What does an error code NO BUS mean on a 2001 Jeep Cherokee?

Answer 1

Instrument cluster panel is in need of a dealer item they call a "PIGTAIL"...It's a $35.00 dealer item that costs $1200.00 to put in on account of tearing down the entire dashboard of your Jeep. It basically is the link between your engine computer and the dash. Little piece of plastic and wiring components. you have a fuse either missing or blown. I disagree: this "code" that is displayedby the odometer means there is a connection failure between the gauge cluster and the ECU. this NO BUS is often accompanied by malfuntioning gauges, the check engine light, and the airbag light, although exact gauges and lights may vary. THE SOLUTION in most cases is to remove the gauge cluster and clean the contacts of the cluster. The application of dialectric grease to the electrical contacts will also help greatly. Once the connection is passing voltage on all circuits, the gauges will imediately return to normal without needing a hard reset of the ECU.
