Hva betyr feilkoden?
The head unit (IHU) measures the voltage on the signal wires to the AUX output. The code is stored when the signal wire has too low a voltage, which is a sign of a short-circuit to ground.
Mulige årsaker
- The signal wire is short-circuited to ground
Hva du kan gjøre
- 1Clear the code and check whether it returns while nothing is connected to the AUX input
- 2Check that the fuses are intact
- 3Disconnect the accessory from the AUX input and see whether the code clears
- 4Check the AUX cable's connectors and the cable itself for damage, especially at the ends
- 5If the fault remains, have a workshop trace the AUX output and the wiring further
Symptomer du kan merke1
- The AUX panel does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
