What does no bus mean on the odometer

No bus means the bus is not operating properly. It means no communication between the modules inside your jeep. All modules inside the jeep (A/C control, radio, onboard computer or trip computer, body control, etc) communicate with each other by means of a wire called bus. Check that wire.

2000 jeep Cherokee no bus

Hi there:

The bus is the network the computers use to talk to each other. When it comes up in the mileage display this means that the network has shut down. You may have damaged wiring, a shorted cam or crank sensor, or you got a defective PCM.

Sometimes, the problem you are having is with a bad computer. Most likely this is being caused by a bad engine computer and will need to replace in order to solve this issue. The PCM is located in the engine compartment next to the air cleaner assembly.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2000 jeep grand cherokee laredo showing code p1686, p1687, p1688, geuges go down, all warning lights come on, with time, the geuges comes on, and the warning lights come off, all but the security key...

Diagnostic Fault Code (DTC) P1686 has a generic description of "No SKIM Bus Nessage Received".
Diagnostic Fault Code (DTC) P1687 has a generic description of "No Instrument Cluster Bus Message"

P1688 is either not a valid code for your vehicle, or the manufacturer failed to provide specific information for it.
Basically, what is going on here is that you have a problem in your computer network communication bus. Or to put it more simply, the "phone line" is down. Your computers in your vehicle are having problems talking to each other.

"SKIM" stands for Sentury Key Imobilizer Module (AKA security module). The Instrument cluster and the SKIM are not communicating with the Powertrain Control Module (PCM) for sure, and possibly also not communicating with the Body Control Module (BCM). There may also be problems with other modules that share the same data lines.
This MUST be diagnosed with a scan tool that can access the entire computer network. You must find out which modules can communicate with the scanner and which ones cannot. This is necessary to determine the possible location of the fault.

My 2000 Dodge Ram 1500 stalls out while I'm driving and a No Bus signal comes on the odometer reading. It starts again usually after a few minutes but how can I fix this?

i had a jeep that flashed that and wouldnt start i ended up replacing the pcm(engine computer) after checking the wire harness and connection if im not mistaken the pcm is in a place where it can be exposed to water so it might have water damage hard to tell without the truck but the bus signal is a state of health from the computer like a self diagnostic of it so without the signal it wont run hope this helps good luck

Bus communications stop only when running

"No Bus" is a very common message on chrysler vehicles. The first thing to try is a complete computer rest. This can be accomplished by disconnecting the negative battery cable, followed by the positive cable. Then Take the two cable ends and clamp them together for about 3 minutes. Reconnect in the reverse order and start the vehicle.
I have had a high rate of succes with this solution. Sometimes, the "no Bus" message is actually caused by a loss of communication between computer modules due to a true failure, but in MOST cases, it is simply a glitch in the system that confuses the cluster and requires a complete reboot such as this

Check engine light comes on and then the gauges flat line and drop, then the odom reading says no bus?? what does that mean??

Not sure about the gauges problem, but "No Bus" means that the PCM or the computer can not communicate.
