I have a 2020 3500 Larmie long bed. Love the truck!
i am cruising down the highway with a 6000 lb trailer under tow.
all of a sudden i get a series of messages flashing at me: (1) acc/fcw unavailable service required, (2) service electronic stability control, (3) service antilock brake system, (4) 4wd temporarily unavailable and (5) trailer brake not operational (dont recall exact words on this 5 th one).
i check my remps (coolant, tranny, oil etc) and i am all good but i pull over anyway. I can manually engage the trailer brake through the brake controller but it feels like it is not working when i press brake pedal.
i stop and turn off engine. I turn it back on. Warnings go away but the check emgine light is on. But no messages/warnings. I can still manually engage trailer brake. After restart 4wd is available. As i am in the middle of Nevada, and my temps arw good i decide to continue on I-80 to Salt Lake City.
i make it (good) but an hour later, same thing. I stop again. Turn off engine. Turn back on and warnings/messages go away but check wmgine light it still on. This repeats one more time.
Thoughts on what went wrong/issue?
