Dash Lights lit up... NEED HELP!

Alright brethren... I need some help. There's been a post or 2 about this issue but from what I've seen, there's no distinct fix or actual issue that can be fixed that's tied to this issue.

I've got a 2015 tundra SR5 4x4.
Here's my issues
1. Tire pressure sensor is blinking
2. 4HI and 4LO are blinking
3. ABS is on
4. Stability control on

This happened out of nowhere. I reversed into a parking spot and when I hopped back in my truck, I saw these all lit up. Obviously the conditions for all these to be on have not been met.

Should I unhook the battery and try to reset? Help me out... thanks yall!

If you're a Toyota mechanic, shoot me a text if you have a fix. 806-476-8261

 

Check your battery voltage. Could have dropped below 12v

 

Could it be a bad wheel/speed sensor?

 

Good call Tony. Didn't think about that. I'll check in a sec. What I did notice is if I turn on "tow haul" it registers just fine. But I was sitting parked ofcourse. Lemme give it a look. Thanks brotha.

 

Do you think a bad wheel sensor could cause all that? I have one "bad" sensor.... only because I had my tire changed around 3 years ago and didn't replace it with a synced Toyota sensor. Just a normal tire valve. But that was moons ago! Thanks Jim... I'll definitely need to have another one put on soon so all 4 are acting normal!

 

Not the TPMS sensor, the speed sensor behind the rotors on each wheel.
Have you gone off road or run anything big over?

 

I was jacking with my relays the other day and pulled the stop/tail (I think that’s the one, back left relay in the box) and when I got in the truck later this is what my dash looked like:


I think your issue might be different, and sounds like it might be an ABS/speed sensor like @TucsonTundra1794 mentioned. It’s worth a shot to disconnect the battery for 10 mins and see what happens. That fixed my issue.

If it ends up being an ABS sensor, it’s an expensive part but I believe it’s pretty easy to install. Check codes if you can.

Rodent damages on wires? Check cabin filter for evidence too.
