Hva betyr feilkoden?
Signals from the steering wheel buttons travel to the infotainment head unit (IHU) over the LIN bus. The code is stored when a received message does not match the expected message.
Mulige årsaker
- A fault in the transmitting control module, the one that sends the steering wheel button signals
Hva du kan gjøre
- 1Read and clear the code, then check whether it comes back
- 2Check that the relevant fuses are intact
- 3If there is another code from the same control module that concerns the same LIN bus, work on that one first
- 4If you have a diagnostic tool: read the steering wheel button status in live data while you press the buttons
- 5If the fault remains, have a workshop trace the LIN bus further
Symptomer du kan merke1
- The steering wheel button panel for audio does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
