Flash Programming a Personality Module
Connect Cat ET to the service tool connector.
Select "WinFlash" from the "Utilities" menu on Cat ET. "WinFlash" will try to detect an ECM.Note: If "WinFlash" detects an ECM and "WinFlash" displays the ECM as "Unflashable", refer to Troubleshooting, "ATA (SAE J1587 / J1708) Data Link Circuit - Test".
When an ECM has been detected, the "ECM Selector" window will appear. Select the appropriate ECM that needs to be flashed and press "OK". The "Flash File Selection" window will appear.
The flash files are located on a disk drive and in a directory. Select the correct disk drive and the correct directory from "Drives" and "Directories" on Cat ET. A list of flash files will appear.
Select the correct file from the list of flash files. Read the "File Info" and the "Description" in order to verify that the correct file is selected. Select "OK".
Select the "Begin Flash" button in order to program the personality module. When the flash is completed, this message will appear: "Flash Completed Successfully".
Start the engine and check for proper operation.
If a diagnostic code of 268-02 is generated, program any parameters that were not in the old personality module.
Access the "Configuration" screen under the "Service" menu in order to determine the parameters that require programming. Look under the "Tattletale" column. All of the parameters should have a tattletale of one or more. If a parameter has a tattletale of zero, program that parameter. "WinFlash" Error Messages
