DTC P2459:00

Diesel particulate filter regeneration frequency

DETECTION CONDITION

•  The PCM calculates mileage to the next oil replacement based on the vehicle driving conditions (engine load, frequency of the diesel particulate filter regeneration). If the calculated mileage reached necessary mileage of the oil replacement, the PCM stores DTC and turns the diesel particulate filter indicator light flash.

Diagnostic support note

•  FREEZE FRAME DATA (mode2) and snapshot data are not available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Vehicle is reached necessary mileage of engine oil replacement

•  Engine oil attenuation by frequently diesel particulate filter regeneration

•  Engine oil initialize procedure does not perform in each engine oil replacements
