ENGINE OIL WARNING LIGHT [MZR 1.6]
id0140j7265700
Purpose/Function
• The engine oil warning light warns the driver that the engine oil level is insufficient.
• 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].)
• For instrument cluster type B, a warning message in the multi-information display is displayed simultaneously when the engine oil warning light is illuminated. For the message content, refer to the MULTI-INFORMATION DISPLAY. (See
MULTI-INFORMATION DISPLAY.)
Operation
• If the engine oil pressure is low, the PCM sends an engine oil pressure warning light on request to the instrument cluster.
Type A or type B instrument cluster
1. The instrument cluster receives (1) the engine oil warning light request signal from the PCM.
2. The instrument cluster microcomputer displays (2) the engine oil warning light in the LCD screen.
Type C or type D instrument cluster
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
• Function not equipped.
