Check the main wiring harness at the fire wall bulk head connector for corrosion. All power enters cab here. Use dielectric grease on the connector.

A no bu5 message appears on the dashboard


that message is probably "no bus" which means the instrument panel is not communicating with the body computer or engine computer.
It could be a bad connection in the wiring or a problem with the cluster.
You can do an internet search for "no bus" for details.

My 2001 dodge durango dies while driving down road


Could be the Idle Air Control on the throttle body. A simple, low cost fix. Most auto stores carry the part.

What is the problem when it says no bus or no bu5 not sure which it is but it pops up where the mileage is and the check engine light comeson


Next time that check engine light comes on stop at auto zone or advance auto and ask them to read the codes from your ECM. That will tell you where the problem is.

1999 dodge durango slt stalls but restarts (no bus)code shows on the odometer.the truck feels almost like it is running out of gas right before it stalls. could this be water in the gas?


It could be water in the gas.. Get some "dry gas' aditive and follow directions..
It could also be the fuel filter.. Try replacing it..
I have seen this happen on several Dodge's..
The fuel filter gets clogged and choked the engine at idle..

Good luck..

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.

Wont start my odometer blinks and says no bus


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


Code Chart

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

Step 6
Instrument cluster will test each segment of the odometer (all first, then each one seperately)

Step 7
Bulb test

Step 8
Gauge test

Step 9
test completed

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.
