This means the vehical network is down. Odds are you have a module failure. I would start by unplugging the radio. This seems to be a weak point. There are several modules, asb,air bag, ect. When you unpulg the bad module the no bus light will go out. What 5 amp fuse is inop? I have access to diagrams.

the abs module should be at the center of dash, on the floor. I believe there is a trim piece you remove, then you unlatch the lever and flip it over to unlock it. The bus is down, so abs light comes on. You may try unplugging the inst cluster, then plug it back in....see what happens. If it all comes back and works properly, then there is a connection problem at back of cluster. Possible corrosion on terminals. If not, then you prob. have a bad module on the network.

the bus originates in the inst. cluster. so if it(the bus) becomes shorted, the no bus message appears. Is your truck a base model or does it have alot of options? here is what modules are on the bus. central timer module, radio,air bag module, pcm,overhead console,abs module and inst. cluster. beings the bus originates in ctuster, you need to unplug each module one at a time, till the NO BUS message goes away. That module will have to be replaced. Im gonna include a module and connector location diag. If you have any questions, just email me....

my truck is the base model. why does it only happen when it rains though if the problem is in the dash?

See if your vehc. has the abs module at the driver side firewall area. If so, unplug it and look for water in connector. Its also called the cab. controller antilock brake. It will have brake lines going to it.. If there is water in it, blow it out and look for corrosion. There my have to be wires/terminals replaced.

If you've got the 5.9 or 5.2 I've got a refurbed module like new, would need to be reprogramed with your info. I paid $295 for it with no returns available. My problem with NO BUS ended up being a shorted crank sensor lead.

Dodge Ram 1500, all the dash lights flash warnings of needing service, shuts the truck off, only 8700 miles, my son avoided a collision and this happened, been to the dealership twice already. disconnected the battery, still same thing.

I have a 2011 Dodge Ram 2500. Wipers, headlights will not turn off all gauges not working, dash looks like a Xmas tree. I left the drivers side window down in the rain. Would getting the power window switches wet cause this?
