What does this fault code mean?
The telephone module (PHM) and the head unit in the infotainment system exchange data over USB. The fault is stored when no data or audio communication takes place between them, even though the head unit is switched on and the picture shows on the screen. The fault comes from a software or hardware fault in the module.
Possible causes
- Software fault in the control module
- Hardware fault
What you can do
