Your car is equipped with what are called wheel speed sensors which monitor the speed of the wheels at all four corners. When they detect that wheel speed is out of the ordinary in a given set of conditions, this information is relayed to the car's computer which then engages the ABS system or the traction control system. Occasionally, these sensors will go bad causing them to send inaccurate information to the ECU causing the lights to come on intermittently or when not needed. I would recommend having an expert from YourMechanic come to your home to diagnose and possibly replace your wheel speed sensors.
