Event Notification Signal
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
In the event of a crash, the RCM provides an event notification signal to the fuel pump driver module(s) to disable the fuel system.
The RCM does not monitor the event notification signal circuit for faults and will not set a DTC if a fault occurs.
