Idle Shutdown Time
Time (in minutes) that engine will idle before shutting down. Engine will only shut down if 3100 HEUI 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 ignition key switch is in the OFF position.
NOTE: This feature does not shut down vehicle power. The ECM and vehicle remain powered.
Allow Idle Shutdown Override
Determines if the clutch or service brake can be used to override the idle shutdown timer during the driver alert (in the last 90 seconds when the Check Engine Lamp begins flashing). Requires Idle Shutdown Time to be programmed in the 3 to 60 minute range to function (0=OFF).
