ABS warning lights on and jolting?

This can happens when one of the wheel speed sensors goes out or the wiring to one of the sensor gets ripped out of the connector by road debris. I would raise the car up to inspect the wiring to each of the sensors. To help find out which sensor it is you can do a ABS scan to see what codes are stored to help pinpoint the issue.
