What triggers it
Direct current internal resistance (DCR) calculation indicates the LV battery internal resistance exceeds expected threshold (normal operating range).
When it clears
The vehicle controller loses all electrical power from the LV battery and power conversion system (PCS), as would happen during LV battery replacement.
Potential impact
The LV battery may be unable to support precharge loads / precharge the high voltage (HV) bus, and requires replacement.
