Q: What does code P2514 mean?

Event Data Recorder Request Circuit High. P2514 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the event data recorder (EDR) request circuit, which is the communication line used to trigger the EDR to capture and store vehicle data during a crash event. The PCM expects a specific voltage range on this circuit and sets the code when the signal exceeds the upper threshold, indicating a short to voltage or an open circuit.
