Hva betyr feilkoden?
The BECM monitors the contactors of the high voltage battery and how they are controlled. The code is stored when the control of the contactor in the auxiliary circuit (AUX), which includes the charger and the DC/DC converter, gives unexpected current and voltage values and the control circuit has a low level. The fault may be caused by a damaged high voltage battery.
