im looking at a 99 2500 that supposedly has 59k miles on it. the guy says he bought it 1 year ago with 34k on it. can i get the odometer checked to see if it has been unplugged or messed with? does a dealer have something they can plug into the computer and tell me????

I think the Cummins ECM has some memory but I'm not sure whether or not it shows milage.<br>BTW my '99 only has 38,000 miles on it. (barely broke in, huh [laugh])

Hmmm, interesting question PK. Let us know what you find out.<br><br>I know that all you have to do is pull out one two spade fuse out of certain GM products. ::)<br>to kill the speedo and the odometer.

The ECM will show engine hours.
