ABS AND ESP Lights

Does anyone know why the ABS and ESP would turn on and off while driving. It just started this morning. When i turn off the car and turn it back on the light don't turn on. But when i start driving and hit any bump the lights turn on.Can the ABS module be going bad?

Could have a loose connection to one of your wheel speed sensors. If one of those wheel speed sensors open circuits, will disable ABS and ESP.
