Was bedeutet der Fehlercode?

ICM checks the traffic message channel module (TMC) against the register of approved units in the CEM. If TMC is missing from the register, the module is blocked and traffic information stops being shown or updated. The code is set on detection, usually after a replacement where the software was not downloaded.

Mögliche Ursachen

A traffic message channel module the CEM register does not approve
Software not downloaded when the traffic message channel module was replaced
The software download failed or was incomplete

Was Sie tun können

1Clear the code and test-drive the car to see whether it returns
2If the TMC module was recently replaced, check that software was downloaded. The download is done by a workshop
3Check that the connectors to the TMC module are fully seated and not corroded
4If the fault remains after the software download, the module may need replacing. A workshop should do this
