WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The restraints control module (RCM) monitors all deployable devices for a cross link fault between circuits. If the RCM detects a short between any of the deployable circuits, it will store a diagnostic trouble code in memory, flash LFC 12-11 on the air bag indicator and the secondary air bag warning chime will be activated.
