Diagnostic Trouble Code
P0A80 — Replace Hybrid Battery Pack
Replace Hybrid Battery Pack
Definition
The hybrid battery management system has determined that the high-voltage battery pack has degraded beyond acceptable limits. Individual cell voltage imbalances or overall capacity loss has exceeded the manufacturer's threshold for safe and efficient operation.
Common Causes
- Normal age-related degradation of battery cells
- Individual cell failure causing voltage imbalance
- Excessive heat exposure degrading battery chemistry
- Cooling system failure for the battery pack
