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 specification, determine the malfunctioning location referring to the following DTCs “Possible Cause” and repair or replace the applicable part.
― P0524:00 (Engine oil pressure too low)
― P055F:00 (Engine oil pressure control circuit low oil pressure)
― P06DD:00 (Engine oil pressure switch control circuit high input)
― P06DE:00 (Engine oil pressure switch control circuit low input)
Note
• The oil pressure can vary with oil viscosity, temperature, and engine speed.
Oil pressure (reference value) [oil temperature: 80—90 °C {176—194 °F}, coolant temperature: 80—90 °C {176—194 °F}]
