1st get autozone to clear the code, (free) The only thing I can think of that goes out when car is off and on when lights turn on is the parking lights on the side, the wires could be touching in the conduit, start car and pull brake fuse out, if the lights stay on you have a short, if only the park lights stay on (double filiment) look at the lighting system, but if the brake and driving light stay on, sounds like an ecu problem.
