Flash Programming - This is a method of programming or updating the personality module in an Electronic Control Module (ECM).
The Caterpillar Electronic Technician (ET) can be utilized to flash a new personality module into the ECM. The flash is accomplished by transferring the data from a PC to the ECM.
Flash Programming a Personality Module
- Obtain the part number for the new flash file.
- If the part number is not available, use the "Flash File Search" tool on the Service Technician Workbench (STW) or on SIS Web.
Note: The engine serial number must be obtained in order to use the "Flash File Search".
- If the part number is not available, use the "Flash File Search" tool on the Service Technician Workbench (STW) or on SIS Web.
- Connect Cat ET to the service tool connector.
- Turn the keyswitch to the ON position. Do not start the engine.
- Select "WinFlash" from the "Utilities" menu on Cat ET.
Note: If "WinFlash" will not communicate with the ECM, refer to the diagnostic procedure Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM".
- Program the flash file into the ECM.
- Select the engine ECM under the "Detected ECMs".
- Press the "Browse" button in order to select the part number of the flash file that will be programmed into the ECM.
- When the correct flash file is selected, press the "Open" button.
- Verify that the "File Values" match the application. If the "File Values" do not match the application, search for the correct flash file.
- When the correct flash file is selected, press the "Begin Flash" button.
- Cat ET will indicate when flash programming has been successfully completed.
- Start the engine and check for proper operation.
- If a diagnostic code of 268-02 "Check Programmable Parameters" 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 1 or more. If a parameter has a tattletale of 0, program that parameter.
"WinFlash" Error Messages
If you receive any error messages during flash programming, click on the "Cancel" button in order to stop the process. Access the information about the "ECM Summary" under the "Information" menu. Make sure that you are flashing the correct file for your engine.
