At 3000 hours a 5838-31 level 1 diagnostic code will
become active and the amber warning lamp will
become solid. This information is to inform the
operator that cleaning and reset are required. The
operator then has 100 hours to complete the cleaning
and reset.
If at 3100 hours the cleaning and reset has not been
performed, a 5838-14 level 2 diagnostic code will
become active. The amber warning lamp will start to
flash and the engine will be derated.
