(RESOLVED, T-SB-0148-16) Uninitiated trip meters reset

I too had my Combo meter replaced under the TSB in 2016. No random resets since. I am on my second battery and honestly don't remember if it reset when I had to jump start it. At the time, I was more concerned about having the truck reliably start than what the Combo meter said.

 

Mine reset when I replaced the battery even though they used the 12V power device to keep the truck “alive” but the last few weeks has been the first time since then. I hope my battery isn’t dying again. The OEM battery lasted about 3-1/2 years but this aftermarket battery is only 2-1/2 years old.

 

I noticed my trip meter reset on the way to Utah parked either in green river or farmington nm, and the trip reset to 0, but sat in lehi for 3 days and stayed with me since for over 2k miles.

 

Well my truck is now experiencing this issue. I’m going to get my battery tested but I just got a replacement 3 months ago. Think they will honor a truck with 76k miles?

 

I had a strange one... while highway cruising, my old lady turned around to feed the kids a snack (kind of like twisting herself backwards between the front seats).. In that moment the airbag light, seatbelt light came on the dash, along with the "passenger airbag off" light, AND a trip meter reset (trips A and B). Has anyone has an airbag light come on associated with an uninitiated trip reset? Definitely had nothing to do with the battery as we were cruising. Airbag light has stayed on, going to the dealer tomorrow. The trip meter reset at the same time can't be coincidence...

The truck did have 2-3 uninitiate trip resets in the past, always during starting in extreme cold though.

 

I've been having this issue very intermittently since I bought my truck in 2020 from the dealer. It was a 2016 that was traded in with 50,000km on it at the time. Sometimes I can get 5000km or more before it resets. Sometimes it happens weekly.

Might be a stupid question but is the TSB a recall thing where I don't have to pay for it? Or is it a warrenty thing where I'm only covered within a certain time frame or milage since purchased? I did get a warranty of sorts when I bought the truck. If it's something that I have to pay for I will likely just suck it up as it isn't a huge inconvenience.

Alternatively, is there any way I can fix it on my own?

 

Check out post #350 for a copy of the TSB. Looks like the repair is covered under the Toyota 3 year warranty period. I had my Combo meter replaced in 2016. Dealer had to order the new Combo meter with my exact mileage so there is no ODO issue when I sell it. The link below will make it easier for you to find post #350.

This just started happening this week with my 2017 TRD Sport. I was starting to wonder if perhaps I need a new battery as it has occurred twice this week since our weather has gotten cold, below freezing and snow this week. Happened Monday and again this morning. Truck only has a little over 20k miles on it. Bought CPO in 2020. Any chance I'm still covered?

 

Its the battery, time to replace it.

 

As the starter of this thread way back when obviously I had my meter replaced and I haven't had my trip meters reset after the replacement until starting the truck first thing yesterday morning. And then again this morning, but not when I first started the truck this morning, it was after driving 2miles to the gym at 05:30 and then it sitting for about two hours. Yesterday morning's low temp was in the upper 20's, not quite the lowest of the year, and then this morning was low 20's, the lowest of the year. I moved to NM from AZ over the summer so my truck hasn't seen a lot of temps in the 20's. At about 76k miles now so haven't had a reset in over 50k miles I am guessing. 9 year old truck. On my 2nd battery. I did start thinking a couple of weeks ago that my truck was ever so slightly starting to take a bit more cranking to start. I am still under warranty as I got a 10year/100k warranty given to me due to all the issues I had after purchasing, but it seems like replacing the battery might be the first step in determining if my meter has gone to shit or if the voltage is just dropping to low during start up and killing the temp memory features. I guess if one was aware enough they could turn the ACC on without starting the engine and check the trip meters to see if they are still accurate before cranking the engine.

 

Let us know your outcome. Thanks again for starting this thread. I had to show my dealer the TSB in post #350 (back in 2016) because they said they never heard of the Combo Meter TSB.

 

I have not had anymore resests after replacing my battery.

 

My toyota battery on my 2017 is about 3-4 years old (This is the 2nd one---original was replaced under warranty), its been crazy cold here lately in the midwest -20 degrees. I just noticed on my drive in to work this morning my trip was reset, I've never seen this happen before and I haven't had any issues with it showing signs of a weak battery but this might be a sign its on its way out. I'll likely just swap it with an AGM just for peace of mind this week.
