What does code P2D00 mean?

Q: What does code P2D00 mean?

Motor Electronics Coolant Pump A Stuck/Stalled. This code means the engine control module has detected that the electric coolant pump responsible for circulating liquid through the motor electronics cooling circuit is not turning as commanded, either stuck stationary or stalled under load. The module monitors the pump's electrical current and feedback signal, and when the expected motion or current draw does not match the command, it stores this fault and typically illuminates the warning light.
