Extended Idling and Aftertreatment System
Conditioning

Extended idling performed on this vehicle equipped with an exhaust
aftertreatment system should be carried out at a low engine idle speed. There
is no benefit to using a raised engine idle speed for extended idling. The only
exception is for active PTO . Utilizing an engine speed above 1300 rpm is
recommended for vehicles which perform extended idling with an active PTO.

During periods of extended idling, normally greater than 8 hrs, the conventional
DPF system needs to perform a routine conditioning cycle. The conditioning
cycle is controlled by the Engine ECU and will start and stop automatically
as needed. The ATS conditioning is required to maintain normal exhaust
aftertreatment system function and should not be stopped. ATS conditioning
will not occur on TRU DPF systems.

During these events the engine speed will increase to approximately
1050–1400 rpm, for non-PTO , in order to complete the exhaust aftertreatment
conditioning cycle. Exhaust temperatures will also elevate slightly but remain
much lower than those reached during regeneration and present no danger.

If a compatible driver display is available a message will be displayed when
the conditioning cycle is in progress. The message indicated in the driver’s
display will be "ATS Conditioning in Progress, No Action Required." If no driver
