totally normal I have 4 alternators and 6 batts and my truck does the same bs...damn fuel economy modes

There's a way to turn disable that feature quite easily, it's been posted on here before and since the summer if memory serves.

Enjoy your Florida Christmas Angel!

Is it under "RVC?"

I'm looking for the thread but can't seem to find it.

I couldn't either so I just looked it all up again and got the proper terms.

The system is called Electrical Power Management or EPM for short. Coming off the negative battery cable, the Battery Current Sensor is right in front of the battery and attached to the battery tray. It has a 3-prong plug and is under an A/C line. Unplug it and maybe tape the ends and THAT IS IT!!! No codes, the system reverts back to full time operation.
