Subject:
Section 9J - Revised Remove/Install Procedure for Inflatable Restraint
I/P Module
Models:
1997 Chevrolet and GMC C/K Models
This bulletin is being issued to revise the Remove/Install Procedure for the Inflatable Restraint I/P Module in Section 9J of the Service Manual.
Inflatable Restraint I/P Module
Live (undeployed) Inflator Module
Refer to Inflator Module Handling/Shipping/Scrapping in Section 9J of the Service Manual.
Deployed Inflator Module
After the inflator module has been 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. Sodium hydroxide dust (similar to lye soap) is produced as a
by-product of the deployment reaction. The sodium hydroxide then quickly reacts with atmospheric moisture and is converted to sodium carbonate and
sodium bicarbonate (baking soda). Therefore, it is unlikely that sodium hydroxide will be present after deployment. As with many service procedures,
you should wear gloves and safety glasses. (See Figure 1)
