Pinpoint Test AK: LFC 27/DTC B1884 - 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 can 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 switch.
- a damaged or inoperative RCM.
- a blown PAD switch I/P Fuse 22 (10 A).
- an RCM internal concern.
