you need to check the brake light switch, which is located under the dash, just above the brake pedal rod.. when you step on the brake pedal there is a spring loaded switch just above it that is allowed to expand, thus making an electrical connection and energizing the brake lights.

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.

brake in a car is verry important for your saffety and others. that why they install many devices or systems to control them and make shure they work propely 1; brake light switch on the pedal floor(to indicate to the folowing car that you are stoping) 2;brake sensor fluid level (on the brake master cylinder under the hood)
to monitor the level of the fluid in the reservoir 3; brake pressure sensor (on the brake dispencer under hood) will warn you in case of brake pressure faillure .note, it may be more sensors, depending on the make of the vehicle but this is the tree comon causes for brake ligth to stay "on"

get a manuel from an auto parts store. in this manuel it will have etm(electrical troubleshooting manuel) it shows the brake lights and wires colors of wires. trace the wire color from the fuse using the diagram. purchase a test light from wal mart to see if your wire has power. if it does there may be a bad connection or component but hte etm shoud show you what components are on the circuit.any questions email me at [email protected]

Check the break light switch, it's under the dash on the brake pedal, it's made of plastic and screws in you will find the plasitc threads stripped it will have 2 or 3 wires running to the switch. It will have a half inch lock nut that holds it in place. Hope this helps.
