(2) When the "Regeneration switch ON identification" value is ON,
wash or replace the filter.
When the value is OFF, DPR functions normally.
3. DPR DIFFERENTIAL PRESSURE CHECK
(1) Check the DPR differential pressure through the "DPR Status"
display.
(2) Check and confirm the exhaust gas temperature (in and out) is
less than 200C {392F}.
(3) Engine speed will rise automatically, then record the indicated
maximum DPR differential pressure.
(4) In case the central value of the recorded DPR differential pressure
value exceeds the specific value, clean or replace the filter.
Then "Stop" the DPR differential pressure check.
