Maybe he smoked a fuse.

LFC 27/DTC B1884 Passenger Air Bag Deactivation (PAD) Switch Warning Lamp Inoperative


Normal Operation

The air bag electronic crash sensor (ECS) module has the ability to deactivate the passenger air bag under certain conditions. When the passenger air bag is deactivated, the passenger air bag deactivation (PAD) switch warning lamp will be illuminated.

The ECS monitors the PAD switch warning lamp for open or short to ground conditions. If the ECS detects an open or short to ground condition on the PAD switch warning lamp circuit, it will store a diagnostic trouble code (DTC) B1884 in memory and flash a lamp fault code (LFC) 27 (or higher priority code if one exists) on the air bag indicator.


Possible Causes
An open or short to ground on Circuit 1113 (Y/LG).
A damaged or burned out PAD indicator.
A damaged or inoperative PAD switch.
A damaged or inoperative ECS module.
A blown PAD switch I/P Fuse 22 (7.5A).

U da Man [img]/ubbthreads/images/graemlins/laugh.gif[/img], thanks for the quick response... I did notice the passenger light was not on any more, but I thought is was due to the general malfunction of the system [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: Air Bag code 27--What does it mean?

Go to radio shack and get a 1/8" LED. Solder it in place of the blown bulb in the switch and the code will go away.

Re: Air Bag code 27--What does it mean?

I used a spare dash light bulb I had laying around to fix mine in my F250 when it went out. I actually had both the one in the dash and the one in the passenger module go out at the same time. So I got the annoying Beep from under the dash board.

my fix

I bought multiple LED's and one pack of 12v mini bulb from Radio Shack. The LED bulbs burned out and/or didn't clear the airbag light. The mini 12v lights worked great part # 272-1099 and there is three per pack. Mine is fixed good luck on yours.
