My ABS, Brake Light, Traction Control lights all come on and stay on while driving. However, if I drive approx 30kms (20-miles), stop, turn my car off and then back on again, the lights will come on when I start the car but will then turn off after I drive the car about 20-feet. They will then stay off if I continuously drive or shut the car off for short periods of no more than about 45-mins. If I let the car sit for more than about an hour or so, the lights come on again when I start and drive and will continue to stay on until I drive a while and do the whole turn off/start and drive procedure once again. Braking does not seem to be affected as even though the ABS light is on, the ABS does actually work. This is driving me nuts!!

 

All those systems and warning lamps use input from wheel speed sensors. Since this is an ongoing condition, if you can get to a place with a scanner that can read BCM codes(not just OBD11 engine codes), they are very specific as to what problem the module is seeing and will be stored in memory even when you get the light to go out as you do. ANYTHING else suggested to do here is mere SPECULATION.
