Hva betyr feilkoden?
This code only needs to be investigated and repaired if it is active in the current drive cycle, has been active for a long time and you are experiencing a loss of function. The audio module compares its system voltage with the one in the central electronic module, and a supply fault can set the code with the ignition on. In other cases the code should be ignored and cleared.
