Programmable Parameters
Many programmable parameters affect engine operation. Certain parameters affecting Marine Engine operation may be changed with an Electronic Service Tool. Some parameters may affect engine operation in ways an operator does not expect. Without adequate training, these parameters may lead to power or performance complaints, even when the engine is performing to specification.The parameters are stored in the ECM, and are protected from unauthorized changes by passwords. These parameters are either System Configuration Parameters or Customer Specified Parameters. Any parameter can be read, however, passwords protect parameters from unauthorized changes.Two categories contain various parameters, System Configuration Parameters and Customer Specified Parameters. System Configuration Parameters can be altered only with the proper factory passwords using an Electronic Control Analyzer & Programmer (ECAP) or Caterpillar Electronic Technician (ET). Customer Specified Parameters can be changed using an Electronic Service Tool only with the proper customer passwords.Refer to the topics, Passwords, System Configuration Parameters and Customer Specified Parameters for more details on how to receive and use factory passwords and customer passwords. System Configuration Parameters are set at the factory and affect emissions or power ratings within a family of engines. Factory passwords must be obtained and used to change System Configuration Parameters. Customer Specified Parameters are variable and can be used to affect engine rpm limits, rpm/power ratings within the limits set by the factory and Caterpillar Engine Monitoring. Customer passwords are necessary to change Customer Specified Parameters.System Configuration Parameters
System Configuration Parameters affect emissions or power of the engine. They are programmed at the factory and would normally never need to be changed through the life of the engine. System Configuration Parameters must be reprogrammed if an ECM is replaced. Proper values for these parameters are stamped on the Engine Information Plate. The following is a description of the System Configuration Parameters.Full Load Setting
The setting number represents the fuel system adjustment performed at the factory to fine tune the fuel system. A new ECM must have this parameter programmed to avoid generating a Diagnostic Code 253-02 Check Customer Or System Parameters (56).Full Torque Setting
Similar to Full Load Setting this parameter is programmed at the factory. Factory level passwords are required to change the Full Torque Setting. A new ECM must have this parameter programmed to avoid generating a Diagnostic Code 253-02 Check Customer Or System Parameters (56).Personality Module Code
Code which prevents use of incorrect Personality Module for this engine. Each power family has a different code associated with it.When a Personality Module is replaced, this code (stored in the ECM) must match the one in the introduced Personality Module or the engine will only run at low idle and a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will also be generated.When rerating the engine, programming this code to "0" will prompt the ECM to read and match its stored code to the Personality Module Code.Engine Serial Number
The engine serial number should be programmed to match the engine serial number stamped on the Engine Information Plate. A new ECM
