What does code P0CC4 mean?

Q: What does code P0CC4 mean?

Drive Motor A Coolant Pump Control Circuit High. P0CC4 indicates that the powertrain control module has detected an abnormally high voltage on the control circuit for the coolant pump that serves drive motor A, which is the main traction motor in a hybrid or electric vehicle. The circuit is expected to operate within a specific voltage range, and a high reading typically points to an open circuit, a short to voltage, or a faulty pump module.
