BEGIN OF REPAIR PROCESS - STEPS

However, with our solution, you can repair the cell/pack and reprogram the BMS for reuse. In all cases mostly there is no cell damage, only BMS programmed defect due deep discharge
First step is to make diagnostic error reading from "Auxiliary Module" and print error codes. Then open driver side both doors and motor hood. Then disconnect 12V battery
