2015 tradesman 1500 electrical issue

[str8shootndad]

I have an issue that is intermittent. My dash lights would flash once, I'd get an alarm chime and it would say, service trailer brake system or battery saver mode. Runs fine except for this. Any ideas before I put it in the shop for $$$?

Check battery voltage when running, should be 14v on your display.

I did and it is 14V. Just don't want to pay $$$ in a shop if someone here has a similar problem or a solution. Thanks tho

Can it be the ecm?

Yesterday I came to a stop sign and the lights flashed once, a chime sounded and it said service 4 WD system. I'm at a loss here, anyone have an idea what's going on. Truck runs fine except for these ghost flahes and different codes. Help...
