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: 

z

After replacement of an inflator module under warranty. The inflator module may need to be returned 
undeployed to the manufacturer.  

z

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.  

z

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 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: 

z

Using the SIR diagnostics, you determine that the inflator module is malfunctioning.  

z

The inflator module is cosmetically damaged (scratched or ripped).  

z

The inflator module pigtail, if equipped, is damaged.  

z

The inflator module connector is damaged.  

z

The inflator module connector terminals are damaged.  

Deployment and disposal of a malfunctioning inflator module is subject to any required retention period.

6. 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. Ensure you have sufficient ventilation.
