Co oznacza ten kod błędu?
The BECM controls and monitors the high voltage battery contactors at the same time and checks that the voltage matches the contact positions. The code is set when there is no voltage in the high voltage circuits even though the negative-side contactor has been commanded closed, which means the contact is stuck open. The fault may be caused by a damaged high voltage battery.
