Co oznacza ten kod błędu?
Although the code is named signal too low for communication with the carphone box, it applies to the handset loudspeaker signal being short-circuited to ground. The signal runs between the carphone box and the keypad unit or carphone control module. The fault is intermittent, so it may come and go, and the hands-free function then stops working.
