Flash Programming
Software for the 777D Off Highway Truck is located in the Electronic Control Modules (ECM). In order to upgrade or change the current software, use the "FLASH" software program.
Perform the following procedures to flash program an ECM. The ECM is flashed in order to upgrade software. The ECM is flashed in order to load software into an ECM. Flash programming of an ECM must also be done if the ECM has been replaced. The Caterpillar Electronic Technician (ET) contains the program WinFlash. WinFlash is used to load software into the ECM. The following procedure is used in order to flash software into an ECM.
- Connect the 139-4166 Data Link Cable between the 7x-1700 Communication Adapter and the diagnostic connector of the machine.
- Use WinFlash to load the new software.
Note: The ECM will indicate that the ECM is "BLANK" if the ECM is blank or an unsuccessful "FLASH" was performed.
