ENGINE OIL WARNING LIGHT [SKYACTIV-D 2.2]
id0140z7265700
Purpose/Function
• The oil warning light alerts the driver that the engine oil pressure has decreased while the engine is running or that the engine oil is diluted.
• If the PCM determines that the engine oil pressure has decreased while the engine is running or that the engine oil is diluted, it sends an oil warning light on request signal to the instrument cluster.
• When the instrument cluster receives the engine oil warning light request signal sent from the PCM via the CAN signal, it illuminates the engine oil warning light.
Construction
• The instrument cluster controls illumination on/off of the engine oil warning light using the instrument cluster microcomputer based on the engine oil warning light request signal from the PCM.
• The engine oil warning light is equipped in the instrument cluster.
• For vehicles with center display, a warning message in the center display is displayed when the engine oil warning light is illuminated. For the message content and verification method, refer to the CENTER DISPLAY. (See
CENTER DISPLAY [WITH CENTER DISPLAY].)
Operation
1. The instrument cluster receives (1) the engine oil warning light request signal from the PCM.
2. The instrument cluster microcomputer turns the transistor on (2) based on the engine oil warning light request signal.
3. When the transistor turns on, a ground circuit with the engine oil warning light is established and the engine oil warning light illuminates (3).
Fail-safe
