VCFRONT_a407_dcrMilliOhmsAboveThreshold
Description
The low voltage (LV) battery internal resistance is too high, based on a direct current internal resistance (DCR) calculation. Indicates LV battery replacement is necessary.
Condition
Direct current internal resistance (DCR) calculation indicates the LV battery internal resistance exceeds expected threshold (normal operating range).
Clear Condition
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.
