WRENCH INDICATOR LIGHT [SKYACTIV-D 1.5]
id0140z5265500
Purpose/Function
• The wrench warning indicator light turns on to alert the driver of engine oil deterioration or that the preset maintenance period is approaching.
• The wrench warning indicator light flashes to alert the driver that draining of the sedimentor is required.
Construction
• The wrench indicator light is built into the instrument cluster.
Operation
• The conditions related to the wrench indicator light illumination/flashing are as follows.
Wrench indicator light illumination conditions
-
― PCM determines that engine oil has deteriorated
― Preset maintenance period approaches
-
Wrench indicator light flashing conditions
-
― Vehicle was driven 20,000 km {12,427 mile} (distance specified for sedimentor draining during periodic inspection servicing) since sedimentor data reset was performed
― During fuel injector carbon deposit burn-off
1. If the PCM detects engine oil deterioration or an excess engine oil level, it sends (1) the wrench indicator light request signal to the instrument cluster.
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
