Hva betyr feilkoden?
Too little voltage reaches the carphone box, and the fault is intermittent, so it may come and go. The code is set once a supply fault has been picked up by the keypad unit or carphone control module (PHM). If the code does not come back, no further action is needed.
Mulige årsaker
