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
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.
Shipping Procedures
Refer to the latest service bulletins for proper SIR inflator module
shipping procedures.
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. 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 original manufacturer of inflator
module. 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.
Deploy the 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:
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.
• | Using the SIR diagnostics, you 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. |
• | The inflator module connector is damaged. |

Handling a Deployed 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 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 to prevent
possible irritation
of the skin or eyes.
Deployment Inside Vehicle (Vehicle Scrapping Procedure)
Deploy the inflator modules 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. |
