Was bedeutet der Fehlercode?

Although the code is named internal software, it applies to the control module's configuration ID on the CAN network. The infotainment control module (ICM) compares its own ID with the signal configuration that the central electronic module (CEM) sends out. If they differ, the code is stored. The control module then switches off its CAN communication.

Mögliche Ursachen

Incorrect configuration ID, for example a used control module from another car with different software or hardware
Break in the CAN wiring to the central electronic module (CEM)

Was Sie tun können

1Has the control module recently been replaced with a used one? Have a workshop check that it is intended for this car and that the right software is loaded
2Check that the connectors in the CAN cables between the infotainment control module and the central electronic module are seated and free from corrosion
3Use a multimeter to check that the CAN cables have no open circuit, and twist and move the cables while measuring
4Do not replace the central electronic module for a CAN fault unless troubleshooting has shown that it is faulty
5Clear the code and switch the ignition on for a while to check that it is not stored again

Symptome, die Sie bemerken können2

Infotainment functions do not work
On S80 (07-), V70 (08-) and XC70 (08-) built before late August 2008: the audio unit, the audio unit display or the radio does not work

Was der Fehler beeinflussen kann2

The control module switches off its CAN communication (bus-off)
The control module still responds to the diagnostic tool while the code is stored
