Diagnostics plug question
Like a lot of trucks, my E log is connected to the diagnostic port. I occasionally get the red triangle due to connectivity problems with the ECM, being my truck is a little older, 2010 (so they say).
Our company elog guy is telling me it has to do with the ground, and that I should tap into the center wire and run it to ground. I am leery about doing that. Does that sound like a half decent idea?
