UMMINS ® DIESEL
Your vehicle will require emissions
maintenance at a set interval. To help remind
you when this maintenance is due, the
instrument cluster will display “Perform
Service”. When the “Perform Service” message
is displayed on the instrument cluster 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.
