Caterpillar Electronic Technician (Cat ET) is diagnostic software required to communicate, diagnose and service electronically controlled Caterpillar engines and machines. When connected to an Electronic Control Module (ECM), a technician has the ability to diagnose existing and potential problems, configure the product and obtain data for analysis.
Cat ET features:
- View active and registered diagnostics.
- View events where irregularities occurred and were recorded by the ECM.
- View the status of a group of parameters (temperatures, pressures, etc.) simultaneously.
- Register and record performance data.
- Graph a group of state parameters.
- View the current configuration of an ECM.
- Change ECM configurations.
- Diagnostic tests.
- Calibrations.
- Print reports and diagnostic results.

Flash files: ECM (Electronic Control Module) flash files for various U.S. Military models are included in the download package. Use the cross-reference table below to identify the correct flash file for your application. The flash files are cross-referenced by Caterpillar Serial Number Prefix, Caterpillar Model, Name/Military Model, and ECM Description. Note the appropriate flash file folder to locate the file. The Caterpillar serial number prefix is the first three (3) characters of the eight (8) character serial number. For Caterpillar Machines the serial number is the last eight (8) characters of the Caterpillar product Identification Number (PIN).
