BEGIN OF REPAIR PROCESS - STEPS
 1- First, troubleshoot and confirm that you have encountered errors from the list retrieved via the diagnostic OBD tool. These errors can lead to a permanent lock of the Battery Management System (BMS) if DCDC was on fire or shorted and then BMS will need repair to. This repair covers those DCDC errors and in some cases DCDC is not repairable. However, once unlocked operation manual is not refundable. In 50% cases it is mostly software defect and repair is easy, but in other cases there is HW and SW defect and repair is complex and deep troubleshooting on the bench is needed
 First step is to place DCDC inverter into DCDCBOX device to confirm you got same problem on the bench with 12V battery connected to simulated output
 Now connect 300V-400V powersupply with more than 1 Amp available power to the backside of DCDCBox. (It will work even on lower voltage 240V)
