Q: What does code P2CCE mean?

Hybrid/EV Battery Pack I Deterioration. P2CCE indicates that the hybrid or electric vehicle's battery management system has detected deterioration in battery pack 'I', meaning one or more modules or cells within that pack are losing capacity or increasing internal resistance beyond expected limits. The computer compares measured voltage, current, and temperature behavior against stored models to flag the pack as degraded rather than simply out of balance.
