Odometer Message

Posted

Will a 99.5 Dodge 2500 flash ANY type of message on the odometer? With no key in, I am reading/getting  NO BUS on the odoemter.

I actually had something like that happen to me. Didnt even notice it said anything until i was already out of the driveway and none of my gauges worked. NO BUS on the odometer and it said something else on my overhead display i cant remember now. I talked to one of the techs we have here and he was explaining to me how the BUS is your signal that is routed pretty much throughout the truck and allows the modules and computers to talk to eachother. I had no idea what a BUS was then and honestly i still dont know.

 

SoI did some digging into it and found a bunch of wiring diagrams related to the fuse boxes and whatnot. Looked in the underhood fuse box and found that the 50A fuse for this was blown. I wish I could remember which fuse it was but its a 50A under the hood. Oddly enough this problem "fixed itself" so to speak? I never replaced the fuse and I have one in my truck ready for me to replace it when I get around to it or feel like it but honestly I have no idea what happened and no idea where to even look for this. I will definitely be following this maybe get some insight to my trucks problem but like i said its doing fine right now and its been probably close to a year now since that happened to me.

 

And the reason i havent changed the fuse honestly is because it was like 5 bucks for that fuse and i dont wanna blow these pricey fuses a bunch of times just to diag this problem.

Here is the CCD Network bus. You can see the Central Timer, Radio, Instrument Cluster, Airbags, ABS and Overhead console. The PCM is the master controller of the CCD network. ECM is companion module.
