1. Airbag inflator
This is an important component in the airbag module, which also comprises the airbag itself. The role of the inflator is quite simple just as its name indicates. It helps in instant inflation of airbag in the module to restrain you from forceful ejection out of the car. It also performs the function of producing effect of inflation through the mixture of potassium nitrate and sodium azide to bring out a nitrogen gas. That is why when gas gains entry into the airbag, the inflation effect comes into play.



2. Diagnostic monitoring unit
This diagnostic monitoring unit usually runs a test on the airbag system anytime the car is being started. It checks for proper functioning of the airbag system in your car. If by any chance you purchase an accident vehicle or you have had accident with it in the past, you will need to engage an expert to help you reset the airbag system. If not, you will get pissed off at the constant warning from the diagnostic monitoring unit of a possible malfunctioning airbag.

3. Indicator lamp
This is that light that warns you about the airbag system. When the vehicle runs a diagnostic test, it is normal for this indicator lamp to illuminates briefly. But if the light stays on, it means there is problem with the airbag system in your car.



4. Connection coil
This coil is what connects the airbag system with the steering wheel. This is mostly for the side of the driver. In any case there is also airbag for the passenger at the front seat; there will be an existence of the connection coil in the dashboard, found above the glove compartment area.

5. Airbag
Airbag in itself is also a part of the air bag system. When there is a possible collision with a very hard object or another vehicle, it is this safety bag that would be deployed. It is mostly made from nylon fabric and coated with a heat shield to protect the materials from any form of scorching

6. Wiring harness
This is a clear representation of several wires that join all parts of the airbag system together. When there is a problem with any of the wires, it would adversely affect the overall effectiveness of the airbag system.

Getting curious about what real life deployment of this airbag system in the vehicle shouldn’t be an avenue for you to test drive at insane speed in order experience the inflation of the airbag for fun. It is pre-installed in your car for emergency situation such as preventing head injury from hard collision, by reducing it to the barest minimum.

Drive safely!
