I just traded for a 2008 f150 xlt. I didn't think much about it at the time I was only one in truck but noticed my passenger side airbag light was on which in normal cause no one was in the seat. Picked up my buddy for work when he set down it did not go off. Also the light on the cluster is on too. Any ideas what this might be.

 

As far as i know the 08 does not have a keyed on/off switch

 

when you first start the truck the air bag light should flash a certain amount of times. that is the trouble code. as an example 5 flashes, a pause, and 5 flashes again is the code for passenger side air bag light being burned out.

 

Don't think they flashed but when I get in Sunday I will check see if they will flash

 

Check for flash Key on, engine off

 

Ok thanks I'll post it asap Sunday

 

Ok tried this several times and air bag lights are just on no flash guess I need to check my fuse first if not that what else might it be. They don't flash at all

 

Probably going to need a scanner to read those codes.
I could do them in Md
John in Tenn

 

Yup, time to scan it.

 

All fuses are good so guess its time yto scan codes I'm in north east Mississippi corinth area

 

After a long diagnosis and many busted knuckles I got frustrated and gave up on my air bag lights and just decided to live with them staying on. Then yesterday my youngest got sick in my truck and my wife had to turn around putting her knees in the seat soon as she did that both lights went out and are not working as they should. Still not sure but think the sensor was stuck. Thanks for all the info and help

 

So far seems to be working as it should. Time will tell if I need to replace any individual components. Drove it around the yard today and went to town with no light coming on. Hope it was just a dirty sensor in the seat. I checked the on on the brace on the front of the truck and it looks like a new one has been put on recently.
