System configuration parameters are parameters that affect emissions, power of the engine, and machine applications. Default values for the parameters are programmed at the factory. Some parameters may be changed by the customer in order to suit the needs of the specific application. You must reprogram the system configuration parameters if the Electronic Control Module (ECM) is replaced and/or if you reprogram the engine rating. Values for these parameters are available on Caterpillar Electronic Technician (ET). Certain configuration parameters are also stamped on the engine information plate.Check Programmable Parameters (268-2)
If a programmable parameter has not been programmed, the ECM will generate a 268-2 Check Programmable Parameters diagnostic code. The unprogrammed parameters will be set to default. Certain aspects of the engine's performance and engine monitoring may be affected.If "Injector Trim" is displayed below a 268-2 diagnostic code on Cat ET, refer to Troubleshooting, "Injector Trim File - Install".Parameter Descriptions
"Equipment ID"
The "Equipment ID" parameter allows the customer to enter a description into the ECM in order to identify the machine. A maximum of 17 characters can be entered in the field."Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed on a replacement 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 the service tool."ECM Part Number"
The "ECM Part Number" is stored in the memory of the ECM. The "ECM Part Number" can be accessed by the use of the service tool."Software Group Part Number (Flash File)"
The part number of the flash file is programmed into the software."Software Group Release Date (Flash File)"
The release date of the flash file is programmed into the software."Software Group Description"
The "Software Group Description" lists the application."Ether Solenoid Configuration"
The parameter for the "Ether Solenoid Configuration" allows the ether solenoid to be installed or not installed."Engine Warmup Elevated Idle"
The "Engine Warmup Elevated Idle" parameter allows the operation of this feature to be enabled or disabled."Engine Retarder Enable Command"
The "Engine Retarder Enable Command" parameter allows the operation of this feature to be enabled or disabled."Security System Immobilizer Installation Status"
The "Security System Immobilizer Installation Status" allows the "security system immobilizer" to be installed or not installed."FLS" (Full Load Setting)
"FLS" is a number 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 is installed. The parameter allows one time of programming without a factory password. In order to change the "FLS" after the initial programming, factory passwords are required."FTS" (Full Torque Setting)
"FTS" is similar to "FLS". Only change this value if the engine is rerated or if a new ECM is installed. Factory passwords are required. A new ECM or a blank ECM allows one time of programming of the "FTS" without the use of factory passwords. In order to change the "FTS" after the initial programming, factory passwords are required."Injector Trim File"
This parameter is for the injector trim files that are associated with each injector. If an injector is replaced or if two injectors are exchanged between cylinders, the injector trim file for the injector must be programmed to the correct cylinder.Parameter Table
