Description
The low voltage battery management system (LVBMS) reports the low voltage (LV) battery's internal protection transistor (MOSFET) has opened and it is not recoverable by any device.
Condition
The LVBMS reports to the vehicle controller that the LV battery is not recoverable due to any of the following conditions: depleted LV battery state of charge (SoC) due to deep discharge; one or more cell voltage(s) at less than its threshold; the sum of all cell voltages is less than its threshold.
Clear Condition
The LV battery is replaced and its internal protection transistor (MOSFET) is detected closed.
Potential Impact
The LV battery is not recoverable by any device.
