CAT Caterpillar ET 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.
COURSE PURPOSE:
This course has been designed to provide participants with the knowledge and skills necessary to use Caterpillar Electronic Technician to monitor, test, adjust, calibrate and troubleshoot Diagnostic Scan Tool Caterpillar Electronic Control Systems.
The course starts with Sensor interpretation and diagnosis, then Data Links, diagnosing and testing, ECMs and their inputs and outputs with relation to the 8 Steps of Troubleshooting. Then CAT ET program navigation and use with a practical component.For more information about the electronic service tool on www.cnautotool.com
