ENGINE OIL DILUTION DETERMINATION (DTC P246C:00) [SKYACTIV-D 2.2]
id0180q1001200
Purpose of Adoption
• If the engine oil dilution amount (amount estimated by calculating the amount of fuel adhered to cylinder wall mixed into engine oil) exceeds the specified value, the engine oil warning light is illuminated and the user is notified that engine oil replacement is required.
Service Point
• Two methods are available for the engine oil dilution data reset. One is to use the MMDS, and the other is to short the test terminal as follows.
-
<Engine oil dilution data reset procedure>
1. Switch the ignition ON (engine off).
2. Ground the test terminal.
3. Perform engine racing 5 times within 5 seconds by fully closing/opening the accelerator pedal.
4. Verify that the glow indicator light flashes 5 times.
Common Inquiry
• If the oil dilution amount increases and the calculated estimation value exceeds the specified value, the oil replacement period is determined and the engine oil warning light is illuminated.
• After the engine oil is replaced, it is necessary to perform the dilution data reset regardless of whether or not the engine oil warning light was illuminated. If it is not reset, it could result in a mis-estimation of the oil dilution.
