The U019F code is a Controller Area Network (CAN) fault code. CAN is a vehicle bus standard designed to interconnect automotive devices without a host computer.

The code sets when a periodic message from the Engine Coolant Pump Control Module has not been received. The Diagnostic Trouble Code (DTC) indicates that there is a lost communication with the Engine Coolant Pump Control Module. The CAN bus uses two dedicated wires for communication, CAN high and CAN low.

The CAN bus is NOT sensitive to inductive spikes, electrical fields, or other noise.
