Was bedeutet der Fehlercode?
The code is stored when the high voltage generator control module (IGM) has internal communication that is disturbed or missing. Although the code is named private communication network, it therefore concerns the control module's own communication. The fault is only checked once the test has started at ignition on.
Mögliche Ursachen
- Software fault in the IGM
- Internal fault inside the ISC voltage converter

- 1Read out, clear the code and start the car to see whether it comes back
