SOURCE: no BUS on odometer
I used to have the NoBUS show up on the odometer also, but always while driving. The immediate fix was a sharp rap on the top of the cluster with my fist. To fix it permanently, I removed the cluster,cleaned the contacts both cluster and harness with spray contact cleaner, then applied some dielectric grease to prevent any further corrosion.

SOURCE: wont start my odometer blinks
From the official Durango shop manual......(abbreviated)
Self Diagnosis Test
Vehicle key position is OFF ,or able to pull key out.
Hold in the trip odometer button (dont release yet)
Turn key to the ON position (one notch), but DON'T try to start the engine
Continue holding the trip button for about 10-12 seconds until CHEC appears in the odometer display
Release the trip button.
Series of three digit numeric failure codes may appear.
If no failure message appears, the self diagnostic test will proceed as described in step 6
110- cluster CPU,RAM,EEPROm failure, replace cluster
900-CCD data bus not operational, check CCD data bus connections at cluster, check the cluster fuses,check the CCD data bus bias, cehck the CCD data bus voltage, check the CCD data bus terminations.
920-cluster is not recieving a vehicle speed message from the PCM, check PCM software level and reflash if required, use the ($2500+) DRBIII scan tool to verify the vehicle speed message is being sent by the PCM
921-the cluster is not recieveing a distance pulse message from PCM,check PCM software level and reflash if required, use the ($2500+) DRBIII scan tool to verify the distance pulse message is being sent by the PCM
940-the cluster is not recieving an airbag lamp-on message from the ACM, check the CCD data bus connections at the ACM, check the ACM fuse.
950-cluster not recieving an ABS lamp-on message from the CAB, check CCD data bus connections at the ACM, check the ACM fuse.
960- clsuter not recieving a PRND21 message from the TCM, check the CCD data bus connections at the TCM, check the TCM fuse.
999-An error has been discovered, record the failure message, depress the trip odometer reset button to continue the Self-Diagnostic Test
Instrument cluster will test each segment of the odometer (all first, then each one seperately)
The instrument cluster will return to normal operation at the completion of test, if ignition switch turned off, or a vehicle speed message indicating movement recieved from the PCM on the CCD data bus.
Hope that help you or anyone else in future.

SOURCE: No Bus Error
All the modules are connected together to communicate with each other via the PCI bus. It is possible that one of the modules is pulling the bus down.Since the vehicle won't start it could be any one of the modules. It will be a process of elimination to find the faulty one by disconnecting them one at a time. Here are a few, powertrain control module (the one you replaced) Instrument cluster, overhead console, anti-lock brakes, airbag. Since the cluster unplugged wont read anymore, just try to start the vehicle to see if that was the one. Otherwise see if the odometer message of "no bus" goes away after each one is unplugged.

SOURCE: odometer reads no bus
check bulkhead connecter for corrosion, cluster is your body controll module, losing signal to fuel pump module , and pcm, thios is a communication issue, volt meter wil help, back probe diagnostic connecter, pin 7, white wire, to see if signal is there, GOOD LUCK RDJRP
