U054F Invalid Data Received From Side Obstacle Detection Control Module C

Check engine lightUsually off

Some vehicles carry more than two side obstacle radars, adding units for wider coverage of lane changes and crossing traffic. Ford names them side obstacle detection control modules C and D (SODCMC, SODCMD) next to the left and right units SODL and SODR. Its bulletin SSM 51903 covers Ford and Lincoln models of 2021 to 2023 that log U2100 or U3002 in these modules after replacement, when configuration or VIN had not been written. No public manufacturer text uses U054F itself. It signals that module C is transmitting, yet the receiver refuses the content. A newly fitted module whose configuration does not match the car is the most plausible source, ahead of wiring or connector faults. Drivers see side assistance messages, while driving behaviour is unaffected. U024E is lost communication with C; D is U0550.

Likely causes

Module C not configured or VIN not written after replacement
Software level of module C outdated or incompatible
Harness or connector fault at module C

Symptoms

  • Side assistance or blind spot warning message
  • Lane change or cross traffic warnings partly unavailable
