INITIALISATION PROCEDURE FOR LEARNING VALUE IN DIESEL PARTICULATE FILTER (DPF) SYSTEM <4N1-EURO5>

The engine-ECU stores the change of the DPF system caused by the various driving conditions as the learning value and uses it for assumption of the PM accumulated amount or for the acceptance/rejection criteria of the DPF system. For this reason, the learning value is necessary to be initialised when the parts related to the DPF system are replaced.
