The vehicle controller detects the low voltage (LV) battery voltage is lower than expected during a precharge event. When this occurs too many times, separate alerts will also be present to indicate precharging the high voltage (HV) bus may not succeed and the LV battery may need replacement.

The LV battery may be unable to support vehicle electrical systems, including precharging the high voltage (HV) bus.

An instant resistance check of the LV battery connections to the vehicle controller does not succeed (does not return a healthy result). Alert log signal data should provide more information on specifics, including load current, LV battery temperature, and any detected voltage dip.
