Normal Operation
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. 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 correct 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 illuminate the air bag indicator.
