Was bedeutet der Fehlercode?
The head unit (IHU) monitors the signal wire to antenna amplifier 1, which serves the window antenna for AM/FM1. The code is stored when the voltage on the signal wire is too low, which points to a short-circuit to ground between the head unit and the amplifier.
Mögliche Ursachen
- The signal wire between the head unit and the amplifier is short-circuited to ground
