Live (Undeployed) Inflator Module
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.
Use special care when handling and 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 unlikely event of an accidental deployment.
Shipping Procedures for Live (Undeployed) Inflator Modules
Service personnel should refer to the latest Service Bulletins for proper
SIR inflator module shipping procedures.
Scrapping Procedure
During the course of a vehicle's useful life, you may need to dispose
of a live (undeployed) inflator module. The following information covers the
proper procedures for disposing of a live inflator module. 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.
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:
• | If you replace an inflator module under warranty, you may need
to return the inflator module, undeployed, to Delphi Interior & Lighting
Systems. 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 inflator
modules, follow the instructions in the Campaign Service Bulletin for proper
SIR handling and shipping procedures. |
Deployment Procedures
The inflator module may 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 procedure will work
best in a given situation.
Deployment Outside of the Vehicle (Inflatable Restraint Steering Wheel
Module)
Tools Required
J 38826 SIR Deployment
Harness
When you intend to return the vehicle to service, deploy the inflator
modules outside of the vehicle. Consider the following examples:
• | Using the SIR Diagnostics, you determine that the inflator module
does not function correctly. |
• | The inflator module is cosmetically damaged, such as a scratch
or a 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 theses deployment procedures, ensure that you are familiar
with servicing the SIR system. You should also know how to handle the
inflator module properly. Carefully read the procedures before you begin.
These procedures require the use of the following tools:
• | The appropriate pigtail adapter |
Do not perform the procedure without the J 38826
and the adapter.
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.
Important: This information applies only to inflatable restraint steering wheel
modules. Refer to

the inflatable restraint steering wheel module, if applicable.
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.
- With the vinyl trim cover facing up and away from the surface, place
the inflatable restraint steering wheel module on a work bench or other surface.
- Place the inflatable restraint steering wheel module away from
all loose or flammable objects.
- Clear a space on the ground
about 1.85 m (6 ft) in diameter where you intend to deploy
the inflatable restraint steering wheel module. If possible, use a paved,
outdoor location free of activity. Otherwise, use a space free of activity
on the shop floor. Provide sufficient ventilation.
- Clear all loose or flammable objects from the deployment area.
- Place the inflatable restraint steering wheel module in the space
just cleared, with its vinyl trim cover facing up.
- Extend the SIR deployment
harness and the pigtail adapter to full length from the inflatable restraint
steering wheel module.
- 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 meets the following criteria:
Important: Firmly seat the pigtail adapter into the inflatable restraint steering
wheel module connector. If you do not do this, the inflator module may not
deploy.
- Connect the inflatable restraint steering wheel module to the pigtail
adapter on the SIR deployment harness.
• | The deployment harness shall remain shorted until you are ready
to deploy the air bag. |
• | Do not connect the SIR deployment harness to a power source until
you are ready to deploy the air bag. |
• | The inflator module will immediately deploy when you connect the
power source. |
- Clear the area of all people and loose or flammable objects.
- Place the inflatable restraint steering wheel module with the
vinyl trim cover facing up.
- Notify all people in the immediate area before you deploy the
inflatable restraint steering wheel module for the following reasons:
• | An inflatable restraint steering wheel module deployment is very
loud. |
• | The deployment may startle any uninformed people in the area. |
- Separate the 2 banana
plugs on the SIR deployment harness.
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.
Notice: When the air bag deploys, the inflatable restraint steering wheel module
may jump about 30 cm (1 ft) vertically. This is
a normal reaction of the inflatable restraint steering wheel module to the
force of the rapid gas expansion inside the air bag.
Notice: The rapid gas expansion involved with deploying an air
bag is very loud. Notify all people in the immediate area that you intend
to deploy the inflator module.
- Connect the SIR deployment harness wires to the power source.
This immediately deploys the inflatable restraint steering wheel module.
- Use a vehicle battery when available, but always use a power source
that complies to the following criteria:
- Disconnect the SIR deployment harness from the power source.
- Short the SIR deployment
harness leads together by fully seating 1 banana plug into the other.
- In the unlikely event that the inflatable restraint steering wheel
module did not deploy after following these procedures, proceed immediately
with Steps 33-36. If the inflatable restraint steering wheel module
did deploy, proceed with Steps 28-32.
- Put on a pair of shop
gloves in order to protect your hands from possible heat and irritation when
you handle the deployed inflatable restraint steering wheel module.
After the inflatable restraint steering wheel 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. Gloves
and safety glasses 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 inflatable restraint
steering wheel module are very hot. Do not touch the metal areas of the inflatable
restraint steering wheel module for about 10 minutes after deployment.
Use care if you must move the deployed inflatable restraint steering wheel
module. Always wear gloves and handle the inflatable restraint steering
wheel module by the air bag or by the vinyl trim.
- Disconnect the pigtail adapter from the inflatable restraint steering
wheel module as soon after the deployment as possible. This will prevent the
hot inflatable restraint steering wheel module canister from damaging
either the pigtail adapter or the SIR deployment harness. The pigtail
adapter and the SIR deployment harness are reusable.
- Inspect both the pigtail adapter and the SIR deployment harness
for damage after each use. Replace the pigtail adapter or the SIR deployment
harness, as necessary.
- Allow the deployed inflatable restraint steering wheel module
to cool for at least 10 minutes. Dispose of the deployed inflatable
restraint steering wheel module through the normal refuse channels.
- Wash your hands with a mild soap and water.
Notice: Follow the remaining steps in the unlikely event that the
inflatable restraint steering wheel module did not deploy after following
these procedures.
- Disconnect the SIR deployment harness from the power source. Confirm
that you have shorted the 2 banana plugs together.
- Disconnect the pigtail adapter from the inflatable restraint steering
wheel module.
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.
- Temporarily store the inflatable restraint steering wheel module with
the vinyl trim cover facing up.
- Call the Technical Assistance group for further assistance.
Deployment Outside of the Vehicle (Inflatable Restraint IP 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.
General Motors dealers should refer to the latest General Motors Service
Bulletins for live (undeployed) inflatable restraint IP module scrapping and
disposal procedures. All others should contact a local General Motors
dealership for live inflatable restraint IP module scrapping and disposal
procedures. Dispose of deployed inflatable restraint IP modules through
normal refuse channels.
Deployment Inside Vehicle (Vehicle Scrapping Procedure)
