System Wiring Diagram
• Not applicable
Function Explanation (DTC Detection Outline)
• The PCM monitors the engine oil level while the preconditions are being met and if the monitoring time is 5 min or more or the traveled distance is 100 km {62.1 mile} or more, it calculates the average engine oil level.
• If the averaged engine oil level decreases below MIN mark two times in a row, the PCM stores a DTC and turns on the engine oil level warning light in the instrument cluster.
• If the averaged engine oil level decreases below MIN mark two times in a row, the PCM stores a DTC and displays the engine oil level warning indication on the multi-information display.
• If the ignition is switched off after the engine oil level warning light begins illumination, it stops the engine oil level warning light from illumination.
• If the ignition is switched OFF after the engine oil level warning indication is displayed, the engine oil level warning indication is not displayed.
• After verifying an engine oil level deficiency, the PCM re-implements the determination if the ignition is switched ON and if it determines that the engine oil level is insufficient, it turns on the engine oil level warning light in the instrument cluster.
• After verifying an engine oil level deficiency, the PCM re-implements the determination if the ignition is switched ON and if it determines that the engine oil level is insufficient, it displays the engine oil level warning indication in the multi-information display.
Repeatability Verification Procedure
1. Move the vehicle to a level area and switch the ignition ON (engine off).
2. Verify engine oil level using the dipstick (verify that it is near MIN mark)
