Judgment of Reuse of Filter Comp (DPF) Before Cleaning
(Service Dealer)
IMPORTANT
• Before ordering to a cleaning contractor, follow the
procedure below to make a judgment on whether the DPF
is reusable.
1. Check to see that the exhaust gas outlet side on the removed
DPF is not darkened.
2. Check whether there is no crack or failure of the sealing wall on
both ends of the cell (inlet side and outlet side) of DPF.
If the number of cells with failure sealing wall exceeds the
allowable limit, the DPF cannot be reused even after cleaning.
3. Check whether there is no crack and loss of the ceramic
element.
If there are any crack or losses of the ceramic element, the DPF
cannot be reused even if it is cleaned.
4. If it is judged that the DPF is not reusable, report the result of the
evaluation to the customer that requested the DPF cleaning,
and replace the DPF with a new one.
