Re: 450J Speed Control Not Working, Dozer won't move
I've got it to work but don't think it's a permanent solution. To get it out of idle, I would spam the "next" button on the TCU while moving the parking break up and down every so often until I hear the engine rev up. All of the breakers and Relays worked fine.
