Handling Deployed Modules

Safe handling of steering wheel module requires adhering to following procedures for both live and deployed steering wheel modules.
Always wear safety glasses when servicing an inflatable restraint system vehicle and when handling a steering wheel module.
The following components cannot be repaired, as these components are serviced only by replacement.
1. Forward sensor
2. Arming sensor
3. Power supply
4. Diagnostic energy reserve module (DERM)
5. SIR control module
6. Coil assembly
7. Steering wheel module

After the inflator module has been deployed, the surface of the air bag may contain a powdery residue. This powder consists primarily of corn starch (used to lubricate the air bag as it inflates) and by-products of the chemical reaction. Sodium hydroxide dust (similar to lye dust) 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. Always wear safety glasses and gloves when handling a deployed module, and wash hands with mild soap and water afterward.
