Was bedeutet der Fehlercode?
The control module has recorded an internal fault in its own knock control circuit, so the fault is not in any sensor or in the wiring. It may be a single occurrence or a fault that is still present. The engine warning lamp may come on, and ignition timing is pulled back to protect the engine until the control module is repaired.
