Idle Shutdown Timer
The idle shutdown timer can be programmed in order to shut down the engine after a specific time period of idling. The idle time can be programmed from three minutes to 1440 minutes (24 hours). If the idle shutdown timer is set to 0 minutes, the idle shutdown feature is disabled. If the setting of the timer is unknown, allow the engine to idle. Observe the time that elapses before the engine shuts down. The following conditions must be met in order to activate the idle shutdown timer:
The idle shutdown feature must be selected.
No vehicle speed is detected by the Electronic Control Module (ECM).
The engine is not under load.
The engine is at operating temperature. The engine is not in Cold Mode.After the vehicle is stationary, the idle shutdown timer begins. The engine can be operating at low idle or at an idle rpm that is selected by the idle governor. The "CHECK ENGINE/DIAGNOSTIC" lamp will flash rapidly for 90 seconds prior to shutdown. Movement of the vehicle automatically resets the idle shutdown timer to the programmed setting.The following conditions must be met in order to override the idle shutdown timer:
Program the "ALLOW IDLE SHUTDOWN OVERRIDE" to "YES".
The "CHECK ENGINE/DIAGNOSTIC" lamp will flash rapidly for 90 seconds prior to shutdown. Depress the service brake or the clutch pedal during the 90 seconds when the "CHECK ENGINE/DIAGNOSTIC" lamp flashes.After an idle shutdown, the engine can be restarted without turning the ignition switch to the OFF position.The override function is disabled if the "ALLOW IDLE SHUTDOWN OVERRIDE" is programmed to "NO".Cold Mode Operation
Cold mode is initiated if the coolant temperature is below 28° C (82° F). Engine power is decreased until the coolant temperature reaches the above value. In cold mode, the idle is 600 rpm for the C15. The strategy for cold mode provides reduced smoke emission and faster warm-up time.After the cold mode is completed, the engine should be operated at low rpm and low load until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low rpm and low power demand. This method is faster than trying to reach operating temperature by idling with no load.
It is not recommended that the vehicle be moved until the engine is out of cold mode. Power may be noticeably reduced if the vehicle is operated while the engine is in cold mode. At a speed above 8 km/h (5 mph), the low idle speed will be reduced to the customer programmed low idle speed. The power will still be reduced.
Cold mode is disabled if the throttle, the service brake, or the clutch (if equipped) is depressed. The rpm for cold mode operation drops to the programmed low idle speed in order to allow the transmission to be put into gear.Getting Started
Caterpillar electronic engines do not require long warm-up periods that needlessly waste fuel. Typically, the engine should be at normal operating temperature in a few minutes. Begin operating the
