I've got a 2010 Ram 3500 showing 999,999 kms on the dash. The gentleman I purchased the truck from used it for hot shot trucking, and suggested it had 1.2-1.3m kms. Does the ECM or another module on the truck record the real mileage once it exceeds 1 million? Was hoping to be able to read it with a scan tool so I can keep track of the mileage on parts I install. I'm also curious how far the truck has been driven.

Thanks!
Mike

WOW, dunno, but I have a friend that has a 2006 Toyota Corolla, and he had to get another dash unit for his car as it quit working (odometer), at 300,000 miles. MY only thought is: cannot you not hit a button and turn on Miles display instead, so U be at 621,000 and change miles if U find no resolution to your problem?

ADDED: Read on Cummins forum: The meter will stop at 999,999 or miles equivalent. There was no one who chimed in on any way to reset, at least you are not supposed to be able to reset odometer. THE only option offered was to go like to a junk yard and replace that whole unit.

2nd OPTION: Contact this company and see if they can help you/? Only other thing I found.

I had wondered about changing the cluster to miles. The older trucks don't have an infotainment unit the newer ones with uconnect where you can change from metric to imperial units through the radio. There is a separate adjustment you can do with the cluster menus to change some units to imperial (like temperature).

I was digging around a bit to see if I could find how to change the odo to miles when you've got an oldschool radio with no display, but I've had no luck so far. Figuring a way to make it show miles is probably the easiest way as surely it's gotta be way under 999,999 miles (I hope haha)

--Edit - Just checked and when you change the cluster units to imperial, the trip meters do change to miles, but not the odometer itself.

NOPE: They stop at the Miles equivalent as reported by others on Cummins forum,. SO unless you can possibly send to the TV NAV and go guy to reprogram, or go and replace with another cluster unit from say a junkyard (dread to think of wat a new one cost if even available), me thinks U R stuck, unfortunately, IMHO. The web site is under MX but there is a phone number, sorry, all the info I found.

You're right. They actually stop working at the 621k miles even on US trucks. Wouldn't have thought that haha. Apparently the mileage is actually stored in KM on all of these trucks, and the miles value shown on US market trucks is a calculated value from the native mileage stored in KMs.

The true distance the truck has travelled will forever be a mystery.

ECU records actual mileage regardless of odometer read out. I dunno ref odometer om=n miles stopping at 621K but makes sense, but I have never ran anything up to more than 150K miles in any vehicle I have ever owned. The OTR truckers and such would have those monster miles/KM's.

My (driveway princess) at 4 YOA sitting at under 20,000 miles.

Maybe you can set a trip ODO to zero, and let that count up, don't reset it again. At least you can see your distance travelled going forward.

On my 2013 the mileage is stored in multiple places, definitely the cluster (doh!) and the PCM. Don't remember exactly but I think some other modules (BCM ?) have a copy as well. However they all might have the same limitation, if you have alfaOBD or know somebody who has it would be easy to confirm.

The trip meters don't work anymore, because the odo isn't changing lol. Trip a and b are both at zero and driving does nothing to change that :(

Might see if I can get an Autel tool or something to check. I've tried with an odb2 codereader I have, but it doesn't allow you to access mileage information.

For ***** and giggles, I checked the engine hours - 14,549.

It seems like most folks hover between 200-300 hours per 10,000 miles or 16,000 kms with these 6.7s. Knowing that this was used for hot shot trucking, I'm thinking it's probably on the lower end given the high highway mile usage. That said, there was probably high idle time as well as the previous owner did sleep in the back of the truck I'm pretty sure (rear interior was gutted when I got it).

Let's guess 220 engine hours per 10,000 miles/16,000 km.

661k miles or 1,058,000 kms.

That seems to line up a suspiciously close to the static mileage number. I'll have to confirm the engine hours are actually moving, and haven't frozen like the mileage has...

Wonder if my Lifetime Warranty would "fix" this if I ever get there? :) Technically, something stopped working.

I'm sure they would argue that the value of the vehicle is less than the cost of the repair. They would end up buying out of the contract.

There are speedometer/cluster repair outfits. Contact a couple and see what they can do. Here are a couple examples (of many):


There are some OBD-port "Odometer Correction Tools" available. You might see if there's one that works for your RAM and if someone locally has one. Or if it's worth buying one. I haven't used one so I can't claim how they work. Contact the mfgr. There are several out there.

Buying a used low-mile vehicle will never be the same!


There seem to be several out there, so read the reviews. I haven't personally used any, but I know they exist. The OP might be in a small group who may need to try it first and report how it works.

Contact Stellantis. I'd say a 1M km Ram is worth starring in a commercial and a new, free truck.

Love it!!

...and if that doesn't work, start storm-chasing!!
