WRENCH INDICATOR LIGHT/WRENCH INDICATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]

id0140g2266500


Purpose

•  The wrench indicator light/indication notifies the driver that the maintenance period previously set by the driver approaches, or that the PCM has determined engine oil deterioration.

Function

•  When a maintenance period previously set by the driver approaches, or if the PCM determines engine oil deterioration, the PCM sends a wrench indicator light illumination request signal/wrench indication request signal to the instrument cluster.
•  When the instrument cluster receives a wrench indicator light illumination request signal/wrench indication request signal sent from the connectivity master unit (CMU) or the PCM via CAN communication, it turns the wrench indicator light on or displays the wrench indication.

Construction

•  The wrench indication is displayed in the multi-information display. (With multi-information display)
•  The wrench indicator light is built into the instrument cluster. (Without multi-information display)

•  For vehicles equipped with the multi-information display, a warning message is displayed in the multi-information display as the same time the wrench indicator light is turned on/wrench indication is displayed. For the message content and verification method, refer to [MULTI-INFORMATION DISPLAY]. (See MULTI-INFORMATION DISPLAY.)
•  For vehicles equipped with the center display, a warning message is displayed in the center display as the same time the wrench indicator light is turned on/wrench indication is displayed. For the message content and verification method, refer to [CENTER DISPLAY]. (See CENTER DISPLAY [WITH CENTER DISPLAY].)

Operation

•  The wrench warning indicator light illumination conditions are as follows:
―  When the preset maintenance period approaches (See MAINTENANCE MONITOR [WITH CENTER DISPLAY].)
―  PCM determines engine oil replacement period reached. (See ENGINE OIL MAINTENANCE MONITOR [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (European specs.)

Wrench indicator light

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

2.  The instrument cluster turns the transistor on (2) based on the wrench indicator light illumination request signal.

3.  When the transistor turns on, a ground circuit with the wrench indicator light is established and the wrench indicator light turns on (3).

Wrench indication

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

2.  The instrument cluster displays (2) the wrench indication in the multi-information display.
