The low voltage battery management system (LVBMS) has opened the low voltage (LV) battery's internal protection transistor (MOSFET), disconnecting the LV battery from the rest of the vehicle electrical systems.
<0.01% (Extremely rare)
Low voltage battery service is required
Schedule service - Vehicle may not restart
The LV battery is unable to support vehicle electrical systems or to recharge via the power conversion system (PCS). The high voltage (HV) system will remain energized to continue supplying electrical power to the vehicle while the LV battery is unavailable. This may result in greater range loss than expected, increased HV system energy consumption when the vehicle is idle, and prevent the vehicle from sleeping.
The low voltage battery management system (LVBMS) has opened the low voltage (LV) battery's internal protection transistor (MOSFET), disconnecting the LV battery from the rest of the vehicle electrical systems.
The LVBMS reports the LV battery's internal protection transistor (MOSFET) is open.
The LVBMS reports the LV battery's internal protection transistor (MOSFET) is closed again.
