LOCK 2A4465 - Caterpillar

Proper operation, driving techniques and maintenance are key factors in obtaining the maximum service life and economy of Caterpillar engines. The recommendations in this Operation and Maintenance Manual will help to lower operating costs. For more information, refer to Special Publication, LEDT2254, "CAT Answers Your Questions About Truck Performance" or consult your Caterpillar dealer.Idling
Idle speed is adjustable on Caterpillar electronic engines. Consult your Caterpillar dealer for information. The idle rpm is preset at 600 rpm.Avoid excess idling. If the vehicle is parked for more than five minutes, stop the engine. An engine can burn from 2.8 L (.7 US gal) to 5.7 L (1.5 US gal) of fuel per hour while the engine is idling. Excessive idling can cause carbon buildup and/or excessive idling can cause the engine to slobber. Excessive idling, carbon buildup, and engine slobber is harmful to the engine.If extended idle time is required, control the engine rpm to 1000 rpm or above 1000 rpm. Ensure that the coolant temperature exceeds 82° C (180° F), Consult your Caterpillar dealer for assistance.Fast idle can be programmed within the range of 700 rpm to the Top Engine Limit (TEL). Fast idle requires an "ON/OFF" switch on the dashboard. Consult your Caterpillar dealer for assistance.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 one minute 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 start to flash at a rapid rate (Driver alert) 30 seconds before the programmed idle time expires when the idle shutdown timer is programmed to one minute. The lamp will start to flash 90 seconds before the programmed idle time expires when the programmed idle time is 2 minutes or more. The flashing lamp alerts the driver the engine is about to shut down.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 30 to 90 seconds prior to shutdown. The service brake or the clutch pedal must be depressed during the 30 to 90 seconds when the lamp is flashing. A diagnostic EVENT code for Override of the Idle Shutdown Timer will be logged in the ECM. Movement
