What does code P2DB6 mean?

Q: What does code P2DB6 mean?

Battery Charger B Cooling System Performance. P2DB6 indicates that the powertrain control module has detected a performance fault in the cooling system for the high-voltage battery charger, meaning the charger is not staying within its expected temperature range during operation. The computer typically sets this code when the charger coolant temperature rises too high or fails to reach the expected value within a calibrated time, based on signals from the charger coolant temperature sensor.
