HINT:

When DTC P0524-77 is stored, it is determined that the engine oil pressure is low (severe) and the maximum engine speed is limited.
When DTC P15F0-09 is stored, it is determined that the engine oil pressure is low (moderate) and the maximum engine speed is limited.
When DTC P15F0-77 is stored, it is determined that the engine oil pressure is low (minor) and the maximum engine speed is limited.
If the engine oil level is sufficient but a low engine oil level DTC is output, confirm with the customer whether engine oil was added after the vehicle had been driven with a low engine oil level.
A DTC may be stored if the engine oil in the oil passages was contaminated with foreign matter, etc., in the past, as the ECM performs compulsory control of the oil pressure control valve assembly to remove foreign matter from the oil pressure control valve assembly.
If an incorrect engine oil viscosity is used, a DTC related to low oil pressure, etc., may be stored.
