ET4 Diagnostic Tool from Caterpillar provide the capability to access Electronic Control Modules (ECMs) from a personal computer. Many job-critical tasks can be performed with an electronic service tool. The user can display the status of a group of parameters (temperatures, pressures, etc.) simultaneously, view active and clear logged diagnostics, display the current configuration of an ECM and much more. The service tool works with a communication adapter to allow connection to an ECM. A graphical interface makes this software quick to learn and easy to use. A separate pull-down menu for each function enhances the "ease of use." The version and identification of the ECM is automatically retrieved and is displayed on a summary screen when the program is started. Diagnostic tests and calibrations can also be performed.

ET4 Diagnostic Tool enable service technicians to reprogram ECMs, reconfigure control system parameters, fine tune performance or diagnose the root cause of a failure the first time. These powerful tools allow service personnel to display and analyze vital performance and health information from any system quickly and accurately. The service tool communicates with any system using ATA (J1708), J1939 or the Caterpillar proprietary data link networks. The service tools provide information and features needed to help a technician diagnose problems and perform repairs and to customize and personalize the operation of a product. By allowing customers to design flexibility and configurability into a product, Caterpillar service tools stretch beyond the capabilities of preprogrammed ECMs or onboard display systems.
