Normal Operation
The RCM monitors all 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 IPC to illuminate airbag 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 PAD switch circuits in a Crew Cab vehicle.
