Co oznacza ten kod błędu?
The infotainment head unit (IHU) has detected that the fibre-optic data ring (MOST) is not closed. Audio, radio, navigation and phone communicate in a ring where each unit passes the signal on, so a break anywhere in the ring takes the whole system down.
Możliwe przyczyny
- Dirt or damage in a fibre-optic connector
- Broken or sharply bent fibre-optic cable
- A unit in the ring has no power supply, for example due to a blown fuse
- Fault in one of the units in the ring
Co możesz zrobić
- 1Check the fuses for all infotainment units
- 2Find out whether any audio or infotainment unit has recently been fitted, replaced or disconnected
- 3Check that fibre-optic connectors are fully engaged and the cables are not pinched or sharply bent
- 4With diagnostic equipment locate the unit that breaks the ring
Objawy, które możesz zauważyć1
- Audio, radio, navigation and phone do not work
