Kia Optima Hybrid: Hydraulic System / Oil Pump Uni t(OPU) Description and Operation

Description
The oil pump main relay is installed within the HEV fusible link box of the engine room. When the Oil Pump Unit (OPU) triggers the oil pump main relay, electric current needed to operate the Electric Oil Pump (EOP) passes through the Oil Pump Unit (OPU) and is supplied to the Electric Oil Pump (EOP).
In general, the Electric Oil Pump (EOP) operation is controlled by TCM via CAN communication, but in case of CAN communication failure, there is a back-up hard wiring between the TCM and Oil Pump Unit (OPU) as shown below.
