Dodge Ram 1500 Van engine cuts out when hot, no bus lights during failure on Dodge Ram 1500 Van

Some Dodge Ram 1500 Van owners report experiencing issues with their engine cutting out when hot and displaying a "no bus" message. This "no bus" error often points to communication problems between the vehicle's electronic control modules (ECMs), which may stem from a faulty ECM, damaged wiring harness, or failed common sensor. Additionally, the engine cutting out could be linked to a malfunctioning ECM that isn't receiving the necessary power or 5-volt reference, and checking the cleanliness and seating of the ECM connector may help resolve this issue. Furthermore, if the engine rattles loudly after reaching operating temperature, it could indicate a problem with a valve lifter, particularly a worn-out lifter roller bearing, which can cause the notorious "Hemi tick." It is advisable for owners experiencing these symptoms to inspect the ECM, wiring, sensors, and valve lifters to effectively diagnose and address the problem.
