Components that are needed for Caterpillar Electronic Technician (Cat ET) | |
Caterpillar Electronic Technician (Cat ET) is a software program that is used to access, view, monitor and sometimes change the data that a particular ECM is using to control a machine system. The service technician can use Cat ET to perform maintenance on the machine. Some of the options that are available with Cat ET are listed below:
- View the active diagnostic codes and logged diagnostic codes. Refer to Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes".
- Viewing the active event codes and logged event codes
- View the status of parameters.
- Clear active diagnostic codes and clear logged diagnostic codes
- Perform calibrations of machine systems.
- Program the ECM (Flash) with the "WINflash" program. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".
- Print reports.
The following list contains some of the diagnostic functions and programming functions that are performed by Cat ET.
- The failures of the ECM system are displayed.
- The status of most of the inputs and the outputs are displayed.
- The settings for the ECM are displayed.
- Display the status of the input and output parameters in real time.
- Display the clock hour of the internal diagnostic clock.
- The number of occurrences and the clock hour of the first occurrence and the last occurrence is displayed for each logged diagnostic code.
- The definition for each logged diagnostic code and each event is displayed.
- Load new FLASH software.
- Active diagnostic codes
- Logged diagnostic codes
Refer to Troubleshooting, "Diagnostic Code List" for the list of diagnostic codes that can be activated by all of the Implement control modules.
