Hello I have a 2003 Dodge Durango 4.7l 4wd SLT and a few days ago all of my warning lights on the dash came on and my gauges all stopped working with the odometer saying "no bus". The Durango still runs perfectly fine though, I've read around on a lot of forums of people having similar issues but there cars are stalling our or not starting, mine still starts right up and runs just fine there have been no mechanical issues just all the warning lights are on and the gauges don't work. Has anyone encountered this issue? I pulled another pcm from a 2002 Durango from a pic-a-part but the problem remains is this a bad cluster? Thank you

 

Bad communications from PCM to cluster. Swapping the PCM didn't fix it, so, that ain't the problem. Another possibility would be the central timer module, or simply a bad connection somewhere in that chain.
