P2DA0: High Voltage System Voltage Performance
Standardized SAE J2012 code · P2Dxx codes
What does P2DA0 mean?
The high-voltage system voltage does not match plausibility checks under load. Voltage trace deviates from expected battery profile.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High HV battery cells aged
- Medium BMS regulation outside calibration
