OT Service Air Bag?

geok · Sep 20, 2009

03 Chevy Suburban 4X4 that wife and I travel to farm shows etc. has been displaying service air bag warning in place of odometer reading lately. Just does it now and then but it is annoying. How do you service air bag? I just know I won't be touching them.
Thank you for any information.

If the air bag light is staying on, then most likely there is a trouble code stored in the control module. You need a good scan tool to read the trouble codes. Then there are diagnostic trees to follow to find the problem.
Hope this helps,

Lots of possibilities...looking around the net,it seems to be a fairly common,full size GM issue,of various causes...however there is some indication dealers have a TSB(Technical Service Bulletin)regarding these problems.Some causes were moisture or corrosion in bumper sensors,tension on underseat wiring(moving seat cleared it up),in steering column connection fault,defective sensor,defective module etc,etc.
-Shame that such gov't mandated"features" are not required to be lifetime warranteed,like emissions components in some states.-

Best to let a dealership check it out. You mess with the wrong thing and the bag goes off, it gets spendy real fast. There's sensors in the front, knee area, control module, steering wheel clock spring, etc. Any of those could be going bad or have a bad connection.

Like others have said take it to the dealer. I was thinking just the other day about air bags going off. what if someone was pulling your car with a air bag, and using a chain, and give the car a sudden jerk with a chain will it set off the bag? Stan

Stan, I'm pretty sure you would snap the chain or break something before the air bag would go off in either vehicle. I think it takes around 60 G's to set off most air bags; for a 4000 lb vehicle that's 240,000 pounds of force.

Take it to a dealer who has someone qualified to service the bags. Don't mess with it yourself.

If anyone dies because an airbag didn't deploy, whoever had his fingers on it last might as well buy a plane ticket to South America.

My 07 Silverado Classic does that, but it's been a while. The first time it did was right after I tossed the 3/4 ratchet in on the passenger floor.
