The Caterpillar Electronic Technician (ET)
The Caterpillar Electronic Technician (ET) is a software program that can be used on an IBM compatible personal computer. Cat ET is used to communicate to, and access data from the ECM over the data link by connecting to the service tool connector. Refer to the "Electrical System Schematic" section of this document in order to locate the service tool connector for a specific application.The service technician can use Cat ET in order to perform maintenance work on the engine. Some of the options that are available with Cat ET are listed below:
View the status of parameters
Perform calibration of engine systems
Program the ECM (Flash)
Print reportsNote: In order to "Flash" program the ECM, use the "WINflash" program. Refer to the "Electronic Control Module (ECM) - Flash Program" section of this document for information about the process to flash program the ECM.The following list contains some of the diagnostic functions and programming functions that are performed by the service tools.
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.
Load new FLASH software.Status Groups For The Electronic Technician
Cat ET is used as the primary reference in the discussion and Illustrations that follow. The reference to the Cat ET also implies a reference to the Caterpillar Communication Tool Kit when features are common between the two.Status Group 1 - Serial Port Statistics

Serial Port Statistics screens 1 and 2The PL1000E tracks the communications on its physical ports. The PL1000E displays the communications statistics on the Cat ET "Serial Port Statistics" screens. The first of the screens displays the communication statistics for serial ports 1, 2, and 3, that is, RS-232 Port 1, RS-232 Port 2, and RS-232 Port 3 respectively. The second of these screens displays the communication statistics for serial port 4 which is the RS-422 and 485 port. For each serial port, the physical layer bytes that are received, physical layer bytes that are transmitted, the physical layer receive errors, and the physical layer transmit errors are displayed. This information represents the communication statistics of the physical port and may include counts of bytes received or transmitted from various protocols on the same physical port. The physical communication statistics is a good tool to use to verify the ECM is successfully receiving data at the most basic level. The communication statistics on this page are automatically updated by the ECM every 1 second. These totals are the accumulated totals since the last "warm boot sequence" or "cold boot sequence" of the ECM (Keyswitch or power cycle). These totals are not "Lifetime" totals and will be reset with each "boot sequence" of the ECM. The "Clear Counters" button (password protected) simply forces these values to all zeros without the need for a "warm boot" or "cold boot".Physical Layer Bytes Received (Rx Bytes) -
