Usually made up of nylon fabric, the airbags are coated with a heat shield and are assembled behind the steering wheel centre boss, passenger side of the dashboard and internal side pillars.
2. Wiring harness  All the components of the airbag system are interconnected to each other with the help of a number of wires. If any one of the wire gets damaged, the entire functioning of the airbag system gets affected, or in the worst case, the airbags might not open up at the time of the crash.

4. Airbag indicator light  This light is present in the instrument console of your car, and glows with yellow light. This lamp glows in two conditions  either there is some malfunction somewhere in the airbag system or for a few seconds when the vehicle diagnostic check takes place.

5. Diagnostic monitoring unit  This particular thing is responsible for carrying out a system check whenever you turn on your car. If there is any malfunction in the airbags system, or the airbags are not reinstalled properly after repairing caused by inflation of airbags at the time of the accident, it will turn on the airbag indicator light and warn you of a possible fault.
6. Airbag inflator  The airbag inflator is that component which opens up the airbags at the time of the crash. This particular system creates nitrogen gas and inserts it into the airbags for immediate inflation of the airbags, with the gas produced as a result of a mixture of potassium nitrate and sodium azide.
