I have a 2008 and this morning it started just randomly making what sounds like a seat belt warning tone. It sounds off just once every so often with no lights coming on on the dash or anything like that. The airbag warning indicator comes on when I first start the truck. No idea what this noise is. Any thoughts????

 

What is the number of beeps and pattern? I know in my 99 5 beeps pause then repeat for a total of 25 is airbag light on dash burned out and/or airbag error.

 

yes it only does it one time and then after awhile it did another time. And I checked and the idiot light for the airbag goes come on when you turn the truck on
