10 days ago I replace one battery and a alternator in my 03 super duty. I keep having the batter light flicker on and off then stays on. Everyone I talk to said that I needed to replace the other battery which I did today. The light was still on so I went to ORilleys and got the above code and low voltage. However the batteries and alternator passed the scan test.

Any suggestions on what the problem is and how to reset the PCM.
