The airbag light on my 1999 F150 recently started to blink a code 27 when started. It is followed by the light being on constantly after the pattern is repeated. Also the passenger side switch does not react according to the manual. Any help is appreciated...

 

My '99 airbag light started coming on around the middle of December... it flashes the code 32. I had a mechanic look it up and it refers to a open cicuit on the driver's side bag.

Mine doesn't come on all the time... sometime I hit a good size bump and it comes on, other times I can just be going down the highway and it starts flashing... and sometimes it comes on when I start the truck... go figure.

 

 

I have also had the same problem with my 99 F150 flashing 27. Im still trying to figure out what the problem is.

 

I wanted to update everyone and let you know that I resolved the problem. The problem turned out to be a burned out light bulb. The bulb is the one that indicates the passenger side bag is off. The bulb is soldered in a circuit board with a few resistors and a magnetic reed switch. Ford dosen't sell the bulb by itself and wanted $70.00 for the assembly. I substituted the bulb with an LED and currrent limiting resistor in serious. Think I used a 1K resistor.
