Intermittent start problem. Trucks runs good can die when driving with no notice, sometimes will start after one minute, Mileage blinks then shows (No Bus). I have no code with OBD2. Had it in a dodge repair shop, no luck finding problem. No mechanic seems to know what (No Bus) means. Can you please help.
Essentially " No Bus" means somewhere communication w/ the various modules (computers) was lost. This could be a controller actually causing this or an intermittent short or open along the bus wiring. Its a very hard problem to diagnose and can be labor intensive, unless the problem occurs when a tech is looking at it!
