Christmas Tree of lights

First two still shots are from the original error of sorts. Normal ass driving in 60 degrees. Nothing stupid, commuter stuff at 40 MPH.

Last is when I shut entire truck off and restarted it.

 

How old is your battery? I've had xmas tree lights in other cars when the battery was on its way out.

 

Original, 2016.

 

You need to scan it to check what codes are present. Toyota vehicle will disable other systems for unrelated codes.

 

I'd say battery, 5 years of New Hampshire weather.
Go to Autozone or similar, they test batteries for free.

 

Tested battery, appeared to be good, but needed charge... Recommended I replace before winter, so I replaced it.

Code was listed as rear LH speed sensor.

I removed it, douched with electrical cleaner/spray. Kept showing same sets of lights/errors, till just now, I go home and no lights were on.

I am cautiously optimistic that it is fixed, but we will give it a day of driving tomorrow.

 

Well, I applied two solutions and it ain't clear what solved it. No error codes today. Either new battery or electrical connect cleaner to the speed sensor. I'm leaning towards new battery.

 

And it is back... apparently I need a professional look.

 

Can you access the data stream with the scanner you have?

 

Wondering if maybe a mouse got to your wiring somewhere ?
