Cold Mode Operation
A truck equipped with a 3176 Engine, which after it has completed the cold mode and the cold mode is disabled, cannot be enabled again until the ECM is powered OFF.
The cold start strategy will be activated when the coolant temperature is below 63°F (17°C). Once activated, it will continue until the coolant temperature reaches 82°F (27°C), or until the engine has been running for 12 minutes. This strategy involves the following steps.The 3176 system automatically idles the engine at 1000 rpm for the correct warm up time after a cold engine start. The 3176 system checks the engine coolant temperature sensor and will reduce the idle speed to programmed low idle speed when the engine is warm enough to drive the truck.1. The engine power available is reduced when the engine is in Cold Mode.2. If the cold start strategy is active and the ECM measures a vehicle speed, cold mode rpm will be de-activated.3. A timer will disable the cold mode strategy after 12 minutes. The time needed for the engine to reach the normal mode of operation is usually less than the time taken for a walk-around-inspection of the vehicle.After Cold Mode strategy is completed, the truck should be operated at low rpm and low power until normal operating coolant temperature 175° to 205°F (79° to 98°C) is reached.The engine will reach operating temperature faster when driven at low rpm and low power demand than when idled at no load. Typically the engine should reach operating temperature when driving through the yard toward the open road.If the engine speed is not controlled by the PTO governor function while in the cold mode, the engine idle will be reduced to programmed low idle automatically when the cold mode is completed.Engine Operation
* Begin operating the engine at low load. After normal oil pressure is reached and the temperature gauge begins to move, the engine may be operated at full load.* To get the vehicle in motion, use a gear that will result in a smooth, easy start to move the load without increasing engine speed above low idle or slipping the clutch. Engage the clutch smoothly. Interrupted slipping and abrupt clutch engagement put stress on the drive train and waste fuel. It is not necessary to advance the throttle to get the 3176 equipped truck moving from a stop in most instances.* Use progressive shifting to reduce fuel consumption. Progressive shifting is using only the rpm required to make an upshift into the next gear. The amount of rpm required to make an upshift increases as the truck speed increases unless upshifts are made on upgrades. Experience with your truck will show you how much rpm is required to make upshifts under various conditions. Your 3176 engine may be programmed for Low and High Gears RPM Limiting (progressive shift control).* If the truck can be operated in a higher gear after the desired speed is reached, select the highest gear available that will pull the
