passwords may be used to protect customer parameters from being changed. Cat® Electronic Technician (ET) can be used to change certain parameters. There are some parameters that cannot be changed and there are some applications that do not allow any changes to the programmable monitoring system. The passwords are programmed into the Electronic Control Module (ECM) with Cat ET. One password may be programmed or both passwords may be programmed. If customer passwords are not programmed, customer parameters may be changed by anyone.To obtain customer passwords, contact the owner of the engine. If the owner has forgotten the customer passwords, factory passwords are used to create temporary customer passwords. Temporary customer passwords can be used to change the original customer passwords or any parameter that is protected by a customer password. When Cat ET is disconnected, you will be prompted to restore the original customer passwords. If the original passwords are not restored, the passwords will be changed to the temporary passwords.
