Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not force-charge or service the high-voltage battery without manufacturer safety and balancing procedures.

Useful checks before replacing parts

Review battery state of charge, block voltages, pack voltage, temperature data, current flow, freeze-frame load, and related battery deterioration or charging codes.
Inspect 12-volt supply stability, service disconnect status, battery cooling operation, contactor status, and recent deep-discharge or storage history.
Confirm whether low state of charge is caused by pack imbalance, charging system limits, contactor trouble, or normal depletion.
