ted service menu items will also be listed and available
in the service screen.
NOTE: If the protected menu items are available, PIN

Key On identifies the number of hours that the igni-
tion switch has been in the ON position.

DPF Regeneration provides the necessary proced-
ure for stationary regeneration for the exhaust system
DPF (diesel particulate filter) on machines with a Tier 4
engine (models 30881 and 30882). If the engine ECU
identifies that a stationary DPF regeneration is neces-
sary, an advisory will occur on the InfoCenter and the ne-
cessary steps will be listed in the service screen menu.
Traction Pedal allows the traction pedal sensor to
be calibrated (see Traction Pedal Position Sensor Calib-
ration in the Adjustments section of this chapter for calib-
ration procedure).
Fan Reverse provides the necessary inputs to
cause the cooling fan to reverse direction. This protec-
ted menu item allows the demonstration of the fan re-
versal and would never be necessary to use on a
normally functioning machine.
