In this video I show examples of the two absolute most common causes for an airbag light in the 2004-2008 model years and what to inspect before the airbag light comes on so your system is fully operational.

 

Thanks for the video. I just bought an '05 F-150 XLT 5.4L. The previous owner said the air bag light is on because the light bulb in the dash (above the cd player) burnt out. Which sounded like one of the common reasons you described. How do you fix that? From the blinking sequence, it looks like I have error code 5-2. Also, while the air bag light is on, does that mean my airbags won't deploy if I get in an accident? Thanks in advance.
