TKers

I cleaned and did the G218 Ground issue. Unplugged trailer. Still has service trailer. Unsure. No codes being thrown.

HI, i never had these issues before. While towing my trailer for 400km using cruise control. Service Trailer Brake , Service StabiTrak, and my ABS light comes on, and kicks out cruse control. I have read about the G218 Ground, and the Starter head shield ground. Anything else i could look for? I am on the start of a long road trip and go figure hey This is on a 2017 3500 HD 6.6 Duramax L5P.
