Great Article! A faulty clock spring is common and many people take it as more of an announce than anything else. Yes the Airbag might function with it, but its not always the case. Airbags save lives and we need to get these fixed asap. There are many other reasons why the airbag light, also called the 'SRS' light in some cars might come on. In some cars, it might be a sign that the airbags have been deactivated. This is very dangerous and you need to get this check soon. It is also possible that the airbag sensors are not working. Faulty sensors can cause the light to go off and if they are in a bad shape, the airbags might not deploy when needed - so we need to get this checked. Another common reason is when your car was in a small accident but the force was not enough for the airbags to deploy. This might confuse the car's system and you might have to reset the whole thing. So while this article does help a lot, you also need to keep your eyes open for other problems.
