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

id0140h0668700


Purpose

•  The engine oil level warning light/warning indication warns the driver that the engine oil level is at the MIN position on the oil level gauge, or the engine oil level sensor is malfunctioning.

Function

•  The PCM sends an engine oil level warning light illumination/warning indication request signal to the instrument cluster.
•  When the instrument cluster receives a engine oil level warning light illumination request signal/engine oil level warning indication request signal sent from the PCM via CAN communication, it turns the engine oil level warning light on or displays the engine oil level warning indication.

Construction

•  The engine oil level warning light is built into the instrument cluster.
•  The engine oil level warning indication is displayed in the multi-information display. (With multi-information display)

•  For vehicles equipped with the center display, a warning message is displayed in the center display as the same time the engine oil level warning light is turned on/engine oil level warning indication is displayed. For the message content and verification method, refer to [CENTER DISPLAY]. (See CENTER DISPLAY.)

Operation

•  The condition related to the engine oil level warning light is as follows.
―  PCM determines that engine oil level is in MIN position on oil level gauge
•  The condition related to the engine oil level warning indication is as follows.
―  PCM determines that engine oil level sensor is malfunctioning (With multi-information display)

Engine oil level warning light

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

2.  The instrument cluster turns the transistor on (2) based on the engine oil level warning light illumination request signal.

3.  When the transistor turns on, a ground circuit with the engine oil level warning light is established and the engine oil level warning light turns on (3).

Engine oil level warning indication

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

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