Was bedeutet der Fehlercode?

ICM tests whether the MMM appears on the approved list held in the CEM. If the serial number does not match, the MMM is blocked and the navigation function is lost. Although the code is labelled navigation control module, it is the multimedia module that is checked. The code is set when the mismatch is detected.

Mögliche Ursachen

Replacement with a multimedia module that the CEM list does not approve
Software not loaded when the multimedia module was replaced
The software download failed or was incomplete

Was Sie tun können

1Check that the fuses are intact. Their locations are given in the owner's manual or on the fuse box cover
2If the multimedia module was recently replaced, check that software was loaded. The download is done by a workshop
3Check that the connectors to the multimedia module are firmly seated and free from oxidation
4If the fault remains after the software download, the multimedia module may need replacing. A workshop should assess this
