Weird errors all at the same time - Traction control, ABS, 4 HI / 4 LO, BSM, etc...

Watch video for best explanation.

Summary: After some washboard roads all of these errors came on simultaneously. Errors now come and go randomly, and in different combinations. Might go a few weeks without any issues, then a day or two with a combination of the lights.

Sometimes RPMs, Temperature, and Speedometer will not read at all, or read incorrectly.

Seems to be triggered by long drives, or by traction control.

Dealership said they were able to trigger the check engine light, but when they tried to pull codes there were none.

Battery issues is my only guess currently, but dealership said the battery checked out fine when they tested it.

Thanks for the help!

 

Did the dealer check your speed sensors??

 

I don't believe so, I'll ask them to on the next round.

 

You can get underneath and visually inspect them on each hub. All it takes is for one sensor to be damaged to cause the Xmas lights

 

Loose ground somewhere...

as he stated takes only one sensor to light it up..

 

I'll check and report back if speed sensors were the issue.

Thanks folks!

 

Blaaaaaaack....

 

Hey Folks,

Update on this. The Toyota dealership has had it for a week and they still can't figure out what's wrong. Below are the codes I was able to generate.

The dealership swapped the instrument panel (speedometer, odometer, etc.) with another Tundra they had, but they were still able to generate the issue. So it's currently not the speed sensors or the instrument panel.

They think it's maybe related to an aftermarket remote start that was installed, but I bought it with the remote start already, so not sure on that.

Any ideas? Thanks!
