Hey you may want to make sure all your brakes are properly off. If you leave the E brake on and drive teh car they light will go on. Therefor the ABS turns itself off because something was acting on it (The E Brake being on). SO basically you want to check and make sure all your brakes are properly put on. Maybe make sure your e brake inst to tight and maybe loosen it a little bit.
These are just some ideas before you shell out 1400 bucks.
Hope i was of some help
