2005 Santa Fe, 3.5l

All, I have the following lights on, on my dash. "TCS OFF" "ABS" "BRAKE"
They all came on at the same time when making a normal turn at an intersection. The car is still operating like normal. It is having NO stopping issues not any other drivability issues.
I have checked the following:

Tone ring (both driver and passenger)....GOOD not broken and not dirty!
ABS fuses(2 under hood)....GOOD
Brake switch under dash (tested with my ohm meter)...GOOD
Brake fluid...GOOD
Any other suggestions?

 

Did you test the wheel sensors?

 

Here is the update. I tested the wheel sensors today. The OHM test reads 1.305 on both wheels and the AC voltage test while turning the wheel went up the faster I turned the wheel.
I cleaned each of the wheel sensors (there are only 2 in the front).
I disconnected the battery for about 15 minutes to see if that would work.
I checked the brakes on all 4 wheels to see if maybe it just needed pads. (NOPE) .
All 3 lights, (TCS, ABS, BRAKE) all come on as soon as you start the car and never go off. I would think that the ABS light would go off when the car is started and then come on as needed if the tone rings were bad (which I checked again and they are not cracked or dirty)
I guess I will have to find a computer that can read ABS codes. The one at the parts store wouldnt do it.
