Airbag Code 27 — Air Bag Deactivation (PAD) Warning Lamp Inoperative
Airbag Code 27 — Passenger Air Bag Deactivation (PAD) Warning Lamp Inoperative
Normal Operation
The restraints control module (RCM) 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 RCM monitors the PAD switch warning lamp for open or short to ground conditions. If the RCM 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
A PAD warning lamp inoperative fault could be caused by:
- an open or short to ground on circuit 1113 (YE/LG).
- a damaged or burned out PAD indicator.
- a damaged or inoperative PAD lamp.
- a damaged or inoperative RCM.
- a blown PAD switch I/P fuse.

I have commented many times on this, as have others, you could do a search. Its a DIY to replace the PAD switch if you are comfortable working on the airbag system. It took me 15 min and Im no mechanic but if you are unsure have a dealer do it. I disconnected the battery for 30 min or so before beginning just in case. Have you or a previous owner kept the AB switch off (which keeps the off light 'on' ?) I did/do for a carseat and think mine burned out just from the light being always illuminated..

If it were mine, I would just replace the bulb. It's cheap and easy enough to do and will rule out any bulb issues, at the very least. Then go from there.
FWIW, when the bulb in my PAD switch failed, it was an intermittent thing. What was happening was that one side of the filament inside the bulb was making/breaking contact. The factory bulbs can fail in different ways.
