2009 GMC Sierra GMT-900 Air Bag Schematic Wanted

[paradise710]

Anyone have an Air Bag wiring schematic for a 2009 GMC Sierra SLE Crew Cab? I have an intermittent air bag light that comes on only when the interior is warm to very hot. But goes out and back on again over rough terrain. Does not come on when the truck is cold and stays off until the cabin gets very warm. Anyone know of any recalls on this? Figured this wouldn't be warranty anymore, so I'm going to have to start tracing myself. Thanks!

get it scanned first ,the light means there is a code ,,,,,,let us know we will give you the diag tree for that code,

 

btw,some crappy code readers may not read SIR codes

I will see what I can do to get it scanned. The hard part is that the light is so intermittent. When I park in the driveway, the light goes out. So if I take it to a dealer, could they read to see if there were any past codes related to the air bag light? Thanks!

yes

i believe history codes stay,the road test will put the light on anyways

 

you may as well have them diagnose the code or completely repair it as well,

 

the code does not tell you what part to throw at the truck,there are several possiblities as to the fault
