Dodge Repair Questions? Ask a Mechanic for Answers ASAP
This problem can be caused by a number of things like a failing instrument cluster, bus communication issue, intermittent loss of power or ground to the cluster, or PCM issue. The instrument cluster controls the gauges by information it receives from the PCM over the bus communication wires.
When the gauges drop out, does the odometer display no bus?
When the gauges come back, do all the cluster warning lights illuminate for a few seconds then go out?
Does the engine quit when the gauges drop off or does the engine continue to run?
When the gauges drop off and the check gauges light turns on, have a look at the digital odometer and see if it displays "no bus" instead of your current mileage. This information is needed to help you diagnose this.
