Post subject:  "No Bus" Message

Today i was driving my CRD and all the lights in the dash went on and the "No Bus" message was showing on the odometer... Something else was showing on th EVIC as well, like J1850 No bus error

The jeep continue to run as usual, but nothing was working in the dash. The radio was still working.

No recent changes were made... i washed it yesterday with pressure hose. I got ECO Tune from green diesel engineering few months ago.

I tried to find an answer, but nothing was clear, so i'm asking you guys.

Thanks

had the same exact thing happen on my 05. Turned out to be the passenger side airbag seat sensor wiring under the passenger front seat. The rails had cut the wires, causing the NOBUS message, no gauges or instrumentation functioned. Soldered the wires back together, been good for the past three years.

Had a slightly different experience. Every warning light on the dash lit up and it wouldn't start. Turned out it was a loose pin in a wiring connector to the ecu.
Having read other threads, the general rule seems to be that if it lights up light a christmas tree, it's most likely a simple wiring fault.
Best of luck finding it.
