Fault code P2506

[tmc553]

Okay, I found out that an OBD-II P2506 fault code means ECM/PCM Power input signal Range/performance. Which tells me absolutely nothing. Time for a new one? Any input/advice/suggestions?
Thanks,
Tom

By googling, it could be a low battery. Only suggestion I've found. There was another question on this site that was like yours and it got absolutely no responses.
