Q: What does code P25ED mean?

Supercharger Disconnect Clutch Circuit High. P25ED means the engine control module (ECM) has detected an abnormally high voltage on the supercharger disconnect clutch control circuit, indicating an open circuit, a short to voltage, or a failed clutch coil. The ECM expects a specific voltage range when commanding the clutch on or off, and a reading above the calibrated threshold sets this code.
