No Bus flash

I know a little about electronics but I have a message flashing " no bus" where my odometer is. Does anyone have a clue what this could be. I was thinking its my instrument panel due to the fact my jeep just quit running

Pull that cluster out of the dash and make sure all the connectors are tight behind it; I've heard of other people on the forums having similar issues. You may also put a bit of dielectric grease in the harness housing to promote a good connection.

Basically, the PCM isn't communicating with the gauge cluster, thus the "no bus" message. It could be a loose connection at either end there, or something fried... hard to say until you start troubleshooting.
