Live (Undeployed) Inflatable Restraint Steering Wheel Inflator Module


Object Number: 9039  Size: SH

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.

Take special care when handling and storing a live (undeployed) inflator module. Air bag deployment produces rapid gas generation. This may cause the inflator module, or an object in front of the inflator module, to jettison through the air in the unlikely event of an accidental deployment.

Shipping Procedures For Live (Undeployed) Inflatable Restraint Steering Wheel Inflator Modules

Service personnel should refer to the latest Service Bulletins for proper SIR inflator module shipping procedures.

Inflatable Restraint Steering Wheel Inflator Module Scrapping Procedure

During the course of a vehicle's useful life, certain situations may arise which will necessitate the disposal of a live (undeployed) inflator module. This information covers proper procedures for disposing of live a inflator module.

Caution: In order to prevent accidental deployment of the air bag which could cause personal injury, do not dispose of an undeployed inflator module as normal shop waste. The undeployed inflator module 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 inflator module. Failure to dispose of an inflator module as instructed may be a violation of federal, state, province, or local laws.

Before you dispose of a live inflator module, you must deploy the inflator module. Do not dispose of live inflator modules through normal refuse channels.

Do not deploy the air bag(s) in the following situations:

    • If you replace an inflator module under warranty. You may need to return the inflator module, undeployed, to Delphi Interior & Lighting Group. Refer to the latest service bulletin regarding SIR shipping procedures.
    • If a vehicle is the subject of a Product Liability Report related to the SIR system and is subject to a Preliminary Investigation (GM-1241). Do not alter the SIR system in any manner. Refer to the latest service bulletin on SIR shipping procedures.
    • If a vehicle is involved in a campaign affecting the inflatable restraint steering wheel inflator modules. Follow the use instructions in the Campaign Service Bulletin for proper SIR handling and shipping procedures.

You can deploy an inflator module inside or outside of the vehicle. The method you use depends upon the final disposition of the vehicle. Read Deployment Outside Vehicle and Deployment Inside Vehicle to decide whether to deploy the inflator module inside or outside of the vehicle.

Deployment Outside of the Vehicle

Tools Required

J 38826

Deploy the inflatable restraint steering wheel inflator module outside of the vehicle when you intend to return the vehicle to service. Situations that require deploying the inflator module outside the vehicle include the following:

    • You determine the inflator module does not function correctly using the SIR Diagnostics.
    • The inflator module is cosmetically damaged such as a scratch or rip in the cover.
    • The inflator module pigtail (if equipped) is damaged.
    • The inflator module connector is damaged.
    • An inflator module connector terminal is damaged.

Deployment and disposal of a malfunctioning inflator module is subject to any required retention period.

You must follow these inflator module deployment procedures exactly. Always wear safety glasses during this deployment procedure. Do not remove your safety glasses until the deployed inflator module is scrapped or shipped.

Before performing the procedures you should be familiar with servicing the SIR system and with proper handling of the inflator module. Procedures should be read fully before they are performed. The following procedure requires use of J 38826 with appropriate pigtail adapter. Do not attempt this procedure without J 38826 , and the adapter.

    • 2 amps minimum
  35. Disconnect the SIR deployment harness from the power source.

  36. Object Number: 9581  Size: SH
  37. Short the SIR deployment harness leads together by fully seating one banana plug into the other.
  38. In the unlikely event that the inflator module did not deploy after following these procedures, proceed immediately with steps 33 through 36. If the inflator module did deploy, proceed with steps 28 through 32.

  39. Object Number: 9433  Size: SH
  40. Put on a pair of shop gloves to protect your hands from possible heat and irritation when handling the deployed inflator module.
  41. 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. Gloves and safety glasses are recommended, however, as a precaution. Gloves and safety glasses help to prevent possible irritation of the skin or eyes.

    CAUTION: After an air bag deploys, the metal surfaces of the inflator module are very hot. To help avoid a fire or personal injury:

       • Allow sufficient time for cooling before touching any metal surface of the inflator module.
       • Do not place the deployed inflator module near any flammable objects.

  42. The metal canister, and the area surrounding the deployed 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.
  43. Disconnect the pigtail adapter from the inflator module as soon after the deployment as possible. This will prevent the hot inflator module canister from damaging the pigtail adapter, or the SIR deployment harness. The pigtail adapter and the SIR deployment harness are reusable.
  44. Inspect the pigtail adapter, and the SIR deployment harness for damage after each use. Replace the pigtail adapter, or the SIR deployment harness, as necessary.
  45. Allow the deployed inflator module to cool for at least 10 minutes. Dispose of the deployed inflator module through the normal refuse channels.
  46. Wash your hands with a mild soap and water.
  47. Notice: Follow the remaining steps in the unlikely event that the inflator module does not deploy after you have completed the previous procedures.

  48. Make sure that you disconnected the SIR deployment harness from the power source. Make sure that you have shorted the two banana plugs together.
  49. Disconnect the pigtail adapter from the inflator module.

  50. Object Number: 9427  Size: SH

    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.

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

Deployment Inside the Vehicle (Vehicle Scrapping Procedure)

Tools Required

J 38826

Deploy the inflatable restraint steering wheel inflator module inside the vehicle when destroying the vehicle. Deploy the inflator module inside the vehicle when salvaging the vehicle for component parts. This includes, but is not limited to the following situations:

    • The vehicle completes 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. When servicing an SIR equipped vehicle, use only new SIR system components, except when obtaining remanufactured parts from an authorized General Motors dealer.

       Caution: In order to prevent accidental deployment of the air bag which could cause personal injury, do not dispose of an undeployed inflator module as normal shop waste.
