94320 Mariner SCREW

System configuration parameters are parameters that are configured to specify the engine's emissions levels, the power rating, and the specific application. Default values for the parameters are programmed at the factory. Some parameters may be changed in order to equip the engine for a specific application. The system configuration parameters must be reprogrammed if the ECM is replaced. It is not necessary to reprogram the system configuration parameters if you update the ECM flash file. Also, certain configuration parameters are stamped into the engine information plate.Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.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
Rating Number
The rating number corresponds to the set of performance maps that has been selected for this application. The map is resident in the flash file for the engine.Rated Power
This parameter specifies the rated power of the engine.Rated Peak Torque
This parameter specifies the rated peak torque of the engine.Top Engine Speed Range
This parameter specifies the optimum top speed range of the engine.Test Spec
This is the engine's "Test Specifiction Number". Use this number to retrieve data that is related to the engine's specifications from the Technical Marketing Information System (TMI). The following information can be retrieved from TMI:
"As shipped consists"
"Engine test specifications"
"Systems data"
"Physical data"
"Gasket kit data"
"Reman parts"
"Performance data"A link to TMI Web can be found on the web site for the Service Information System (SIS).Equipment ID
This parameter allows the customer to enter a description into the ECM in order to identify the engine's application. A maximum of 17 characters can be entered in the field.Engine Serial Number
The engine serial number must be programmed to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed into a replacement ECM.ECM Serial Number
The serial number of the ECM that is stored in the ECM memorySoftware Group Part Number
The part number of the flash file that is currently installed in the ECMSoftware Group Release Date
The release date of the flash file that is currently installed in the ECMSoftware Group Description
The description of the application for the flash file that is currently installed in the ECMFLS
This parameter represents the fuel system adjustment 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.FTS
This parameter is another parameter that represents a fuel system adjustment that was performed at the factory in order to fine tune the fuel system. 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.Engine Fan Control
Set this parameter to "Installed" in order to configure the ECM for the installation of the cooling fan control solenoid.Engine Cooling Fan Maximum Pump Pressure
This parameter is used to adjust the maximum pump pressure of the engine cooling fan.Engine Cooling Fan Bypass System Installation Status
Set this parameter to "Installed" in order to configure the ECM for the installation of the cooling fan bypass valve.Engine Fan Reversing Feature
The Engine Fan Reversing Feature aids in clearing debris from the radiator.Engine Fan Manual Purge
The Engine Fan Manual Purge parameter enables manual operation of reverse fan function. The feature operates in neutral gear and in reverse gear.Engine Fan Suspend Purge
The Engine Fan Suspend Purge parameter enables automatic setting of the purge cycle.Engine Fan Reverse Solenoid
The Engine Fan Reverse Solenoid parameter enables operation of solenoid for reverse fan function.Engine Fan Reverse Switch
The Engine Fan Reverse Switch parameter enables operation of the switch for reverse fan function.Oil Renewal System Installation Status
Set this parameter to "Installed" in order to configure the ECM for the installation of the oil renewal system.Oil Renewal Control
Set this parameter to "Enabled" in order to configure the ECM for the oil renewal system.Oil Renewal Rate
This parameter sets the rate of injection of engine oil into the fuel system.Oil Renewal Level Switch Installation Status
Set this parameter to "Installed" in order to configure the ECM for the installation of the "oil renewal level switch".Ether Control
Set this parameter to "Enabled" in order to configure the ECM for the ether system.Engine Prelube Control
Set this parameter to "Installed" in order to configure the ECM for the installation of the prelube system.Engine Prelube Duration
This parameter sets the duration of the prelube cycle.
