Perform Service Indicator — Cummins® Diesel
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) or
Driver information Display (DID) will display "Perform Service". When the "Perform
Service" message is displayed on the EVIC/DID it is necessary to have the emissions
maintenance performed. Emissions maintenance may include replacing the Closed
Crankcase Ventilation (CCV) filter element. The procedure for clearing and resetting
the "Perform Service" indicator message is located in the appropriate Service
Information.
