In just a few cases, the crash sensors and air bag control modules have commanded deployment of the air bags, but the air bags failed to reply. The third motive is that there might be a defect that prevented the deployment signal from reaching the air bag modules and deploying them.

The fourth purpose is that there may very well be a defect that prevented the actual air bag modules from deploying accurately. This is sort of at all times due to defects inside the air bag modules themselves, normally as a result of poor high quality management.
