Trip Odometer Resetting Itself

Ok, random issue.

 

I noticed over the last week my Trip A Odometer is resetting the mileage itself. I think this has happened twice. I had never reset the Trip A (roughly 63, 000 miles on the truck), and use the Trip B for tire rotation scheduling (I'm lazy).

 

Just the Trip A, and just the mileage, not the MPG reading. If you manually reset it, don't both the mileage and MPG reset?

 

2015 GMC Sierra 1500.

 

Any ideas?

Sounds like the trip odometer gets stored in 16 bit register.  The max number for that would be 32,767, which is around half of your current total mileage.

It showed the total vehicle mileage until the reset a week ago... 

you know?  I think this happened to me too now that you mentioned it.....Mine reset because I left either A or B going from driving off the lot to track MPG's... Weird

Yup. that's basically what I was doing. Lifetime MPG average on Trip A... I reset Trip B when I put on Toyo R/T 295/70R17s to see how much the fuel economy changed... (.8 MPG BTW)

I never reset my trip A either. Haven't had an issue with the truck, but my Equinox has reset itself when it struggled to start during a recent cold snap. It finally started but the voltage must have been low enough for a reset.

Yes, they both reset when done manually.

2015 Duramax: I reset my Trip A to 0 after refueling. Drove the truck roughly 30 miles, parked it and shut it off. 20 mins later, I jumped in the truck to leave and the trip had jumped back to the roughly 400 miles that it was at before I reset it. I was able to repeat this 3 times that day. Haven't drove it since.

      Clunk when putting truck into drive and reverse.

      By Matt Parker · Posted

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
