U210C - Lost Communication Between Fuel Pump Control Module 'B' and Restraints Control Module
U210C 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) 2
- Faulty Fuel Pump Control Module
How is the U210C code repair?Start by checking 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 connector's pins.

U210C MeaningThe 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.
