Thanks guys,
I emailed freightliner and their response was:
Complaint: We have had complaints from the field with RV product line, equiped with
Kysor/Medallion gauges, experiencing the odometer going to zero when the engine ECM is
re-flashed.
Solution: At the time of a repair (or after a repair if proper documentation), any dealer with
authorized Cummins Insite software can set the odometer to the correct mileage.
1. Hook up to Cummins Insite through laptop.
2. Go to Features & Parameters II tab.
3. Select Trip Offset, enter correct hours and mileage (must have written this down from ECM
before re-flash).
4. Click OK and follow normal process to save settings.
In some cases the ECM will NOT allow any upgrades to the Trip Offest function internal to the ECM. Unfortunately, Cummins cannot advise what software will allow the Trip Offset to be altered. Hope this helps.
The tech tried to do exactly what freightliner said but it didn't work.
So be advised if your MH has Kysor/Medallion gauges and a cummins engine this could happen to you
