The low traction light comes on sometime or just the low.

Sometimes when just the low part of the light is on, when I turn off it goes off. When both the low traction lights are on, I turn the car off and restart it and no lights. I have read a low brake fluid can cause it but I checked it. I replaced the rear calipers and brake pads and replace the front brake pads. I still have brakes and braking ability, but can't afford to take it in so I am trying to solve it.
