Q: What does code P2D9F mean?

High Voltage System Voltage High. P2D9F indicates that the high-voltage system voltage has exceeded the manufacturer's specified maximum, as detected by the battery energy control module or hybrid control module. The computer monitors the high-voltage bus and sets this code when the voltage rises above the safe threshold, often due to a charging system fault or a battery pack issue.
