WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The RCM will only display diagnostic trouble code B2792 as a continuous fault.
The RCM monitors the air bag deployment circuits for a short to another deployment circuit. The RCM carries out this check only at startup, so an ignition cycle is required for any changes to take effect. This is a stored DTC fault only, not available during self test. During each ignition cycle, if the RCM detects a cross link fault on any deployment circuit, it will store diagnostic trouble code (DTC) B2792 in memory and flash lamp fault code (LFC) 72 on the air bag indicator. The RCM will also display the lowest priority device indicating the shorted component.
