What does code P2DA0 mean?

Q: What does code P2DA0 mean?

High Voltage System Voltage Performance. P2DA0 indicates that the high-voltage system voltage is outside the expected operating range, typically too low or too high for the current conditions. The hybrid or electric vehicle control module monitors the high-voltage bus and sets this code when the measured voltage deviates from the commanded or expected value beyond a calibrated threshold.
