Purpose
The engine oil pressure warning light warns the driver that the engine oil level is insufficient.
Function
When the instrument cluster receives the engine oil pressure warning light request signal sent from the PCM via the CAN signal, it illuminates the engine oil pressure warning light.
Construction
The instrument cluster controls illumination on/off of the engine oil pressure warning light using the instrument cluster microcomputer based on the engine oil pressure warning light request signal from the PCM.
The engine oil pressure warning light is set in the instrument cluster.

Operation
1. The instrument cluster receives (1) the engine oil pressure warning light request signal from the PCM.
2. The instrument cluster microcomputer turns the transistor on (2) based on the engine oil pressure warning light request signal.
3. When the transistor turns on, a ground circuit with the engine oil pressure warning light is established and the engine oil pressure warning light illuminates (3).
