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.To obtain the flash file, use the "Flash File Search" tool on the Service Technician Workbench (STW) to obtain the machine flash file. 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.Programming Procedure
