Normal Operation
When the ignition is in the ON position, the passenger air bag deactivation (PAD) indicator prove-out period is initiated by the restraints control module (RCM). The RCM briefly activates the PAD indicator to verify to the occupants proper functional operation of the PAD indicator.

If the RCM detects an open or short to ground on the PAD indicator circuit, it will store diagnostic trouble code (DTC) B1884 in memory and flash lamp fault code (LFC) 18 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A PAD indicator circuit open or short to ground can be caused by:
- wiring, terminals or connectors.
- a faulted RCM.
- a faulted PAD indicator.
