Factory passwords are also used to access specific configuration parameters in the Electronic Control Module (ECM). If you change parameters that require factory passwords, the "Enter Factory Passwords" dialog box will automatically be displayed. This dialog box indicates that a factory password must be obtained before the change can be made.A hyperlink is available at the bottom of the dialog box that will simplify the entry of ECM information into the FPS. To use this hyperlink, the Personal Computer (PC) that is running Cat ET must be connected to the Internet. When the hyperlink is selected, the ECM information will automatically be transferred to the entry screen on the Caterpillar FPS.If the PC that is running Cat ET is not connected to the Internet, you may save the ECM information to a file.
