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 AVSpare dealers.

In order to obtain the proper factory passwords, certain information must be given to an authorized AVSpare dealer. Since the factory passwords contain alphabetic characters, the AVSpare 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 is required to change the interlock code on a used Electronic Control Module (ECM). A new interlock code is also required to change the interlock code on a used 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.

Customer Passwords

Customer passwords allow the customer to restrict access to parameters that can be changed by the customer. The customer passwords cannot be longer than eight characters. The customer passwords may consist of alphanumeric characters. The customer has the option of entering one or two customer passwords.

If customer passwords have been entered, then the customer passwords are required to change any parameter that is customer programmable. Parameters that are customer programmable are those parameters that affect the engine speed limits and the power rating within an engine family. Refer to the diagnostic procedure Troubleshooting, "System Configuration Parameters" for more detail on parameters that are customer programmable.

Note: If the owner loses the owner's customer passwords, the owner will not be able to change parameters that are protected by customer passwords. You must use factory passwords in order to read the customer passwords. You may then use those customer passwords to change parameters that have been protected by customer passwords.
