Could be a failed wheelspeed sensor, could be a failed accelerometer, could be a failed ABS modulator, could be a failed connection to the engine computer. It needs to be scanned by a tool that can read ABS codes as well as OBD2 codes. That’s the place to start.

It could be something as simple as a faulty brake lamp switch

Some auto parts stores will read your abs codes for you for free

If you find one that does this, please report the code to us
