What does BMS_f107 mean?

Tesla fault code in the Battery Management System (BMS) module. A high voltage (HV) battery cell voltage sensor error is detected. There are three reasons for this alert to be reported by the Battery Management System (BMS): BMS_a107_errorType = BMS_A107_MODULEBRICK_MISMATCHThis alerts means that the voltage of the module differs by more than 35mV from the sum of the brick voltages of that module.BMS_a107_errorType = BMS_A107_TVSH_BLEEDV_LOWThis alert type means that the bleed resistor is turned on for that brick, but the voltage is too low (likely due to a stuck bleed resistor).BMS_a107_errorType = BMS_A107_TVSH_IMP_HIGH This alert type is the most common. The system has detected a high impedance on the sensor harness from the Battery Monitoring Board (BMB) to the bricks / module. It means that the measurements from that BMB cannot be trusted.
