 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.
