The Event Notification Signal (ENS) is used to notify the fuel pump control module 2 of an event requiring the fuel pump to be disabled. This signal is used instead of an Inertia Fuel Shutoff (IFS) switch. The fuel pump control module 2 monitors the ENS signal by sending a 12V low current signal on the ENS circuit to the Restraints Control Module (RCM).
