Was bedeutet der Fehlercode?

The signal wire to the starter relay is shorted to battery voltage, so the voltage is higher than allowed. The control module sets the code when the voltage stays above a set threshold for a set time. It is checked when the engine starts.

5If the fault remains after these checks, have a workshop investigate the engine control module
