Co oznacza ten kod błędu?
The fault is intermittent, meaning it is sporadic. The phone module (PHM) registers that the signal from the phone box to the hands-free speaker is short-circuited to ground, so the hands-free function does not work. The fault may be gone when you check the car.
Możliwe przyczyny
