Weird thing with my 08 Tundra

Driving home in my 2008 tundra, I noticed my vsc light was flashing, my 4hi and 4low lights were flashing, my abs light was flashing, and my traction control light was on…I pulled over right away. I turned the truck off and on again, and all the lights disappeared besides my ABS light. That light stayed on for about 3 more tries of turning it on and off again. Until I drove it to the shop and then the abs light disappeared. I hooked up a cheap code reader and saw no codes. I believe my reader only checks engine codes tho. I’ve noticed lately that when I’m driving at slow speeds and apply the break as I’m hitting a small bump…I feel like a rattle or vibration. Only when I hit a bump just right as I’m breaking. So I’m wondering if that could be linked to what I noticed today with the lights and ABS light coming on?? Anyone heard of this before??

 

Wheel speed sensor

 

Is that a serious fix?
