Advice-2017 ABS, 4x4 and Blind Spot monitor failure

Hey folks.

Having an electrical issue that nearly forced me to ditch this truck on the way home in a snow storm a bit ago.

ABS not working and a failure notice when you turn the 4X4 switch. Blind spot sensors not working either.

I ordered new left and right ABS sensors and installed them.
Nothing. I moved the original fronts to the back and still nothing.

What do I need for the truck to tell me what the issue is? A computer? Out of warranty.

Appreciate any insight you have. Save that, I will book an app with Toyota in a few days.
Thanks!!

 

Did you figure out what was causing this? I turned on my truck this AM and had the same thing happen. I can't get it hooked to OBD2 until next week.

Hopefully it's all fixed now for you!
