OIL MAINTENANCE MONITOR

id099000002300


Purpose of Adoption

•  Estimates the level of oil deterioration based on the driving conditions and environment in which the vehicle is driven and informs the driver of the appropriate oil replacement period.

Service Point

•  The initial setting of the oil maintenance monitor is OFF at the time of shipment. Turn the system on using the diagnostic tester. After oil replacement, a system reset procedure needs to be performed.
•  For diesel engine vehicles, if the Flexible function of the oil maintenance monitor is off, the oil dilution determination system data needs to be reset.
•  If the PCM determines that the oil has deteriorated, or it has reached the set maximum distance traveled, it illuminates the oil replacement lamp. The maximum period which can be set is 12 months, and the distance is 20,000 km. The lamp does not illuminate at 10,000 km or less from the previous reset.
•  For vehicles with the center display, the oil life is indicated as a percentage in the center display. The condition of newly replaced oil (at reset) is defined as 100%, and the value decreases according to the driving conditions and environment in which the vehicle is driven. The display indicates increments of 10%. Oil Change Due is displayed when the remaining travel distance to the oil replacement period is 500 miles or 15 days prior to it.

Common Inquiry

•  Depending on the driving conditions and environment in which the vehicle is driven, the lamp may illuminate at a shorter distance than the fixed maintenance interval under normal conditions.
•  Example:
―  Gasoline engine: Frequent amount of short-distance travel
―  Diesel engines: High frequency driving under conditions of high soot occurrence (frequent accelerator on/off), and high frequency of driving under highly diluted fuel conditions (high frequency of short-distance driving)
―  No reset after previous oil replacement (Oil is replaced when oil replacement lamp was not illuminated, and the possibility that reset was not performed)
