So my girl has a 17 rubi unlimited with 36k on it. We wheel it hard and she likes to put it in deep water. I’m getting the traction control light and derate. I bought a TD2 and unlocked pcm. I was getting cam sensors. Replaced both. Started getting loss of communication to trans module. So we took it out with doors and top off, I had to pressure wash the inside. I replaced the TCM and flashed correctly. I also replaced the wheel speed sensors. I have ohmed out the cam sensor harness and have no issues. I did find three slightly bad rockers and replaced those as well. At this point, I’m getting communication problems with all controllers. Could this be a ground issue? I have checked all that I could find. I have exhausted The search function on the net. Any help is appreciated.
