2018 RAM 5500 - N0101 Code?

[F350Cummins]

Make sure we know the year of the truck: 2018 RAM 5500

What transmission: AISIN

What modifications does this vehicle have: 100% Stock

This is a truck under FMCSA guidelines, and during inspections can't have a CEL on.

A quick google search does not turn up an N0101 code.

A P0101 is a mass airflow code, and it was changed in a failed attempt to clear the code.

This truck has been an ongoing "Battery Saver Mode" issue truck, and the last work performed was by the dealer about 3 months ago (20K miles ago), including a new TCM, a new cluster, new grid heater, new grid heater controller, 2 new batteries, a new intelligent battery charge harness, and a new ECM.

We are not even sure that the battery saver mode was repaired, as it would only come on when it was cold, and the dealer dragged their feet so long the weather warmed up.

So Any Ideas on an N0101 code? (Screenshot attached reflecting code in the computer)

What can I look at?

Before we send this back to the dealer and have them sit on it for a month again.....
