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 ignore an overcharged high-voltage battery condition because thermal and contactor protection may be affected.

Useful checks before replacing parts

Review battery state of charge, regenerative braking data, block voltages, pack current, temperature data, freeze-frame conditions, and related charging codes.
Inspect battery control module data, current sensor plausibility, converter or inverter command, contactor status, and battery cooling operation.
Determine whether high state of charge is real, sensor-related, or caused by charging control that is not limiting current correctly.
