Description And Operation: Description

WARNING: This page is about a different variant/trim than selected.

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