Open circuit, perhaps. The temp sensor for the outside temp should be behind the grille. See if it is disconnected, or replace the sensor. I am not certain, but does the mirror have a compass as well? Does the compass work? The 'OC' could have something to do with compass calibration. When did the error code appear?
