"Idle Shutdown Time"
The "Idle Shutdown Time" 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. The idle shutdown timer will not begin counting if the engine is in cold mode. If this parameter is programmed to zero, this feature is disabled and the engine will idle until the key switch is in the OFF position.Note: This feature does not shut down the vehicle's power. The ECM and the vehicle remain powered.
Table 1
Minimum Maximum Default
3 minutes 1440 minutes 0 minutes "Idle Shutdown Timer Maximum RPM"
This parameter can be used to reset 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.

Minimum Maximum Default
600 rpm 2120 rpm 2120 rpm "Allow Idle Shutdown Override"
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, the parameter is turned off.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: When the timer is overridden, the engine will not shut down.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 sensor is not installed, 171-03 Ambient Air Temperature voltage high will be active for the sensor. If the "J1587 Outside Temperature Based" option is programmed and 171-11 Ambient Air Temperature Data Lost is active, the idle shutdown timer will be disabled.
