Airbag Code 27 Update
It was a burnt bulb on the Passengerside Air Bag on/off switch. Here is the Part number and specs on the bulb I got from Radio Shack and Soldered in:
Part Number:2721141 or 271-1141
12volts 25mA with 1 3/4 hookup leads.
The bulb is slightly smaller but just as bright and it has 2 wires instead of 2 metal contact wires. I just soldered it in took 10 mins and all is good.Total cost $1.39 vs what ever the switch would have cost. Here is the technical info:
Lamp Flash Code (LFC) 27 description from the 2000 service CD:
Pinpoint Tests — Air Bag Supplemental Restraint System (SRS)
Pinpoint Test O: LFC 27/DTC B1884 — Passenger Air Bag Deactivation (PAD) Warning Lamp Inoperative
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.
A PAD warning lamp inoperative fault could be caused by:
l an open or short to ground on circuit 1113 (Y/LG).
l a damaged or burned out PAD indicator.
l a damaged or inoperative PAD switch.
l a damaged or inoperative RCM.
l a blown PAD switch I/P Fuse 22 (7.5 A).
l an RCM internal concern.
Hope this helps,
