(1) Jacket water aftercooling or separate circuit aftercoolingThe following parameters are programmed at the factory to “0”:
"Crank Duration"
"Maximum Number Of Crank Cycles"The “0” settings prevent the Electronic Control Module (ECM) from engaging the starting motors. The settings must be reprogrammed before the engine will crank.Ensure that the "Air Shutoff" and the "Ether Control" parameters are "Enabled/ON" (if equipped) . If the engine does not have these options, ensure that these two parameters are "DISABLED/OFF".If the engine is equipped with Prelube, the "Engine Prelube Duration" must be programmed to a value that is greater than “0” seconds. Otherwise, the prelube pump will not cycle. If the engine is not equipped with Prelube, the parameter must be programmed to “0”.The engine will have either jacket water aftercooling or separate circuit aftercooling. The correct configuration of the aftercooling system must be programmed.No password is required for programming a new ECM during the first 100 hours of service life. This 100 hour “free configuration” feature enables the customer to tailor the programmable setpoints to the requirements of the installation. Exceptions are "Fuel Limit" and "Personality Module Mismatch".Air Shutoff
Note: This is an optional feature.The air shutoff uses a plate that rotates on a shaft in order to shut off inlet air to the aftercooler. The engine stops because of the restricted air supply to the combustion chamber. The air shutoff only actuates for the following conditions:
The Emergency Stop button is pressed.
An overspeed shutdown occurs.
The operator manually activates the air shutoff with the emergency air shutoffs on the engine. It is necessary to activate both of the air shutoffs in order to shut down the engine.Both of the air shutoffs must be reset before the engine can be restarted.

Reset knob for the air shutoff
To reset the air shutoff, turn the reset knob to the "OPEN" position.Ensure that both of the air shutoffs are reset.Cold Cylinder Cutout
Note: This feature can be enabled or disabled with an electronic service tool.The Cold Cylinder Cutout feature provides the following benefits:
Reduction of white smoke during cold starting
Reduction of the duration of advanced timing (cold mode)
Reduction of ether injectionThe ECM automatically turns off one electronic unit injector at a time during the following occurrences:
Cold start-up
Extended time at low idleThe ECM monitors the change of the fuel rack in order to determine if a cylinder is firing. If the cylinder is firing the ECM activates the electronic unit injector. If the cylinder is not firing the electronic unit injector remains deactivated. This reduces white smoke.The following conditions must be met in order to activate the Cold Cylinder Cutout:
The Cold Cylinder Cutout parameter is programmed to "ENABLE".
The fuel rack is less than 13 mm (0.5 inch).
The temperature of the jacket water is less than 63 °C (145 °F).The Cold Cylinder Cutout strategy is activated under either of the following conditions:
Ten seconds after the engine reaches the low idle rpm
Three seconds after ether injection is completedThe following conditions will deactivate the Cold Cylinder Cutout:
The Cold Cylinder Cutout parameter is programmed to "DISABLED".
The temperature of the jacket water is more than 70 °C (158 °F).
An ET service tool is used for the cold cylinder cut-out test.
The ether injection system is used.
The coolant temperature sensor has failed.
The engine is operating at a certain rpm when the Cold Cylinder Cutout is activated. If the engine rpm then varies by more than 50 rpm, the feature is deactivated for three seconds. A new engine speed is established when the feature is reactivated.
The engine is at low idle rpm for ten seconds. If the engine speed is then reduced by more than 50 rpm, the Cold Cylinder Cutout is deactivated for 30 seconds.
If the fuel rack is greater than 13 mm (0.5 inch), the Cold Cylinder Cutout is deactivated for one second.Droop
This feature enables an engine to share a load with other engines. If an engine is operating at high idle rpm and a load is applied, the engine rpm is reduced. The engine rpm is reduced as the load increases. This reduction in rpm is the droop. The droop can be programmed from zero to ten percent. If the percent of droop is equal for two identical engines in parallel operation, the engines share the load equally.Ether Control
Note: This is an optional feature.The ECM automatically injects ether into the air inlet manifold when the following conditions are met:
The engine rpm is greater than 75 rpm.
The temperature of the jacket water is below 31 °C
