Normal Operation

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.

The front impact severity sensor provides data to the RCM for use in calculating impact severity. The front impact severity sensor is used by the RCM as an input for deployment determination. Refer to AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS) .

The RCM checks the impact sensor circuits for faults. If the RCM detects a fault on either of the front impact severity impact sensor circuits, it will store diagnostic trouble code (DTC) B2227 in memory and flash lamp fault code (LFC) 42 (or higher priority code if one exists) on the air bag indicator.
