WRENCH INDICATOR LIGHT [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5]
id0140g5265500
Purpose
• The wrench indicator light notifies the driver that the maintenance period previously set by the driver approaches.
• The wrench indicator light notifies the driver that the PCM has determined engine oil deterioration. (European specs.)
Function
• When a maintenance period previously set by the driver approaches, or if the PCM determines engine oil deterioration (European specs.), the PCM sends a wrench indicator light illumination request signal to the instrument cluster.
• When the instrument cluster receives a wrench indicator light illumination request signal sent from the connectivity master unit (CMU) or the PCM via CAN communication, it turns the wrench indicator light on.
Construction
• The wrench indicator light is built into 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
1. When the ignition is switched ON (engine off or on), the instrument cluster receives (1) an 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).
Fail-safe
