(Not a A-Body) 2001 Dodge Ram Truck "No bus" Code, Anyone!?

I had a 2000 Ram that out of nowhere developed an intermittent "no bus" on the gauge cluster when I hit bumps. The truck would stutter or die when it happened.

I found it to be a group of ground wires bolted to the front of the drivers side cylinder head that the bolt had come loose and the wires were very corroded.

I also heard that most of the time it is caused by a bad PCM, but at least the ground wires are something that can be checked easily.
