What would cause these lights to come on?
Is the Check Engine Light also lit up?
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.
No it is not.
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
