Checking The Component

The infotainment control module (ICM) has registered that the Multimedia Module (MMM) is not approved according to the list stored in the central electronic module (CEM).

The cause of the fault is probably that software has not been downloaded or that the download failed when replacing the multimedia module (MMM).

HINT: When downloading software after replacing a control module in the infotainment system, the serial number is stored in the central electronic module (CEM). This is so that the security on MOST function can approve the control module in the MOST network in the car. 

If the fault remains after the software is downloaded, try replacing the multimedia module (MMM).

Remedy as necessary.
