Air Bag Systems: Description and Operation

Fig. 1 Airbag Restraint System:

This airbag system has five major components, the airbag module, unique steering column, clockspring switch, front impact sensors and Airbag System Diagnostic Module (ASDM). If any of these parts should fail, they must be replaced, as they cannot be repaired.
The fasteners, screws and bolts used for airbag components have special coatings and are specifically designed for the airbag system. They must not be replaced with substitutes. If fastener replacement is required, use the correct fasteners provided in the service package.
