1.  Connect the M-MDS to the DLC-2.
2.  Start the engine and warm it up.
3.  Select the engine hydraulic pressure (PID: OIL_PRES) and the engine speed (PID: ENG_RPM) using the M-MDS data monitor function.
4.  Verify the engine hydraulic pressure (PID: OIL_PRES) value while the engine maintains a constant speed.
– If not within the standard, determine the malfunctioning location referring to the following DTCs [Possible Cause] and repair or replace the applicable part.
P0524:00
P055F:00
Note:
– The oil pressure can vary with oil viscosity, oil temperature, and engine speed.
– Oil pressure (reference) [oil temperature 80 – 90 °C {176 – 194 °F}, water temperature 80 – 90 °C {176 – 194 °F}]
Low hydraulic pressure: 92 – 114 kPa [1,500 rpm]
High hydraulic pressure: 176 – 204 kPa [4,500 rpm]
