Electronics Megane II Anomaly

Hello everyone, I have a Megane II Phase 2 2008, yesterday the message "Electronic anomaly" has presented me Finish the check, gave an anomaly to see with the switch of the brake lights but these are worked ok. I left the workshop without the message and the light off but nothing like the last time it turned on after a while, I could no longer return to the workshop because they come out of Christmas vacation, the curious thing is that I disregard the problem, so as not to worry and the same day the light went out alone and the message disappeared.

Someone has an idea of ​​the problem or someone has happened to someone

the battery this new

greetings and Merry Christmas

If the scanner gave the brake switch as a failure, since it is cheap and can solve the problem. Normally these switches are double, that is, a circuit for light and another for injection. One may work and another does not. All the best

Thank you for your response deiviz6, I am risking to change it is true is cheap and easy to replace,
