| 1. HPCU (Hybrid Power Control Unit) (LDC+MCU+HCU+Reservoir) 2. Hybrid drive motor | 3. Hybrid starter generator (HSG) 4. Electrical radiator 5. Electric water pump (EWP) |
Description• 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.
Removal1.Remove the 12 V battery (-) cable.2.Remove the undercover.(Refer to Engine Mechanical System - "Engine Room Undercover".)3.Drain the coolant from the hybrid cooling system.
Self Diagnosis1.Self-diagnosis process. • When operating the self-diagnostics, the below fault (self-diagnostics code) will blink at 0.5 seconds interval on the temperature display settings (driver's side only) and the remaining symbols are OFF .
