Kia Optima: Oil Pump Uni t(OPU) Description and Operation

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.
