Factory Passwords on Caterpillar ET Software

Programming Parameter

Cat ET can be used to view certain parameters that can affect the operation of the engine. The Cat ET can also be used to change certain parameters. The parameters are stored in the ECM. Some of the parameters are protected from unauthorized changes by passwords. Parameters that can be changed have a tattletale number. The tattletale number shows if a parameter has been changed.

Always document the parameters and the settings that are programmed into the engine control. A permanent record is essential when customer programmable parameters must be recovered.

Passwords
Passwords are part of a security system that helps to prevent unauthorized reprogramming 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 programmable engine parameters.


Customer Passwords
Customer Passwords allow the customer to restrict access to parameters that are programmable by the customer. The Customer Passwords cannot be longer than eight characters. The customer has the option of entering one or two Customer Passwords.
Figure 1.2 - Customer (Security) C-15
NOTE: If the owner loses the owner Customer Passwords, the owner will not be able to program parameters that are protected by Customer Passwords. Customer Passwords can be read if a factory password is obtained. Use those customer passwords to program parameters that have been protected by the Customer Passwords. But usually, you can directly edit the parameter as range value (Security: Customer).

Reset/View Customer Passwords
The "Reset/View Passwords" function provides two randomly generated customer passwords. This function allows a service technician access to customer password-protected parameters without divulging the actual customer passwords, which may be the same for an entire fleet. The original passwords may be restored through the "Restore Passwords" function when the temporary random passwords are no longer needed.

Factory Passwords
Factory Passwords are required to clear any event code. Factory Passwords are required to change certain parameters such as full load setting (FLS). The Factory Passwords restrict changes to authorized personnel. When the correct Factory Passwords have been entered, the changes can then be made. 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, Cat ET can be used to perform this function. In order to obtain the Factory Passwords, proceed as if you already have the Factory Passwords. If the Factory Passwords are needed, Cat ET will request the Factory Passwords. Cat ET will display the information that is required to obtain the Factory Passwords (as Figure 1.1 above).
Figure 1.5 - Factory (Security) 3512B
NOTE: The old interlock code is required to change the interlock code on a used 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 (as Figure 1.10 below):
  • Serial Number of the ECM
  • Engine Serial Number
  • Serial Number for Cat ET
  • Reason Code
  • Total Tattletale Number
NOTE: The Factory Passwords may only be used for one programming session. A different set of factory passwords will be required after you exit the Cat ET screen. A different set of passwords will be required to change information on another Cat ET screen.
