What are the Possible Causes of the DTC U210C Lincoln?

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
  • Event Notification Signal (ENS) harness is open or shorted
  • Event Notification Signal (ENS) circuit poor electrical connection
  • Radio frequency interference or electromagnetic interference
  • Faulty Restraints Control Module (RCM) 2
  • Faulty Fuel Pump Control Module

Code Tech Notes

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 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).

What Does the U210C Lincoln Code Mean?

The Fuel Pump Control Module 2 monitors the duty cycle and frequency of the signal it receives from the Restraints Control Module (RCM). The fuel pump control module 2 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 2 sends a 40% duty cycle signal on the Fuel Pump Monitor 2 (FPM2) circuit to report the concern to the Powertrain Control Module (PCM). The test fails when the fuel pump control module 2 is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time.
