Electronic Control System
Various sensors feed engine data to the electronic control module (ECM). The ECM processes this data. The ECM sends electronic signals to the unit injector solenoids. The solenoids are energized in order to start the fuel discharge from the unit injectors. The solenoids are de-energized in order to stop the fuel discharge from the unit injectors. Refer to Systems Operation, "Electronic Unit Injector" for a complete explanation of the fuel injection process.CAT Data Link
The engine incorporates a CAT data link. The data link is used to communicate with other devices that are based on a microprocessor.The CAT data link can reduce the duplication of sensors within the system by allowing controls to share information. The CAT data link is used to communicate information about the engine to other electronic control systems. The CAT data link is also used to interface with the electronic service tool.The information about the engine or the machine that is monitored and available on the CAT data link includes the following items.

These parameters include the following information: the engine serial number, the machine identification, the Full Load Setting (FLS) and the Fuel Ratio Control (FRC) Offset.When you are trying to set a parameter that requires a factory level security password, the electronic service tool will display a "Factory Password" screen. The password entry screen will display the ECM Serial Number, the Engine Serial Number, the electronic service tool Serial Number, and the total tattletales. In order to acquire these passwords, this information must be shown to an authorized Caterpillar dealer. Factory passwords are controlled by Caterpillar, Inc. The factory passwords may be obtained by authorized Caterpillar dealers.Note: The passwords are only good for one clearing session. A different set of passwords will be needed after exiting the Display/Change Parameters screen of the electronic service tool.The tool plugs into the connector for
