He thinks that the US and reprogrammed Canadian clusters just can't process the odometer message that the Canadian ECU is sending.
Pretty sure they use the same cluster....
Is there are part number on the (Canadian) cluster that was taken out? I could cross reference it to the US part number.

Also, am pretty sure that what the cluster displays is determined by the region/country setting setting in the BIU or ECU, not actual cluster programming...

I'd almost bet that whatever they tried to "program" caused the issue and what ever holds the odometer info and gives it to the cluster to display got boogered up....
