| • | Function : It circulates the coolant for the hybrid system (HPCU, drive motor, and HSG). |
| • | Operating Principles: When the coolant temperature exceeds the limit set in the MCU in the hybrid system, the motor control unit (MCU) sends a command to the electric water pump (EWP) through the CAN communication to operate the EWP. EWP then sends its operation status to MCU through the CAN communication.
