

12. Bend flat the twisted connection that you made in the previous step (2). Secure the connection by wrapping tightly with electrical tape. This will also insulate the connection (Figure 25).
13. Twist together, bend and tape the remaining connector wire lead (3) to the remaining deployment wire (Figure 25).
14. Connect the deployment harness to the inflatable restraint steering wheel module, yellow 2-way connector at the base of the steering column.
15. Route deployment harness out the driver side of the vehicle (Figure 26).
16. Disconnect inflatable restraint I/P module, yellow 2-way connector. This connector is located above the RH sound insulator.
17. Cut the inflatable restraint I/P module harness connector from the vehicle. Leave at least 160 mm (6 inches) of wire at the connector (Figure 27).
18. Strip 13 mm (0.5 inches) of insulation from each wire lead of the connector (Figure 27).
19. Cut two 6.1 m (20 feet) deployment wires from 0.8 mm2 (18 gauge) or thicker multi-strand wire. Use these wires to fabricate the passenger deployment harness.
20. Strip 13 mm (0.5 inches) of insulation from both ends of the wires cut in the previous step.
21. Short the wires by twisting together one end of each (Figure 28). The deployment wires shall remain shorted and not connected to a power source until you are ready to deployed the air bag.

22. Twist together one connector wire lead to one deployment wire (1). The connection must be mechanically secure (Figure 29).
23. Bend flat the twisted connection that you made in the previous step (2). Secure the connection by wrapping tightly with electrical tape. This will also insulate the connection (Figure 29).
24. Twist together, bend and tape the remaining connector wire lead (3) to the remaining deployment wire (Figure 29).
25. Connect the deployment harness to the inflatable restraint I/P module, yellow 2-way connector.
26. Route deployment harness out the passenger side of the vehicle (Figure 30).
27. Be sure to clear the inside of the vehicle and the area surrounding the vehicle of any people. Clear the vehicle of all loose or flammable objects.
28. Stretch the driver and passenger deployment harnesses to their full length (Figures 26 and 30).
29. Completely cover windshield area and front door window openings with a drop cloth, blanket or similar item. This reduces the possibility of injury due to possible fragmentation of the vehicle's glass or interior.
30. Notify everyone in the immediate area that you intend to deploy the air bags. The deployment will be very loud. This may startle any uninformed people in the area.
31. Place a power source near the shorted end of the SIR deployment harness. Use a vehicle battery when available, but always use a power source that complies to the following:
^ 12 volts minimum.
^ 2 amps minimum.
32. Separate the two ends of the driver deployment harness wires (Figure 31).

Failure to follow the procedures in the order listed may result in personal injury.

NOTICE: The rapid gas expansion involved with deploying an air bag will be very loud. Notify all people in the immediate area that you intend to deploy the inflator modules.

33. Connect the SIR deployment harness wires to the power source to immediately deploy the inflatable restraint steering wheel module (Figure 31).
34. Disconnect the deployment harness wires from the power source.
35. Separate the two ends of the passenger deployment harness wires (Figure 32).
36. Connect the passenger deployment harness wires to a power source. This will immediately deploy the inflatable restraint I/P module (Figure 32).

Figure 32:

After the inflator module has deployed, the surface of the air bag may contain a powdery residue. This powder consists primarily of cornstarch (used to lubricate the bag as it inflates). and by-products of the chemical reaction. The deployment reaction produces sodium hydroxide dust (similar to lye soap). The sodium hydroxide quickly reacts with the atmospheric moisture. This atmospheric moisture converts the sodium hydroxide into sodium carbonate and sodium bicarbonate (baking soda). Therefore, you will probably find no sodium hydroxide present after the deployment. , As a precaution gloves and safety glasses are recommended. Gloves and safety glasses help to prevent possible irritation of the skin or eyes.

CAUTION: Immediately following the deployment of an air bag, the metal surfaces of the inflator module are very hot. Do not place the deployed inflator module near any flammable objects. Wait for about ten minutes before touching any metal surface of the inflator module. Disregarding these precautions may cause fire or personal injury.

The metal canister and the area surrounding the inflator module are very hot. Do not touch the metal areas of the inflator module for about ten minutes after deployment. If you must move the deployed inflator module, use caution. Always wear gloves and handle the inflator module by the air bag or the vinyl trim (Figure 22).

37. Disconnect the deployment harness wires from the power source.
38. Short the driver deployment harness wires by twisting together one end from each of the wires together. Repeat this procedure for the passenger deployment harness.
39. Carefully remove the drop cloth from the vehicle.
40. Disconnect the driver deployment harness and the passenger deployment harness from the vehicle.
41. Discard both deployment harnesses.
42. After deploying both air bags, you may scrap the vehicle in the same manner as a non-SIR equipped vehicle.
43. In the unlikely event that either or both of the inflator modules did not deploy after following these procedures, proceed immediately with Steps 44 through 46.
44. Remove the undeployed inflator module(s) from the vehicle. Service and Repair

CAUTION: When you are carrying an undeployed inflator module:
^ Do not carry the inflator module by the wires or connector on the inflator module.
^ Make sure the bag opening points away from you.
When you are storing an undeployed inflator module, make sure the bag opening points away from the surface on which the inflator module rests. When you are storing a steering column, do not rest the column with the bag opening facing down and the column vertical. Provide free space for the air bag to expand in case of an accidental deployment. Otherwise, personal injury may result.

45. Temporarily store the inflator module with its vinyl trim cover facing up.
46. Call the Technical Assistance group for further assistance.
