Air bag light?

Ok so i'm new to this site, and a proud Toyota owner!! I have a 1998 Tacoma and just recently the air bag light has been turning on, it only has done it a couple of times but when its on it drives me crazy!! I looked in my manual and all it said was to go to my Toyota dealer immediatly, so i did and they said they haven't heard of it, and wanted to do a diagnostic.s test for $90. so instead of paying the $90 i went to the local Checker's and used there diagnostic thing and it showed nothing was wrong. So does anyone have any idea what could be wrong, or how to fix it? thanks

 

It's most likely a bad seat belt tensioner. It cost me about $400 about a year ago to get it fixed because I was out of warranty.

 

Do a good search on google to see if there's a way you can do a diagnostic w/o taking it the the dealer. My light came on too and I did this trick where you connect the CG and TC terminals on your OBD port and a code flashes on the airbag light. Then you translate that code to a trouble shoot code and you know what's wrong. I know it works on the 2nd Gen. Im not sure about the first. For me it turned out to be the "clockspring" and I'm getting it replaced tomorrow.

 

Alright thanks guys i'll see what i can do, thanks again for the info.
