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.
Table 2
Default Minimum Maximum
2120 rpm 600 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 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.

Default Alternative
Yes No
Outside Temperature Based
(J1587) Outside Temperature Based "Minimum Idle Shutdown Outside Temp"
This parameter determines the lower outside temperature limit when the "Allow Idle Shutdown Override" is programmed to one of the following options:
"Outside Temperature Based"
"J1587 Outside Temperature Based"
Table 4
Default Minimum Maximum
49 °C (120 °F) −40 °C (−40 °F) 49 °C (120 °F)
Illustration 1 g01261767
The "Allow Idle Shutdown Override" is programmed to the "Outside Temperature Based" option or to the "Outside Temperature Based (J1587)" option.
"Maximum Idle Shutdown Outside Temperature"
This parameter determines the upper outside temperature limit when the "Allow Idle Shutdown Override" is programmed to one option of the options that follow:
"Outside Temperature Based"
"J1587 Outside Temperature Based"Illustration 1 indicates that the "Allow Idle Shutdown Override" is allowed in the final 90 seconds of the timer's countdown. During the final 90 seconds, one of the following conditions must exist in order for the engine to be shut down:
The outside temperature is below the programmed "Minimum Idle Shutdown Outside Temperature".
The outside temperature is above the "Maximum Idle Shutdown Outside Temperature".

Default Minimum Maximum
49 °C (120 °F) −40 °C (−40 °F) 49 °C (120 °F) "A/C Switch Fan-On Time"
Note: Program this parameter only when a normally closed high pressure A/C switch is connected to P1-41.The timer prevents excessive cycling of the cooling fan clutch due to successive cycling of the A/C switch. Programming this parameter to "0" disables the function.The ECM has a built-in timer. This parameter programs the duration of the timer. Programming depends on the refrigerant, and the design of the air conditioning system as well as the use of the signal input. Program the timer to one second when another system also provides a time delay.This feature requires the "Fan Control Type" to be programmed to any value except "None".

Default Minimum Maximum
0 seconds 1 second 600 seconds "Engine Retarder Delay"
This parameter provides a programmable delay after provisions to turn on the engine retarder or the engine brake are met.
