Hi Scotty,
I have been your fan for years. The 2012 Toyota Camry has three lights on at the same time (ABS, Brake and Traction Control). There is no change in drivability. Just annoying that light turn on and off on their own intermittently. Please let me know what is your observation. Thank you.

Have your vehicle scanned with a diagnostic tool
You need a higher level scan tool to be able to read the ABS codes and act accordingly.
This is a VERY common thing on Toyota products and a snap to fix. It's the vented gas cap. Seriously, look it up on Google like I did, that is how I found the fix. Buy a new fuel tank cap for your car - I suggest getting a good one, not the cheapest Chinese one - have those codes cleared and they will not return. My 2005 Lexus did exactly the same thing, out of the blue, and I thought "oh geez that's all I need..." Did some research, the gas cap fixed it, been good for two months so far since. Why the gas cap would set off those lights, I don't know, maybe someone said online and I forgot, but that IS the problem.
Google the issue and you'll see countless posts with people having that same problem. Gas cap fixes it!
