This message indicates the PCM has derated the engine
to limit the likelihood of permanent damage to the
after-treatment system. If this condition is not corrected
and a dealer service is not performed, extensive exhaust
after-treatment damage can occur. To correct this condi-
tion it will be necessary to have your vehicle serviced by
an authorized dealer.
NOTE: Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by 0 miles
remaining will prevent the diesel exhaust filter from per-
forming it's cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and reduced engine
power. Only an authorized dealer will be able to correct
this condition.
