The low voltage (LV) battery internal resistance is too high, based on measured voltage being below the acceptable threshold during a resistance estimation test. Indicates LV battery replacement is necessary.
<0.01% (Extremely rare)
None displayed
The LV battery may be unable to support precharge loads / precharge the high voltage (HV) bus, and requires replacement.
The low voltage (LV) battery internal resistance is too high, based on measured voltage being below the acceptable threshold during a resistance estimation test. Indicates LV battery replacement is necessary.
The LV battery voltage dropped below the lower limit during a resistance estimation test.
The vehicle controller loses all electrical power from the LV battery and power conversion system (PCS), as would happen during LV battery replacement.
