Was bedeutet der Fehlercode?
The serial number of the integrated audio module (IAM) is kept in the CEM and compared at start-up. If the IAM is not on the approved list, the Infotainment Theft Protection (ITP) function blocks it, and the radio and CD player stop working. The code is set when the infotainment control module (ICM) registers this mismatch.
Mögliche Ursachen
- Fitting an integrated audio module that the CEM list does not approve
- Software not loaded when the audio module was changed
- 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 integrated audio module was recently changed, check that software was loaded with the change. The download is done by a workshop
- 3With a diagnostic tool, read the fault code after switching the ignition on, clear it and see whether it returns
- 4If the fault remains after the software download, the integrated audio module may need replacing. A workshop should assess this and check that the unit is accepted by the system
Symptome, die Sie bemerken können2
