2nd Gen Non-Engine/Transmission 02 Dash gauges stopped working

[RMcPeak]

My 02 dually dash gauges (tach, speedo, fuel, oil, amp) quit while traveling and pulling my 32-foot trailer. The ABS, check engine, airbag, etc, indicators came on. The headlights, radio, turn signals, horn still worked.
After checking for blown fuses in-cab and under-hood, I continued the trip home (approx 2-hours) with the dash gauges not working.
I unhooked the batteries the next day, checked all fuses, found no blown fuses. restarted the engine, all the gauges were working again but the check engine and ABS indicators were still on
After a couple of days of driving the truck, the ABS and check engine indicators went out, truck appears to be running normally.
I haven't found what might have caused this to happen.
Any thoughts? :confused

I would hook it up to an OBD2 diagnostic tool. Maybe you will get lucky and get a code. If you don't have one, Pep Boys or Advanced Auto will usually do it for free.

The instrument cluster is completely electronic with a tiny computer and connects to the ECM using the data network (CanBUS/ODB2/CCD). What you described happens when it loses communications with the ECM. The odometer may report "noBUS". Sometimes the CanBUS connector on the back of the instrument cluster is loose and needs to be unplugged and connected again. I don't know why the ABS light stayed on.

Clean Grounds...Bad grounds can cause intermediate electrical issues.

Thanks for the input and advise, I'll spend some time checking these areas.
