Is there any way possible that they reset the odometer when messing with wires and such? I have our title of course with miles when be bought it but we can't figure out what has happened!
Any ideas and sorry this is so confusing!
Yeah, 'they' could have put a 'spike' on the MMDC data bus.
We had an occurrence very similar to the Bus on the Freightliner chassis mentioned above. Started the coach one morning some years ago and odometer acted 'funny'. Did not display correctly, made no difference if switched between trip odometer and regular one. Turned off ignition the restarted. Odometer now read 52180 miles less than before!
Next time we were at Freightliner service in Gaffney, SC I spoke to the techs about the problem. No fix except to replace the MMDC at a cost of $400.00 back then and get odometer to start at zero. Kept our MMDC. Got Freightliner service manager to sign document explaining discrepancy.
I periodically check the difference between what the odometer reads and the reading found in the Service Section of the Freightliner Information Center. Then you also have the reading from Cummins, in our case, from the engine!!
