Repair operation steps

 1- First, troubleshoot and confirm that you have encountered errors from the list retrieved via the diagnostic Xentry tool. These errors can lead to a permanent lock of the Battery Management System (BMS), even after necessary repairs are made to the battery pack. In certain instances, such as when cells are deteriorated, leaked, or experiencing increased resistance in one cell, or if any other issue is present in the battery, attempts to reuse the battery pack will be futile because the BMS controller is indefinitely locked and requires a battery change as requested by OEM workshops. However, with our solution, you can repair the cell/pack and reprogram the BMS for reuse
