Use CAT Electronic Technician WinFlash Function

CAT ET diagnostic software’s WinFlash function is a useful tool for setting up and programming the Flash memory of onboard ECMs. This guide will show you how to use Caterpillar Electronic Technician service tool’s WinFlash function effectively.

To access the WinFlash tool, you can either select “WinFlash” from the Utilities menu or click on the WinFlash icon on the toolbar.

Once you open the tool, the Connection message box will appear, indicating that WinFlash is establishing communication with the ECM(s). You can stop the connection process by clicking the Stop Connect button if needed. Please note that this connection process will be displayed regardless of the connection status.

If you want to utilize the flash function via Ethernet, you can refer to the IP Flash over Ethernet option. However, please keep in mind that IP Flash over Ethernet is only supported for flashing and is not available for general servicing.

The WinFlash screen has several areas:

1. Menu Items: These menus offer various functions, similar to the service tool main screen. However, two exceptions are worth noting:
– File…Update ECM List: Select this option to update the ECM list once you establish a connection with WinFlash. This will reestablish communication between any ECM(s) and WinFlash.
– File…Return to [service tool]: This option allows you to exit the WinFlash screen and return to the service tool main screen.

2. ECM Information area: This area lists all the ECMs on the data link and provides details such as the ECM type, data link type, ECM serial number, and Current Software part number. If an ECM is programmable and the connection has been established, an icon will indicate it. If the connection has not been established, the ECM will be marked as not programmable.

3. Flash File Information area: When you select a file from the File Selection dialog box, the file name, location, and a brief description (if available) will be displayed. In this area, you’ll find buttons like Browse (to search for files on your computer or network location) and Search (to search for files based on preferences set in the CBT tab of the Preferences dialog box). You can also remove selected files from this area.

4. ECM/File Information area: This area is visible when a flash file is selected. It consists of three columns: Parameters (listing reference parameters for file selection), ECM Values (displaying current information in the ECM), and File Values (showing information of the file selected in the File Selection dialog box).

Finally, the Begin Flash button is available on this screen to initiate the flashing process. Also, note that the Browse Files… button allows you to view flash file information when a connection to an ECM has not been established through a data link connection or Trainer.

By following these instructions, you can effectively utilize the CAT Electronic Technician WinFlash function for setting up and programming ECMs.
