The problem is that the air bag code 27 is on, a bulb is burned out @ air bag on/off switch. I needed to replace the on/off bulb for the air bag to deactivate the code.

Parts: 1) 12-volt colored lamp (Radio Shack part: 272-1099)

Tools: 1) socket set 2) Philips head screw driver 3) soldering iron

Replacing part Procedure: 1) remove ash tray from console panel 2) using a socket set, remove 4 hex head screws from console panel 3) pull console panel out of the two clips 4) remove connector from air bag key module in console panel and take console panel to a work bench 5) remove 2 Philips head screws to remove the airbag key module 6) carefully unclip the plastic tabs that hold the airbag key module case together 7) remove connector circuit board from air bag key module 8) solder the yellow replacement lamp to the two solder pads for the original lamp on the back side of the circuit board (which wire to which pad does not matter) 9) tie the replacement lamp in place next to the original lamp 10) replace the circuit board in the airbag key module and snap the case back together 11) connect the airbag key module in the truck and start the engine to check that the lamp illuminates and that the alarm does not sound 12) screw the airbag key module back into the console panel 13) snap the console panel back into the truck 14) replace the 4 hex head screws 15) replace the ash tray

Ford --Prior to 2005, most models utilized Flash Codes --the airbag light would flash a 2 digit code repeatedly before remaining lit continuously. (There are some Ford, Lincoln and Mercury models that DO NOT use flash codes at all). The airbag codes can be read by counting the flashes on the dash light (flash, flash, pause, flash, = a code 21 on the fault code chart). The system would clear itself once the fault was corrected. Subsequent to 2005, most models require a scan tool to read the codes, configure the controller and/or clear the light.
