U210B LINCOLN - Lost Communication Between Fuel Pump Control Module 'A' and Restraints Control Module
U210B LINCOLN Possible 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)
- Faulty Fuel Pump Control Module
First diagnose U210B LINCOLN code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
U210B LINCOLN Tech NotesCheck 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).
Cost of diagnosing the U210B LINCOLN code
Labor: 1.0The cost of diagnosing the U210B LINCOLN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
U210B LINCOLN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
U210b Lincoln DescriptionThe 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.
