Check the harness for routing, alterations, incorrect shielding, or electrical interference from other systems. The Event Notification Signal (ENS) is used to notify the fuel pump control module 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 monitors the ENS signal by sending a 12V low current signal on the ENS circuit to the Restraints Control Module (RCM).

|U210B LINCOLN code description

The Fuel Pump Control Module monitors the duty cycle and frequency of the signal it receives from the Restraints Control Module (RCM). The fuel pump control module determines if the signal on the Event Notification Signal (ENS) circuit from the RCM is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module sends a 40% duty cycle signal on the Fuel Pump Monitor (FPM) circuit to report the concern to the Powertrain Control Module (PCM). The test fails when the fuel pump control module is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time.
