The no bus message is the communication lines for the computer are down causing the NO BUS message in the instrument cluster.

If your vehicle has a 3.7 or 4.7 engine unplug the crank sensor and see if the no bus message is not being displayed. If the message is gone you will need to replace the crank sensor. The crank sensors are know to short out and back feed the PCM which cause the computer to lock up.
