ABS light and brake light are on

Check the brake fluid level.

It's full

have the code(s) read and replace the parts if you want , if you don't drive like a maniac you'll never really need ABS , I think I'm in better control if I can lock them up if I have to , it might matter when you want an inspection though

its likely a short in the harness get under the car and check the abs pumps harness. I have seen one other guy have the same issue and his had a burn ot socket.
