What does this fault code mean?
The telephone module (PHM) and the infotainment head unit (IHU) communicate with each other over USB. The fault is stored when communication on the bus to the head unit is lost, even though the USB link is established. The mobile phone and Volvo On Call can then have problems.
Possible causes
- The head unit or the telephone module may hold wrong software
What you can do
- 1Check the fuses in the fuse box. Their locations are shown in the owner's manual or on the cover of the box
- 2Check that the USB connector and the cable between the phone and the car's system are firmly seated and undamaged
- 3Clear the code and road test the car. If it returns, a workshop should check the software in the head unit and in the telephone module
