Normal Operation

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The Restraints Control Module (RCM) monitors all Supplemental Restraint System (SRS) device connections. If the RCM detects a connection or device connected that is not stored in memory or is not configured for the component, the RCM sets a DTC and sends a message to the Instrument Panel Cluster (IPC) to illuminate air bag warning indicator.

When a new RCM is installed, it must be configured. Configuration tells the RCM which SRS components the vehicle should be equipped with. A vehicle may be equipped with the wiring for a specific SRS component, but not equipped with the actual component. If the RCM is configured for certain SRS components not  to be present, but detects that those circuits are in use, "incorrect component installed" DTCs may be set. An example of this would be installation of aftermarket accessories on the unused Passenger Air Bag Deactivation (PAD) switch circuits in a Crew Cab vehicle.
