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.
Live (Undeployed) Inflator Module
Important: Dispose of deployed IP modules through normal refuge channels.
Take special care when handling or storing a live (undeployed) inflator
module. An 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 event of an unlikely deployment.
Scrapping Procedure
During the course of a vehicle's useful life, the disposal of a live
(undeployed) inflator module may become necessary. The following information
covers the proper procedures for the disposing of a live inflator
module. Deploy the inflator module before disposal. Do not
dispose of the module through normal disposal channels.
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.
Do not deploy an air bag in the following situations:
• | After replacement of an inflator module under warranty. The module
may need to be returned undeployed to the Delphi Interior & Lighting Group.
Refer to the latest service bulletin regarding SIR shipping
procedures. |
• | If the 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 the vehicle is involved in a campaign affecting the inflator
modules. Follow the instructions in the Campaign Service Bulletin for proper
SIR handling and shipping procedures. |
Deployment Procedures
The inflator module 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:
Deployment Outside Vehicle (Inflatable Restraint Steering Wheel Module)
Tools Required
• | An appropriate pigtail adapter |
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.
CAUTION: When you are deploying an inflator module 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 inflatable restraint steering wheel inflator
module outside of the vehicle when the vehicle will be returned to service.
Situations that require deployment outside of the vehicle include
the following items:
• | Use the SIR diagnostics in order to determine that the inflator
module does not function properly. |
• | The inflator module is scratched or ripped on the cover. |
• | The inflator module pigtail, if equipped is damaged. |

Handling a Deployed Inflatable Restraint Steering Wheel Inflator Module
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 the bag 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.
As a precaution, wear gloves and safety glasses in order to help
prevent possible irritation of the skin or eyes.
