Application Overview About Caterpillar Electronic Technician Caterpillar Electronic Technician (Cat ET) is a service tool designed to run on a personal computer (PC) under Microsoft Windows . With Cat ET you can display the status of a group of parameters (temperatures, pressures, etc.) simultaneously, view and clear active and logged diagnostics, or display the current configuration of an Electronic Control Module (ECM). Cat ET can perform these as well as many other tasks, such as: • • • • • • • •

Display parameter status View and clear diagnostics View events where irregularities occurred and were logged by the ECM View and change configuration of the ECM Perform diagnostic tests Perform calibrations View Trip information through Trip Summary, Histograms and Custom reports Print reports and diagnostic results

For some subscriptions of Caterpillar Electronic Technician, additional programs have been included with the Cat ET program. Caterpillar Electronic Technician is designed to communicate with the ECMs through a communication data link. Caterpillar Electronic Technician allows you to obtain data, analyze it, and then diagnose existing and potential problems.

About Caterpillar Electronic Technician Documentation All Caterpillar Electronic Technician documentation assumes the user has some Microsoftâ Windows experience. If this does not describe you, please take some time to acquaint yourself with Windows 95, 98, or NT before installing Caterpillar Electronic Technician. The data and menus that are displayed in the illustrations of this manual may be different from the data and menus that you have displayed in Caterpillar Electronic Technician. The reason for this is that the data depends on the Electronic Control Module (ECM) that Caterpillar Electronic Technician has targeted as the current ECM.
