This might be a little different, but the concepts still apply here. And the black does seem to be a good ground. Wondering if it's worth taking the PCI bus wires out of the PCM connector and rechecking for communication, just to eliminate the network from the equation.

Sometimes when i start the truck the odometer flashes a few times then displays "no bus" and none of the guages work.
The truck does start every time like it should. Whats happening to my truck? Thanks Danny. Find all posts by MoparMiami. Sponsored links. Join Date: Feb Location: Dekalb, IL. When that happened I pulled the gauge cluster out and reseated it. It has worked fine ever since. If that doesn't fix it you may need to check your grounds, but the gauge cluster is an easy place to start.

I've checked all fuses and such they seem to look fine, the coil and distributer cap are all on tight and there isn't any fuel pressure on my fuel rail. What's wrong with it? G A answered 4 years ago. Check all of the PCM connectors, make sure they are tight and plugged together properly, check main power box connectors, ignition switch connections etc.

It cuts off when coasting and will not start back up like it has no fire. Mostly does it when it's really hot outside. Could this be My truck is saying No bus I replaced my computer still saying No bus.
This light just started randomly coming on. When it does if I put it in park I can't shift gears out unless I turn off vehicle.

Update: Still not fixed. Lots of good info here. Thanks for everyone's input. The weather is pretty nasty here now. When it clears up, I am going to put the old cluster back in and go over the wiring once again and see what I could find. I have heard several people mention there is a connection in the fuse block that has a bolt through it that often corrodes.
I was going to remove and clean that, and the connections to the engine computer on the firewall. I will post the problem whenever I find it! I'm not entirely sure but I think the NOBUS display is due to a failure to receive the readout for the instrument display, generally either a short or a bad connector will conk ou the whole instrument panel. Most panels come apart fairly easily with a few screws that retain the cluster, then another 4 or so that hold it in.
I would check the connection if there is no issue at the fuse, there may have been a problem that developed somewhere. Purchased 04 Quad Cab Dakota brand new. Recently the original batt failed, lasting for 10yrs and K. Seems as if it was insufficient voltage. What you have is no communication between the instrument cluster and the other control modules in the vehicle. Since you have replaced the instrument cluster already then it is most likely due to a wiring problem.
The truck uses a two wire communication system and if one of those wires goes out then the whole system is down. Most likely a mouse chewed through one of the bus wires on your truck and it needs to go to the dealership because they are the only ones who can properly diagnose a bus failure.
Theres been some excellent advice given to to you so far. First off if i was you id put the old dash cluster back in bec the dodge man is excatly right some cars are like that the comps are programmed to the cars needs and work like a team player. You change one may screw up the whole system. Highly believe that it was like the one man suggested to you could of been a mouse etc chewing away. Plus dodges have crappy wires that do basically corrote inside and get affected by cold temps etc.
Another thing is theres wiring harness's that are very tight and bec ppl bump cars etc they strecth the wiring and that causes wiring failers. Theres no thing forsure like another man suggested its a two wire feed return system and your cluster isnt reciveing a signal from one of those wires.Sp racing f3 gps wiring
I do believe that problem is probally easy to figure out bec its just a matter of knowing what these wires are and tracing them.Why don't fictional characters say "goodbye" when they hang up a phone?

Dodge Ram. Why does your Dodge Ram odometer say no bus? Wiki User Hi I have a Ram that had the same problem. For me in the Electrical Power Distribution Center The fusebox located in the engine compartment I have one big connector with a screw down through it that loosens or tightens the connection. Well for some reason that connector wasn't making good contact with at least one or 2 of the pins. I took that off, cleaned it up, and put it back on and everything worked fine.
I'm going to clean it better with contact cleaner and coat it with some dielectric grease and see if it stands the test of time. From what I've gathered from many peoples posts is that this specific problem generally seems to be some kind of electrical contact problem and not the Computer or any other major part. Hope this helps someone.
Answer I had the same "no bus" all gauges dead on my ram Was disconnecting the main plug held down by a screw in the fuse box on the engine compartment.Plymouth middle school supply list 2019
I disconnected, blew the plug and the connect with compressed air, plug it back in tighten the screw and my truck is fine again. Everyhing works as it should.
Dodge Ram cluster not working, no gauges, read "No Bus", runs fine?
The wires in the steering column are bound quite tightly, and do not allow for the vertical movement of the steering column. Answer your computer is dead.
Answer This does not have to be a computer problem. This can also indicate a loose fuse or a simple bad connection. The bus is simply the ground for the electrical devices in the vehicle. It's a fundamental rule: go for the simple stuff before you spend a pot of money on the complex.
Answer Had a similar problem and the parking brake was the problem and needed adj. A simple nudge until hearing the parking brake "click" was a quick temporary fix.I have a Dodge the message center says"no bus" the gauges don't work and all the lights are on steady on the dash.
Every this runs and works fine? Mike answered 9 years ago. Sounds like your instrument cluter module shorted. You can do a module status check to see if the IPM is coming up. Need specialised tools for this proceedure. My 03 dodge diesel is cranking but won't go move and it shows no bus. What does that mean? So i got this dodge with a v No spark, No fuel. No Start.
Turning key on and off no fuel prussure at rail. ASD Reley alr Already Replaced brake switch. Had brake lights on way to work when i left I had no brake lights, however I still had my flasher. Pickup a brake switch changed it and still no brake lights.

I have a dodge ram 5. In the last month the truck suddenly shuts off while driving 3 times. After multiple attempts min it turns on. The dealer said they can't find anything wrong and It could be the pcm they need to check the truck when it's dead.Cid 226
Is the pcm the problem or should I look somewhere else? Can the pcm be flashed off the car? KCRam Mt. Arlington NJ Posts: 3, September This is a very common problem with that generation of Ram. NO BUS means the dashboard has lost communication with the computer. Search on "no bus" here in the forums and you'll get the info you need. I looked up the other posts and have cleaned the connections at the pcm, checked the fuse box under the hoodand checked the connections inside the truck above the kick panel.
I sprayed electric contact cleaner on all the connections removed, cleaned and reinstalled the fuses big black ones The truck stopped again today and would not restart after a bunch of attempts and about a half hour it started. Took the truck to the dealer, couldn't find anything wrong and said to take it when its broken. What do I do now, any suggestions?Bored piles
February I have the same problem with my Dodge and no one can fix it. Help, please. Replace the "pcm" powertrain control module, that's what solved it for me. Purchased a rebuilt one from "auto computer exchange?
