Cummins Diesel
Your vehicle will require emissions mainte-
nance at a set interval. To help remind you
when this maintenance is due, the instru-
ment cluster will display “Perform Service”.
When the “Perform Service” message is dis-
played on the instrument cluster it is neces-
sary to have the emissions maintenance per-
formed. Emissions maintenance may include
replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clear-
ing and resetting the “Perform Service” indi-
cator message is located in the appropriate
Service Information.
