2002 Dodge Ram 2500 No Bus indication wont start
I have a 2002 Dodge Ram 2500 van with 110k miles, parked it in the driveway last night went to leave this morning wont crank, sounds like its going to start but doesn't, I'm getting a "NO Bus" indication on the OD panel, and error codes 920 921, and 999. I have looked at all wiring everything seems to be okay found no corrosion, any ideas ????
