P2CCCHybrid/EV Battery Pack G Deterioration

P2CCC indicates that the battery management system has detected abnormal deterioration in the high-voltage battery pack designated as 'G', typically by comparing its internal resistance, capacity, or cell balance against expected values. The computer sets this code when the pack's measured performance falls outside the manufacturer's acceptable degradation threshold, signaling that the pack is losing its ability to store and deliver energy efficiently.
