Was bedeutet der Fehlercode?
The infotainment control module (ICM) confirms that the MOST network is closed, which is required for communication to be possible. The code means the network is complete but no communication takes place. The code is generic and does not say what type of fault it is.
Mögliche Ursachen
- Dirt or damage at the connection for the MOST cable
- Open circuit in the MOST cable
- Damaged MOST transceiver in one of the control modules on the network
- A control module on the MOST network has no power supply
- Blown fuse
- Damaged control module on the MOST network
Was Sie tun können
- 1Check that the fuses are intact
- 2Check that the MOST connectors are clean and seated
- 3Look for chafed or pinched sections of the MOST cable between the control modules
- 4Have a workshop with diagnostic equipment check which control modules on the network respond, since a damaged control module or transceiver cannot be seen from outside
- 5Switch the ignition on for a while after the repair and check that the code is not stored again
