Got a rather weird one and looking for any insight.
2003 DII
No engine codes or check engine light but I noticed recently that the odometer is "flashing" not the trip but the actual miles... never seen this before.

During my last oil change I disconnected the battery to see if perhaps this would correct it but alas it's still flashing...

Anyone have any ideas?

The BCU on those trucks is programmed to "match" with the Fuel Injection ECU and odometer.

Generally the odometer only flashes when one of those units is not paired.

Will, thanks for responding... everything is original on this truck, is it a sign of something failing?
