Troubleshooting Overview
Flash programming is a method of programming or updating the flash file in the Electronic Control Module (ECM). Cat® Electronic Technician (ET) is used to flash program a file into the memory of the ECM.Note: Customer versions of Cat ET do not have the capability for flash programming. Consult your local Cat Dealer for assistance.Use the "Flash File Search" tool on the Service Technician Workbench (STW) to obtain the flash file for your machine. Alternatively, use the "Service Software Files" feature on SIS Web to obtain the flash file for your machine. You must have the machine serial number to search for the flash file. After locating the correct flash file, download the flash file to your PC. Write down the name of the flash file for future reference.Troubleshooting Procedure

Troubleshooting Test Steps     Values     Results    
1. Programming a Flash File
A. Establish communication between Cat ET and the ECM.
B. Download an ECM replacement file. This file will help in the transfer of saved configurations for the Implement ECM and calibration values for solenoids and linkage sensors.
C. Select "WinFlash" from the "Utilities" menu on Cat ET.
If "WinFlash" will not communicate with the ECM, refer to Troubleshooting, UENR0515, "Electronic Service Tool Does Not Communicate".

E. Select the appropriate ECM under the "Detected ECM modules".
F. Press the "Browse" button to select the name of the flash file that will be programmed into the ECM.
G. When the correct flash file is selected, press the "Open" button.
H. Verify that the "File Values" match the application. If the "File Values" do not match the application, obtain the correct flash file.
J. When the correct flash file is selected, press the "Begin Flash" button.
K. Cat ET will indicate when flash programming has been successfully completed.
L. Start the machine and check for proper operation. Repair any active diagnostic or event codes.

NOT OK - The flash programming was not successful.
Repair: Repair any active diagnostic or event codes.
Proceed to Test Step 2.    
2. "WinFlash" Error Messages
A. If you receive any error messages during flash programming, click on the "Cancel" button 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 machine.
B. Record all error messages. The recorded error messages will be necessary if further assistance is needed.    
Error messages.     OK - There are no error messages. Return the unit to service.
STOP.
NOT OK - Error messages remain. Record all error messages.
Repair: If there are no active diagnostic or event codes and the proper flash file has been selected, the ECM may have failed. Prior to replacing an ECM, always contact the Technical Communicator for your dealership for possible consultation with Caterpillar®. This consultation may greatly reduce repair time.
