Caution: Refer to SIR Inflator Module Handling and Storage Caution in the Preface section.
Live (Undeployed) Inflator Modules
Use special care when handling or storing live (undeployed) inflator
modules. 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 Procedures
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 disposing of a live (undeployed) inflator
module.
Do not deploy an 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
Inflator modules 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-IP Module, Side Impact Module, and
Steering Wheel Module
Deploy inflator modules 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: Refer to SIR Inflator Module Disposal Caution in the Preface section.
Tools Required
| • | An appropriate pigtail adaptor |
- Turn OFF the ignition.
- Remove the ignition key.
- Put on safety glasses.
- Remove the inflator module. Refer to the following:
Caution: Refer to SIR Inflator Module Handling and Storage Caution in the Preface section.
- Place the inflator module
with the vinyl trim cover facing up and away from the surface on a work bench,
floor or deployment fixture.
- Clear an area on the floor
approximately 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 an area 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 a steering wheel module, place the steering wheel
module in the center of the cleared area.
- When deploying an IP module,
refer to the following instructions:
| • | Place the J 39401-B
(2) in the center of the cleared area. |
| • | Fill the deployment fixture (2) with water or sand. |
| • | Mount the IP module (1) in the deployment fixture (2)
with the vinyl/plastic trim facing up. |
| • | To mount, use 4 M 6 bolts (6), nuts (8), and washers (7)
to properly secure the IP module (1) to the deployment fixture (2). |
| • | Tighten all fasteners prior to deployment. |
- When deploying a side
impact module, refer to the following instructions:
| • | Place the J 39401-B
(3) in the center of the cleared area. |
| • | Fill the deployment fixture (3) with water or sand. |
| • | Mount the side impact module (1) in the deployment fixture (3)
with the vinyl/plastic trim facing up. |
| • | Adjust and secure the J 39401-B
arms (4) to the deployment fixture (3). |
| • | To mount, use 2 M 6 x 1.0 nuts (2) with washers to secure
the side impact module (1) to the deployment fixture arms (4). |
| • | Tighten all fasteners prior to deployment. |
- Inspect the J 38826
and the appropriate pigtail adapter
for damage. Replace as needed.
- Short the 2 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).
Important:
| • | The rapid expansion of gas involved with deploying an inflator module
is very loud. Notify all people in the immediate area that an inflator module
will be deployed. |
| • | When the inflator module deploys, the deployment fixture may jump vertically.
This is a normal reaction of the inflator module due to the force of the
rapid expansion of gas inside the inflator module. |
- Clear the area of people.
- Separate the 2 banana
plugs on the SIR deployment harness.
- Place a 12 V minimum/2 A
minimum power source, i.e. vehicle battery, near the shorted end of 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.
Caution: Refer to SIR Deployed Inflator Modules Are Hot Caution in the Preface section.
- Seat 1 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 for
further assistance. Otherwise, proceed to the following steps.
- Put on a pair of shop
gloves.
- Disconnect the pigtail adapter from the inflator module as soon
as possible.
- Dispose of the deployed inflator module through normal refuse
channels.
- Wash hands with a mild soap.
Deployment Inside Vehicle-Vehicle Scrapping Procedures
Deploy 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. |
