My WTF last 24hrs....all warnings lights flashing

Your settings reset. The truck learns and adjusts that mileage over time. You have a bad battery is my guess.

My .02 is to get a new battery and monitor the situation

 

FYI......I popped in a new battery thinking " Please gawd...yes.....please work and reset!" NOPE...same old light show on the cluster.

 

I know for most folks who get the Christmas tree it is a low voltage issue attributed to the battery.

Sorry it wasn't that easy of a fix for your truck.

 

Any chance you are running larger tires and recalibrated with a Hypertec? My 2015 did the exact same thing yours is when the unit crapped out.

If not then I would bet its somewhere between the computer and your gauges. Probably also the reason you aren't getting any codes as the computer doesn't see that.

 

Tires are same as stock. No lift, no alterations at all. I'm thinking more and more...wiring harness frayed somewhere.

 

Rodent damage? Is there any shit in your engine bay?

 

Nothing in engine bay after I did a look over. No nesting shit, droppings, grass...etc..... My truck is parked outside all the time . Driven every day.

 

Did you check some of the wiring harnesses and lines under the bed of the truck? Maybe something flew up there and clipped something.

 

Dude...if you DO get 582 miles out of this tank, I'd just deal with the warning lights until gas goes down again

Probably not related at all, but I had something similar happen with my 2011 a couple years ago, every warning light came on at once on the highway one time when it was bitterly cold outside. Nothing seemed amiss with the truck - drove fine and made it where I was going. When I started it back up, everything was normal. It happened one more time like a week or two later, and since then, not at all. It was definitely a WTF moment.

The dealer said it was throwing no codes at all? If so, it definitely seems like a wiring/electrical vs. sensor issue (not saying a sensor can't be broken or potentially on its way out though, but you think that would be a more specific warning, unless the design is to give you ALL THE LIGHTS if there's an issue and the display tells you the specific problem? Have you checked to see if there's any crud/crap/snow/salt in there somewhere? I have seen times when snow buildup in the tires will kick off the traction or ABS sometimes. Not sure how the recent weather is down by you, but my FedEx package earlier this week was delayed in Chicago, apparently due to weather, so I'm guessing something came through (or FedEx is lying, which is equally as plausible).

 

My Buddy had this happen in his 4 Runner. It was the ABS harness going to one of his rear wheels. You couldn’t see any visible damage but he ordered the part and swapped it out and problem solved. He thinks it was pinched going off road or something smacked it pretty good. Just a thought.

 

90% chance it's speed sensor related. Double check it and the wiring.

 

My battery failed a couple weeks ago and after I put the new one in my distance to empty showed 680 miles and my tank was only half full

 

UPDATE. sucks.
Took it a new mechanic. He even put 4 new tires on to see if it changed anything. Nope.
They sent it back to Toyota service center since they all know each other in the city I. Now they are saying it's the right rear hub assembly and its shot or was damaged by a foreign object which is possibly causing the ABS sensor to go nuts therefore causing all the other issues/ lights, warnings. Needless to say they want $1300 to replace the hub...etc. Fucks sake this has cost my company a shit ton already. Toyota.......starting to lose it for me.

 

I would replace the abs/speed sensor before the rear hub assembly. As others have said it can cause havoc to the dash. From parts.toyota.com

 

Yeah, wheel bearing goes bad, tone ring rubs on sensor tip or just don't read correctly anymore. Mechanical wear is gonna happen when moving parts are involved. This is not a terrible DIY job.

 

How many miles on this truck? Sounds premature for a 2019 unless the blowout caused the damage

 

Did anybody check the rear diff oil? Maybe someone backed boats in the water or else drove in too much water and flooded the diff through the vent. Poor lubrication=>premature bearing failure. Just maybe.

 

OK OK>.....finally. The ordeal/saga is over!!
Freaking Toyota better write a white paper on this whole damned thing and post it to all Toyota service centers.
I took it back for a 3rd time to my Toyota dealership and spoke to the service manage and we agreed it has to be something in the bearing, axle...etc.

The culprit: Right rear hub bearing was somehow damaged causing seal failure allowing metal debris to rub or "infect" the nearby ABS sensor. Keep in mind this issue was on the other rear wheel that did not blow out. So new hub and seals were ordered and put on yesterday. Everything went back to normal. No more lights, all sensors, blind side sensor, cruise control , ABS, 4WD, all working.
Thank GEEBUS!!!
Still cost me $520.00 but screw it I need this truck to operate as its supposed.
so far so good.

 

Glad you got it nailed down! Pretty sure I mentioned that sort of condition could cause your issues.

 

WooHoo....am glad that is behind you!!

 

Closure, it's a good thing! Glad the correct problem was found, also glad you didn't spend too much on the repair!

 

So the Christmas Dash Lights of Death were caused by a fubar ABS sensor, which was fubar because of metal debris?

 

As I was waiting on the paperwork after the repair work was done . They had a sweet black 1794 sitting near me. Tan leather, all the bells and whistles. And here I was a few minutes ago saying "fuck Tundras".......I maybe back after all

 

Thanks for the follow-up and closure this will surely help someone in the future!!!!!!!!!!!!!!!!!!!!!!

 

Just reading all this now but as well as I know how this truck communicates between ECUs, wheels sensor ect would have been the first place to go.

I really think if you had one reading improperly it would have shown up in techstream under the Skid Control ECU section. It knew to turn all the warning lights on, it also knew something was wrong. I would be asking my dealer tech how well he actually looked for trouble codes. Techstream is very powerful when used correctly.

 

My battery shit the bed 2 years in, pretty common for toyotas batteries
