I understand that our trucks have a counter that count the time that the truck idles. I have done some searching, but I cant figure out how to bring up that feature on the odometer.

Another question is this, does the "hour meter" count the time the truck idles if it is in neutral???

 

If you push and hold the odometer button in for 5 seconds it will display the hours on the engine.

Key must be in and on the last click before starting engine.

Not sure the what the breakpoint is for minimum hours vs. miles traveled though?

1068 hrs

28431 miles

So my lifetime average is 26.620786mph

Anyone know the minimum mph is that Cummins/Dodge set.

 

You have a hour meter that you can bring up.It keeps track of TOTAL RUN HOURS.Now you know that the hours are not like a actual hours on a watch.Differant RPM dictate how fast hours are recorded. Idle time which is under 1000 rpm ,I assume can be retrived with a DRB or Star Scan tool(scanner) To see actual run hours push stalk for odometer I think engine off,key on and HOLD in until engine hours appear.Takes 30 seconds or so.Been a LONG time since I played with that feature.Someone else might chime in now.Owners manual should explain this feature.Also use the SEARCH function provided.Lots of info in archives.

 

According to Cummins less than 35 mph average speed is considered severe duty cycle. Dodge does not sell the Cummins in these trucks as a severe duty application. Therefore you are in violation of intended use and you warranty is void. So sorry.

 

Where did you get this info? I would like to read it.

 

I was told by the dealership that the computer stores it as a idle hour traveling under 1200 rpm for extended amount of time. Don't know how much my info is worth, but I keep mine in tow/haul mode around town to keep RPMS up and so far been working.

 

Well, that would put all the farmers hauling hay and cattle on our twisty, hilly roads in violation. So far, I haven't heard of anyone local being denied warranty for going the speed limit.

Now, if Dodge said excessive time spent at low RPMs, instead of below 35 MPH, that might make some sense.

 

So just about everyone who lives in California should have voided warranties.

I recall reading that Cummins doesn't follow hours or miles for rebuilds, Dodge is responsible for those numbers. Cummins says if you burn a quart of oil in 10hrs or 400 miles, it's time for a rebuild.

 

NO-6... I question what you are saying, I have 88,824 at 44.7 miles average. Knowing that I cover most of my miles on the freeway and not in town, I find it hard to imagine that the average driver would get to 35mph average, if it was for normal personal ownership. Heck, I think I live on the freeway. Am I missing something? (Would not be the first time) Are there people who use their truck as a daily driver and have over 35 mph average? at the 1984 hours I have to average 35.24 you would still have to put 70,000 miles on the clock.

 

My truck is a daily driver and last I checked my average is 35.38 mph with 46k miles. I have been averaging 20k with this truck. My past vehicles have been averaging 15k per year, this truck must be more fun to drive .

 

My average is 41.6 MPH

I'm not sure the engine hour clock measures time in anything other than actual hours.

Otherwise the averages would likely be higher, I don't think it is like some tractors which would measure hours at rated PTO speed, therefore logging fewer hours than actual run time. John Deere tractors have always been famous for clocking many MORE hours than actual run time.

 

Well, I wondered what I was going to do this morning and then I found this thread, SO ...... I went out and checked my trucks' hours and mileage and it came out to: 24,034 miles and 723 hours for an average of 33.24 miles per hour.
To me, it's pretty hard to call 'less than 35 avg. MPH Severe Service' unless the actual RPMs are factored in. For example if you are in 5th at 12 or 1300 RPM it's way different for the engine than say, 18 or 1900 in 4th at the same MPH .... I keep mine at 1600 or better when at all possible which is except for stopping/starting.
Anyways, thanks for giving my grey matter a jump-start!

 

19981mi, 600 hrs 33.3 mph. I have always been under 35, just a little.

 

DC does frown on excessive idle time. The ECU tracks that as time less than 1200 rpms.

Cummins says less than 35 mph average speed is SEVER DUTY and you must maintain different a different maintenance schedule. However, DC does not sell these trucks for a severe duty application. This has been a sticking point on idle times since the CR engine was introduced and can be used as a basis to deny warranty. Its been done so......

The ONLY way to get an average speed is miles\hours, and, its really the only thing thats makes sense when you have an engine that does not spend the bulk of its time at a rated rpm. Cummins uses this criteria for the different applications of the engines to determine warranty and maintenance. DC just picked one piece to use as cutoff point.

Will your warranty automaticaly be denied for avg less than 35 mph? Probably not if they can find something else to blame. Depends on the dealer and regional rep and how they view things.

 

Only know what I read and I read time after time IDLE TIME was 1000 rpm or less.I've never known a hour meter on a vehicle to follow actual RUN TIME.My two tractors don't.The HIGHER the rpm the FASTER the hour meter.
