Pinpoint Test N: 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 inoperative Passenger Air Bag Deactivation (PAD) switch warning lamp 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 ECS module.
- an open PAD switch I/P Fuse 22 (10 A).
