Normal Operation

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The Restraints Control Module (RCM) monitors all of the impact sensor circuits for faults. If the RCM  detects one of the following faults on any of the impact sensor circuits, it will store DTC B2296 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
