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 inflator module
deployment produces a rapid generation of gas. This may
cause the inflator module, or an object in front of the inflator
module, to project through the air in the event of an unlikely
deployment.
Scrapping Procedure
During the course of a vehicle's useful life, certain situations may
arise which will require the disposal of a live (undeployed) inflator module.
Do not dispose of a live (undeployed) inflator module through
normal disposal channels until the inflator module has been
deployed. The following information covers the proper procedures
for the disposing of a live (undeployed) inflator module.
Do not deploy the inflator module in the following situations:
• | After replacement of an inflator module under warranty. The inflator
module may need to be returned undeployed to the manufacturer. |
• | If the vehicle is the subject of a product liability report (GM-1241)
related to the SIR system. When a vehicle is the subject of a product liability
report, do not alter the SIR system in any manner. |
• | If the vehicle is involved in a campaign affecting the inflator
modules. Follow the instructions in the campaign service bulletin for proper
SIR handling 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 (Steering Wheel Module and IP Module)
Deploy the 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:
• | Using the SIR diagnostics, you determine that the inflator module
is malfunctioning. |
• | The inflator module is cosmetically damaged (scratched or ripped). |
• | The inflator module pigtail (if equipped) is damaged. |
• | The inflator module connector is damaged. |
• | The inflator module connector terminals are damaged. |
Deployment and disposal of a malfunctioning inflator module is subject
to any required retention period.
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.
Tools Required
• | An appropriate pigtail adaptor |
- Turn OFF the ignition.
- Remove the ignition key.

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.
- Place the inflator module
with the vinyl trim cover facing up and away from the surface on a work bench.
- Clear a space on the ground
about 1.85 m (6 ft) in diameter for deployment of the inflator
module. If possible, use a paved, outdoor location free of
activity. Otherwise, use a space free of activity on the
shop floor. Make sure you have sufficient ventilation.
- Make sure no loose or flammable objects are in the area.
- When deploying the steering wheel module, place the steering wheel
module in the center of the space.
- When deploying the IP
module, refer to the following instructions:
• | Place the J 39401-B
SIR deployment fixture (2) in the center of the cleared area. |
• | Fill the deployment fixture with water or sand. |
• | Mount the IP module (1) in the deployment fixture (2) with the
vinyl/plastic trim facing up. |
• | To mount, use four M 6 bolts (6), nuts (8), and washers
(7) in order to properly secure the IP module (1) to the deployment fixture
(2). |
• | Securely tighten all fasteners prior to deployment. |
- Inspect the J 38826
SIR deployment harness and the appropriate
pigtail adapter for damage. Replace as needed.
- Short the two SIR deployment harness (1) leads together using
one banana plug seated into the other.
- Connect the appropriate pigtail adapter (2) to the SIR deployment
harness (1).
- Extend the SIR deployment
harness and adapter to full length from the deployment fixture.
- Connect the inflator module
(1) to the adapter (2) on the SIR deployment harness (3).
- Clear the area of people.
Important: When deploying an inflator module, the rapid expansion of gas is very
loud. Notify all the people in the immediate area that an inflator module
will be deployed.
Important: When the inflator module deploys, the deployment fixture may jump about
30 cm (1 ft) vertically. This is a normal reaction of deploying
an inflator module.
- Place a 12 V minimum/2 A
minimum power source (i.e. vehicle battery) near the shorted end of the SIR
deployment harness.
- Separate the two banana plugs on the SIR deployment harness.
- Connect the SIR deployment
harness wires to the power source. Inflator module deployment will occur when
contact is made.
- Disconnect the SIR deployment harness from the power source.
- Seat one banana plug into
the other in order to short the deployment harness leads.
- If the inflator module did not deploy, disconnect the adapter
and discontinue the procedure. Contact the Technical Assistance Group. Otherwise,
proceed to the following steps.
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.
|
- Put on a pair of shop gloves.
