Help with No Bus

I have been getting the "No Bus" error message on the gauges on my dash very frequently recently. Does anyone know what may be causing this? I'm extremely nervous that I'm going to be caught going over the speed limit, but I won't know that I'm speeding because the gauges aren't working! Please let me know if you have any clue of what may be causing this.

Mine did that intermittently for a couple days a while back. I just banged on the gauge cluster and it went away lol. I've heard that sometimes it's just the plugs behind the gauge cluster get loose so you take the cluster out and hit the plugs with some dielectric grease and make sure they are firmly connected.

had the "no bus" and finally fixed it.

tried to check connectors and clean and apply dielectric grease,
didn't work

checked all fuses,
no bad fuses

finally pulled entire dash off (gauges, a/c control, stereo, glovebox, all plastic coverings, and airbags and steering wheel) and then chased some wires for a while and finally found multiple points on different wires where rubbing had exposed copper. applied a healthy amount of electrical tape and then zip tied wire bundles in place so as not to move and wrapped whole bundles in more electrical tape. put it all back together and cranked her up....Have all my gauges back!

it's a tedious job but fixed my problem
and before I started ripping it apart I isolated the problem to my jeep and not the gauge cluster by taking a buddie's TJ cluster that was functioning and put it in my jeep and it displayed "no bus" so I knew for sure it was the innards of the jeep and not the cluster itself.

hope that helps!
it feels so nice to not have to guess when to put gas in it and to not rely so heavily on the extra gas can in back. Also knowing how fast I'm going is a plus as well.

As of this morning, my jeep turned off this morning when I was driving and the gauges kept flashing and the odo read 'no bus.' the jeep won't start, it's clearly something electrical which is something I know nothing about. Let me know what happens with yours cause as of now I'm car less. Thanks

from what I've read, if the motor won't start and it's reading "no bus" some people have found that it is a faulty crank position sensor...I'd start there.

Thanks I figured it out, I shorted out the whole car because the cord from my subwoofer to the battery fell on my AC hose which was metal. New battery and cords was the fix.

When I got it I figured something was wrong and my Jeep didn't want me to have to start taking the bus.

I think mine was telling me that it wasn't a bus. Because some people have called my Jeep the short bus before...
