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, but not if the Personality Module is replaced (unless the engine rating changes). Proper values for these parameters are stamped on the engine information ratings plate located on the valve cover or intake manifold. Factory Passwords are required to change these parameters. The following is a description of the System Configuration Parameters.Full Load Setting (FLS)
Number representing fuel system adjustment made at the factory to "fine tune" the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. 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 (FTS)
Similar to Full Load Setting. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Personality Module Code
Code which prevents use of incorrect personality module for this engine. Each power family and emission certification has a different code associated with it.When a personality module is replaced (flash programmed), 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. This code does not need to be programmed when a personality module is replaced, as long as the new module is of the same family and emission year.If the Personality Module is of a different family, then pistons, injectors, etc, may need to be changed and the engine information plate must also be changed to reflect the new rating.Some vehicle systems, such as the cooling system or transmission may also require changes when uprating an engine. Please contact the local OEM dealer for further information.Engine Serial Number
Should be programmed to match the engine serial number stamped on the ratings plate. A new ECM is delivered without the engine serial number programmed.Personality Module Release Date
This parameter is defined by the Personality Module and is not programmable. It is used to provide the version of the software. Customer parameters and software changes can be tracked by this date. The date is provided in month and year (NOV99), where NOV is the month (November) and 99 is the year (1999).Customer Specified Parameters
Customer Specified Parameters allow the truck owner to influence how a driver operates the vehicle. Some parameters may affect engine operation in ways an inadequately trained driver does not expect. These parameters may lead to power or performance complaints, even when the engine is performing to specification.Customer parameters may be changed repeatedly as a customer changes his operation or as new drivers are assigned to a truck. Customer Passwords are required to change these parameters.The following is a brief description of the Customer Specified Parameters. Along with each are the minimum and maximum values for the parameter and the default value. Parameter value shown in bold is programmed setting to disable a feature.The tables show values in an approximate range for metric (kilometers, km/h, liters) units, followed by its U.S. (or English) (miles, mph, quarts) units counterpart. The exact range of the parameter in metric units depends upon the Service Tool used because each Tool may use slightly different conversion factors.Customer Parameter Lockout
This feature restricts access to changing some available parameters. Locking out a parameter requires Customer Passwords (if used). Once a parameter is locked out, Factory Passwords are required to change the parameter or unlock the parameter.If a "lockable" parameter is not locked out, Factory Passwords are not required to change or lock the parameter. A locked out parameter restricts the parameter from being changed directly by the customer. This helps vehicle owners encountering problems with operators obtaining Customer Passwords and altering some of these parameters. It also provides a trail to determine who changed the parameter and when.The following Customer Parameters are available for Lockout.* Vehicle Speed Limit* VSL Protection* High Cruise Control Speed Set Limit* Top Engine Limit* Transmission Style* Soft Vehicle Speed Limit* A/C Switch Fan-On Time* Low Speed Range Axle Ratio* High Speed Range Axle Ratio* Top Gear Ratio* Top Gear Minus One Ratio* Top Gear Minus Two Ratio* Vehicle Speed Calibration* Engine Retarder Delay* Fan Control Type* Driver Reward EnableWhen an attempt to change a locked out parameter occurs, the Electronic Service Tool will indicate the parameter is locked. Go to the Parameter Lockout screen to Unlock the parameter.Factory Passwords are required to change a parameter from "locked" to "unlocked". If more than one parameter is locked out, and each one needs to be unlocked, only one Factory Password is required.Selected Engine Rating
Rating Number
The Rating Number is the selected rating used within a power family. The Personality Module defines the power family (such as 325 hp, [242 kW]) and may contain only one or several ratings. The rating number defines which rating is used (such as 435 hp [324 kW] Governed Speed 1800 rpm or 435 hp [324 kW] Governed Speed 2100 rpm) within the family. Both ratings will be displayed for Multi-Torque applications.ECM Identification Parameters
Vehicle ID
Identification of the vehicle assigned by the customer and used only for customer reference. Not required by the ECM.Security Access Parameters
ECM Wireless Communication Enable
This parameter determines if the ECM will transfer information over the data link through remote communications systems for customers.The parameter will default out of Caterpillar to no access. It can only be enabled by getting Factory Passwords. This feature can only be enabled after the truck has been delivered to the customer. For more information refer to "Wireless Communication Enable" on page 15.Vehicle Speed Parameters
Vehicle Speed Calibration
The ECM uses this value to scale the vehicle
