System configuration parameters are parameters that affect emissions, power of the engine, and other features that define the characteristics of the engine subsystems. The parameters are preprogrammed at the factory. You may need to reprogram the system configuration parameters if the Electronic Control Module (ECM) is replaced and/or if you reprogram the engine rating. You do not need to reprogram the system configuration parameters if you replace the flash file. Caterpillar Electronic Technician (ET) can be used to view the values for these parameters at any time. Certain system configuration parameters are stamped on the engine information plate.Note: The unauthorized tampering with the parameters that are protected by factory passwords may cause your Caterpillar warranty to be voided.The system configuration parameters are listed in Table 2.

ECM Identification Parameters
Equipment ID
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the installation. A maximum of 17 characters may be entered in the field. This parameter is only for reference by the customer. This parameter is not required.Engine Serial Number
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate.Note: When you are requesting factory passwords, always use the engine serial number that is resident in the ECM.ECM Part Number
This parameter identifies the part number of the ECM.ECM Serial Number
The "ECM Serial Number" is stored in the memory of the ECM. The "ECM Serial Number" can be accessed by the use of Cat ET.Software Group Part Number
This parameter identifies the part number of the flash file that is currently installed in the ECM.Software Group Release Date
This parameter identifies the release date of the flash file that is currently installed in the ECM.Software Group Description
This parameter identifies the description of the application for the flash file that is currently installed in the ECM.Engine Configuration Parameters
Engine Fan Control
This parameter must be enabled, in order for the ECM to control the engine's fan.Maintenance Parameters
Maintenance Indicator Mode
The ECM records data that is related to equipment maintenance. The ECM will activate the maintenance indicator lamp when scheduled maintenance is due. The maintenance indicator lamp can be reset by actuating the maintenance clear switch. The maintenance interval may be based on operating hours or on fuel consumption. The ECM provides information that pertains to maintenance intervals and the last maintenance that was performed.Maintenance Level 1 Cycle Interval Hours
This parameter allows the customer to define the maintenance interval if "Maintenance Indicator Mode" is programmed to one of the manual options. Refer to the Operation and Maintenance Manual for more information.System Settings
Full Load Setting (FLS)
FLS is a parameter that represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information plate. Only change this value if the engine is rerated or if a new ECM has been installed. Factory passwords are required to change this parameter.Full Torque Setting (FTS)
FTS is similar to FLS. Only change this value if the engine is rerated or if a new ECM has been installed. Factory passwords are required to change this parameter.Parameter Worksheet
