Water Pump: Description and Operation

Description

The Electric Water Pump (EWP) circulates coolant of the cooling circuit for the Hybrid system (HPCU, HSG).
When the hybrid system coolants temperature rise over the threshold (set in the MCU), MCU sends the command signal to EWP by CAN communication to operate EWP, and the temperature below the set value then sends stop signal.
EWP sends the status information of itself to MCU whether EWP is in fail or not by CAN communication
