Passwords
Passwords are part of a security system that helps to prevent unauthorized changing of certain parameters. Passwords prevent unauthorized erasing of logged events. Passwords allow the factory to control access to engine calibration parameters. Passwords allow the customer to control access to certain engine parameters.
Factory Passwords
Factory passwords are required to clear any event code. Factory passwords are required to change certain parameters such as "Full Load Setting". Factory passwords restrict changes to authorized personnel. When the correct factory passwords have been entered, the changes can then be made.
Note: Factory passwords are calculated on a computer system that is only available to Caterpillar dealers.
In order to obtain the proper factory passwords, certain information must be given to an authorized Caterpillar dealer. Since the factory passwords contain alphabetic characters, the Caterpillar Electronic Technician (ET) can be used to perform this function. In order to obtain the factory passwords, proceed as if you already have the factory passwords. At some point, if the factory passwords are actually needed, Cat ET will request the factory passwords and Cat ET will display the information that is required to obtain the factory passwords.
Note: The old interlock code and the new interlock code are required to change the interlock code on a used Electronic Control Module (ECM).
The Cat ET screen for factory passwords will display the following parameters:
- Serial number of the ECM
- Engine serial number
- Serial number for Cat ET
- Reason code
- Interlock code
- Total tattletale
Note: Factory passwords are only valid for the current Cat ET screen. A different set of factory passwords will be required if you exit the current Cat ET screen. A different set of passwords will be required to change information on another Cat ET screen.
