Do your brake lights work? That code indicates a short in the brake light switch (which is mounted to the brake pedal). The most likely problem is the switch itself.

Yeah,lights are working,nothing special to see.I could pull out the connector and then again back to try and see what happend.I replaced yesterday my braking bulbs with smd led bulbs.May this be a cause or not.Tell me your opinion Scott.

With the European ECM, the ECM is connected to the feed to the bulbs on the inside of the switch (so it always sees the presence of the bulb, even when the brake pedal is not depressed). To use the LED brake bulbs you will probably need to use the load resistor, like what is required to use LED turn signal bulbs, with the OEM flasher relay.
