12.4.2 Cold Weather Regeneration Aid Configuration
No configuration is required for this feature as all engine software contains the
ability to increase engine speed to aid regeneration when required.
12.4.3 Cold Weather Regeneration Aid Installation
For those applications wishing to activate the elevated engine idle strategy pin
46 of the engine ECM J1 connector must be connected to pin 18 the ground
switch return pin. Example wiring is shown below in figure 12.10.

This switch input can be enabled and disabled as required by the OEM. For
example the OEM could choose to only enable this strategy when the
operator is at the machine or the machine is in neutral etc.
12.5 Extreme Low Temperature Aftertreatment Ambient Air
Temperature Sensor
12.5.1 Aftertreatment Ambient Air Temperature Sensor Operation
An optional aftertreatment ambient air temperature sensor is available for all
Tier 4 Final/Stage IV engines, which can be installed to ensure adequate DEF
system thawing is performed. Fitment of this sensor will only be necessary
when ‘winterisation’ of the engine installation causes the Air Inlet Temperature
to deviate excessively from the prevailing ambient temperature. The
Aftertreatment Ambient Temperature sensor should be fitted as close as
possible to the DEF system (specifically the DEF lines), but away from any
heat source. Additionally, the sensor should be fitted in a location such as to
minimise risk of damage. Only the approved sensor should be installed.
12.5.2 Aftertreatment Ambient Air Temp Sensor Configuration
The aftertreatment ambient air temperature sensor requires EST configuration
to enable the feature when required. The factory default for this feature is Not
Installed. Configuration can be made via the main EST configuration screen
as shown below.
