Auto Airbag System Repair: service air bag light


Question
I have noticed "Service air bag light" is on when I start my truck unless the outside temperature is above 60 degrees.  Is that a sensor error?  Is this something that can be fixed without taking it to a dealer or mechanic?  Thank you for your time and attention.

Hi Jennifer:

Sorry about your truck.  without knowing the year make & moel of your truck, it's hard for me to give you specific advice.
On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly.  If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously.  If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system.  When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.   This website gives you the procedure for diagnosing and resetting airbag lights on the ...scanlist.aspx page listed below.    

The flashing light on your car is telling there is a problem.  On some vehicles, the light is flashing a two digit code.   Your vehicle MAY require a scan tool for the proper diagnosis.  Here's a site that will explain everything you need to know about airbag lights and resetting the system.   Once you know the code, you can most likely repair it yourself.  There are fairly easy procedures that most people are capable of repairing.  
Airbagsolutions.com has the fault code charts to tell you what is wrong!  Although it’s a pay site to access the code information($14.95/day), it’s a lot cheaper than going to the dealer.  You don;t need to buy anything to understand the details of your vehicle, only to access the code information specifically.

Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) .  Most all other vehicles require a scan tool for the diagnosis.  Here is a link to the list of vehicle and scanner requirements.
