5. Duster is still white.

Is the inspection result normal? YES >> INSPECTION END

NO >> GO TO 2.

2.CHECK DIESEL PARTICULATE FILTER-II

1. Put a new white duster.

2. With engine running in neutral position, make 10 accelerations.

3. Compare duster state with the first one (Step 1 - 5). If duster becames dark grey or black, diesel particulate filter is damaged.
