Normal Operation
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition is in the ON position, the (PAD) indicator prove-out period is initiated by the RCM. The RCM briefly activates the (PAD) indicator to verify to the occupants proper functional operation of the PAD indicator. Refer to AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM SRS .
If the restraints control module 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.
