OK so my 2016 2500 Laramie has 67,000 miles and we were out on a camping trip about 90 miles from home.

On the way back my idle pulley decided to destroy itself. I got that replaced and a new belt but the issue popped up that I am reading 12 volts or less off the truck.

I replaced the alternator and still nothing. I am getting the following codes.

P0698
P2228
U010c
P1193
P125A

Could the 70 mile trip back home on a bad alternator have screwed something up?

Or are the batteries bad possibly??
