Idle/Drive Ratio

Even if you could zero out the idle hours on the dash, all this information is stored in the ECM. On many heavy and medium duty trucks, this info is not shown on the trucks gauges so our technicians have to plug into the ECM using Cummins Insite software on their laptops to gather this data for warranty.

Or more succinctly, a bunch of people saying stuff they are totally ignorant or misinformed on.

But never let a good question go to waste without interjecting some unreasonable nonsense to turn it into another "look how much I don't know" thread...

Say wut?
Ummm, no you can’t “zero out” engine hours…..
Lol.
Where would you even come up with something like this?

Well you say they don't track hours well. I would think Ram would create a recall for something to fix an issue like that to prevent warranty fraud!

Can't think of a single passenger vehicle warranty that has been based off of engine hours, ever, but ICBW I suppose.

Now, wandering bob "could" have a defect where those hours "can" be reset, but if he does, he obviously doesn't know that is a problem in and of itself and seems to think it is a normal vehicle function.
Or he could be totally confused with the engine hours and the travel timer, or whatever they are called that you can reset and it clocks hours running.

Bought it with 56k on it about 2 weeks ago.

You sure those are correct? 56,000 miles in 365 hours is 153.4 average mph!
Even 736 hours is an average of 76 mph, not realistic.

736 is the idle, not the drive.

Has the computer ever been replaced??
With 365 drive hours and 56,000 miles 56,000 / 365 = 153.42 mph average speed something isn't right.

I already explained the issue. It’s not uncommon for these trucks to read the wrong hours.

No need to clear IMHO. But if you do I guarantee the computer will keep the score!

It still has well over 1000 drive hours. Probably a minimum of around 1400 if it was mostly highway miles.
These trucks are known to have defective hour meters, some of them. And yours is one of them.
