ECM Connector Problem
"NO BUS" means that the communication system between the computers has stopped working.
The PROBLEM WITH 2001 DODGE RAM 1500 PICKUP. THE DEALER Asks 100 DOLLARS AN HOUR TO FIGURE IT OUT.
Hi I have a 2000 Ram 1500 that had the same problem.
In the Electrical Power Distribution Center ( The fusebox located in the engine compartment )There is one big connector with a screw down through it that loosens or tightens the connection.
This problem is noticed by many dodge vehicle owners. For some unknown reason that connector stop making good contact with at least one or 2 of the pins.What has to be done is take that off, clean it up, and put it back on and everything will work fine.
What is suggested is clean it better with contact cleaner and coat it with some dielectric grease and see if it stands the test of time. This specific problem generally seems to be some kind of electrical contact problem and not the Computer or any other major part.
I had the same "no bus" all gauges dead on my 2000 ram 1500. After looking at all the different answer posted I tried all of them and this one that worked.
I tried disconnecting the main plug held down by a screw in the fuse box on the engine compartment. I disconnected, blew the plug and the connect with compressed air, plug it back in tighten the screw and my truck is fine again. Everything works as it should.
Hope this helps others too facing this same problem.
