My car is shaking and feels like the brakes lock up, which then causes shaking of the car and the traction control light goes on and blinks while this is happening. What can be causing this ?

Today while i was driving a signal "service traction control" appeared in th einstrument panel followed by the engine symbol a few minutes later. Is it likely they are related?
Thank you
