"Idle Shutdown Time"
This parameter is the time (minutes) of engine idle before shutting down. The engine will only shut down if the Engine Control Module (ECM) senses low engine load and no vehicle speed.This feature is disabled and the engine will idle until the key switch is in the OFF position if this parameter is programmed to zero minutes.Note: This feature does not shut down the vehicle's power. The ECM and the vehicle remain powered.
Table 1
Default     Minimum     Maximum    
0 minutes     1 minute     1440 minutes    "Idle Shutdown Timer Maximum RPM"
This parameter resets the "Idle Shutdown Timer" if engine speed goes above the programmed "Idle Shutdown Timer Maximum RPM". Programming this parameter to 2120 rpm disables this feature. By disabling this feature, the "Idle Shutdown Timer" cannot be overridden by increasing the engine rpm. If this parameter is programmed to a value below 2120 rpm and the "PTO Shutdown Timer" is used, the timer will be reset when the engine rpm exceeds the programmed value.

This parameter determines if the clutch or the service brake can be used to override the idle shutdown timer during the driver alert. The driver alert is the last 90 seconds when the check engine lamp begins flashing. This parameter requires the "Idle Shutdown Time" to be programmed to three or more minutes for the parameter to be enabled. When the "Idle Shutdown Time" is programmed to zero minutes, this feature is disabled.In order to override the timer under the following conditions, depress the clutch or the service brake if the parameter is programmed to "Outside Temperature Based" or "J1587 Outside Temperature Based" and the driver alert is activated. Depression of the clutch or the service brake will override the timer:
The outside temperature is below the programmed "Minimum Idle Shutdown Outside Temperature".
The outside temperature is above the" Maximum Idle Shutdown Outside Temperature".Note: The engine will not shut down when the timer is overridden.If the outside temperature is between the "Minimum Idle Shutdown Outside Temperature" and the "Maximum Idle Shutdown Outside Temperature", the timer is not overridden and the engine will shut down. If the "Outside Temperature Based" option is programmed, an air temperature sensor must be installed in order to measure the outside temperature. If the "J1587 Outside Temperature Based" option is programmed and a 171-11 diagnostic code is active, the idle shutdown timer will be disabled.
