Interesting question. There is a problem with the question however.....IS there a "P", U" or "C" in front of the 4 digits?

It is possible someone messed around the PCM configuration, never saved the original and used another configuation that doesn't fit the model.
Maybe, just maybe the correct As-Built data may fit, providing the original PCM is intact and the original version.
Worste case scenario is an actual PCM flash re-write at the dealer level.
Read the documents.

I guess there must be a glitch in the Forscan software in regards to regen on 6.7L diesels.

The code arrived after completing a regen using Forscan.

Is there any way to clear the EEPROM using Forscan, or is this a dealer only fix?

Thanks.

I had a 2015 F250 that required a "Forced Regen" and already knew the DEF tank heater 1 circuit failed. (In tank heater)
The F250 didn't have any problems like you describe.
Click the "Wrench" and perform a PCM reset, follow the instructions with FORScan.
If the fault persists, then a reflash is the best option.
Smart shop owners that deal with Ford products and have a J2534-2 device, can reflash the PCM with a possible new calibration.
