ENGINE OIL WARNING LIGHT [SKYACTIV-G 2.0, SKYACTIV-G 2.5]
id0140g2265700
Purpose
• The engine oil warning light warns the driver that the engine oil level is insufficient.
Function
• If the engine oil pressure is low, the PCM sends an oil warning light illumination request signal to the instrument cluster.
• When the instrument cluster receives the oil warning light illumination request signal sent from the PCM as a CAN signal, it turns the oil warning light on.
Construction
• 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).
