Air Bag
also know as SIR (Supplemental Restraint System) is a safety system
installed on most newer vehicles that works in conjunction with the seat
belt system in reducing fatalities in a head-on impact.
If the Air Bag lamp is on the system is disabled and will not function
or deploy in a head-on collision. Most vehicles will initiate a
bulb check when the ignition is first turned on. Normally the bulb
will come on for several seconds, possible flash and turn off if all
systems are working properly. Causes for the illuminated can be
many. A bad sensor, clock spring, deployed seatbelt and even an
alternator charging system not working properly may be the cause.
The
only way to check the system is to connect a scan tool (usually OEM (Original
Equipment Manufacture)) to check for codes and diagnose the system.
We have the OEM scan tools for: GM, Ford/Lincoln/Mercury,
Chrysler/Dodge/Plymouth, Acura/Honda, Toyota/Lexus and Audi/VW.
Also there is a good chance one of our aftermarket scan tools will be
able to read Air Bag codes for the other vehicles not listed.
