"NO BUS" means that your insturment cluster is not communicating with the onboard computer. Your cars have a "data bus" the same as a personal computer. It is basically just part of the Chrysler computers wiring system.
Try checking plug in connectors in your wiring system. This could possibly be somewhere besides behind the instrument cluster, such as at the computer. Another thing to check is the ground system. I don't know about your particular vehicle, but I have found a few vehicles with a loose ground wire, which was driving the instruments crazy. In those cases, there was a ground wire with a metal grommet attached to the metal body or dash structure somewhere under the dash. I have found on some vehicles it is attached on the left side under the edge of the dash right above the emergency brake pedal.
I hope this helps.
Additionally, on Jeep, Dodge and Chrysler vehicles computers communicate with one another across the "BUS". The bus is controlled by the body controller. Double check all fuses in PDC (Power Distribution Center) under hood and fuse center under dash. May need body controller. "NO BUS" means PCM (Poweetrain Control Module), BCM (Body Control Module), TCM (Transmission Control Module) all computer modules are not communicating with one another.

Take out one of the battery terminals for 1 minute it eill reset all the system then take it to workshop of your preference to check for wires and the body control module. I had the same problem on exactly the same model i have to change the body control module because i leave it like this for almost 2 years and i also blew the central computer so check it as soon as posible

I looked and checked out the wirng cluster in the location in which you provided but all seems to be where it should. there is one wire in which Im concerned about and don't know where it goes, but looks like it had been off for a while and was dragging on the ground. It looks like the same wire that the headlights are plugged in by, but the color code on the two wires are white withh yellow stripe and a black one. it has prongs which seem to plug in somewhere.
Thanks for the help, it helped me. I still have not found out the reason it gives me this problem, but when I took the battery terminals off and put them back on, the problem went away. We have been driving the car all morning and no more problems. Maybe this too will help someone else.
