ENGINE OIL WARNING INDICATION/ENGINE OIL WARNING LIGHT [SKYACTIV-G 2.5T]

id0140h0320000

Purpose

• The engine oil warning indication/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 indication/engine oil warning light illumination request signal to the instrument cluster.

• When the instrument cluster receives the oil warning indication/engine oil warning light illumination request signal sent from the PCM as a CAN signal, it turns the oil warning indication/engine oil warning light on.

Construction

• The engine oil warning indication/engine oil warning light is equipped in the instrument cluster.

• For vehicles equipped with the multi-information display, a warning message is displayed in the multi-information display as the same time the engine oil warning indication is displayed. For the message content and verification method, refer to [MULTI-INFORMATION DISPLAY]. (See MULTI-INFORMATION DISPLAY.)

• For vehicles with center display, a warning message in the center display is displayed when the engine oil warning indication/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

Engine oil warning indication

1. When the ignition is switched ON (engine off or on), the instrument cluster receives (1) a engine oil warning indication request signal from the PCM or the CMU via CAN communication.

2. The instrument cluster displays (2) the engine oil warning indication in the multi-information display.

Engine oil warning light

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).
