DTC U016C: Lost Communication With Fuel Pump Control Module B

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2013 Lincoln Navigator, 2013 Lincoln MKZ, 2013 Lincoln MKX, 2013 Lincoln MKT, and 2013 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
DTC U016C: LOST COMMUNICATION WITH FUEL PUMP CONTROL MODULE B

Description:  The PCM monitors the fuel pump monitor 2 (FPM2) circuit for the presence of a duty cycled signal. If the FPM2 circuit is fixed at a low or high voltage, the PCM begins to increment a counter. The test fails when the PCM is still not detecting a duty cycled signal on the FPM2 circuit after a calibrated amount of time.
Possible Causes: 
  • FPM2 circuit open or short to ground
  • FPM2 circuit short to voltage
  • VPWR fuel circuit open
  • GND circuit open
  • Damaged fuel pump control module relay
Diagnostic Aids: 
Application  Key On Engine Off  Key On Engine Running  Continuous Memory
