The airbag warning light has been going off and on for some time now, mostly it stays on. I took it to dealer about a year ago, and they said it was a connection under the seat if I recall correctly. Does anyone know the fix for this. Do you have to disconnect battery first, and is there a danger of setting off airbag accidentally? Thankshttp://www.tahoeforum.com/images/smilies/smile.gif

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. Most systems can only be diagnosed using a scanner designed for the airbag system, however some use flash codes to indicate the problem. The scanners at Auto Zone or the ones that sell for @ $50 will not access the airbag system, only the engine systems (check engine light).
This website gives you the procedure for diagnosing and resetting some systems without a scanner. Some vehicle manufacturers accommodate that (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) and some require a scan tool. http://www.airbagsolutions.com/

no danger of setting off airbag if messing with connector under seat. assuming there is a break/open in wire(s), the system will NOT activate. it will not activate either if just removing seat and all connections are fine and light is off. if you want to remove negative battery cable for comfort, won't hurt as long as you can unlock the radio if equipped. the connector under the seat and for seatbelt latch is to see where seat is at, and if seat belt is fastened. if you have power seats, move seat forward, remove rear trim that covers the 2 bolts on rails, remove bolts. move seat all the way back and repeat for trim and bolts.(you may be able to repair wire without removing seat if you can see where break is at.) move seat forward, and unplug the big connector, and unplug the other yellow connector. Do all of this with the KEY OFF! remove seat from truck and inspect the wires and connectors. repair the breaks, keep in mind not to add/remove a large amount of wiring when doing this as system operation can be affected. re-intstall in reverse, making sure to tighten seat bolts to correct specs. let us know what you find. also, this is only a good idea if you know for sure that the problem is in the driver seat area.
