2015 f150 3.5 eb 95k. "Service charging system now" message comes on the dash 30 seconds after starting, then battery light stays on all the time, It IS charging.
It has codes P0625 and P065B.I checked continuity on the 2 wires going from the alternator to the PCM plug both checked good. Fuse #38 also good, also does have power to alternator from PCM.
The battery and alternator were both replaced and made no difference. I suspect the PCM is the problem but not sure how to test it.
