858697A 4 Mercury FUEL LINE (Original Equipment)

If a programmable parameter has not been programmed, the ECM will generate a 630-2 diagnostic code. The parameter that is not programmed will be listed under the code. The unprogrammed parameters will be set to default. Certain aspects of the engine performance and engine monitoring may be affected.If "Injector Trim" is displayed below a 630-2 diagnostic code on Caterpillar Electronic Technician (ET), refer to Troubleshooting, "Injector Trim File - Install".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 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. Cat ET can be used to view the values for these parameters. Certain system configuration parameters are stamped on the engine information plate.Parameter Descriptions
ECM Identification Parameters
Equipment ID
This parameter 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 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.Selected Engine Rating
Rating Number
The rating number corresponds to the selected set of performance maps that has been selected for this application. There may be more than one set of performance maps that are available for this engine. All of the maps are resident in the flash file for the engine.Rated Frequency
The line frequency of the generator setRated Engine Speed
The optimum speed of the engineRated Real Genset Power
The output power of the generator set in kilowattsRated Apparent Genset Power
The kVA rating of the generator setRating Configuration
The performance maps in the softwareTest Spec
The test spec identifies the specific set of test specifications that are used to benchmark the performance of new engines in the test cell. Use this number to retrieve data that is related to the engine 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 can be found on the web site for the Service Information System (SIS).Engine/Gear Parameters
Engine Acceleration Rate
This parameter defines the maximum rate of engine acceleration.Engine State Control Input Configuration
This parameter identifies the type of external source that is used by the ECM in order to obtain command signals for the engine state control.Cooldown Speed
This parameter defines the engine rpm during the cooldown period.Cooldown Duration
This parameter defines the duration of engine operation at the cooldown speed. Programming this parameter to 0 will disable this function.Low Idle Speed
This parameter defines the low idle rpm of the engine.Engine Speed Droop
This parameter enables the engine to be operated in a load sharing system.Crank Terminate rpm
This parameter defines the engine speed that must be achieved to terminate cranking of the engine for start-up.Engine Pre-Lube Duration
This parameter configures the actual duration for the activation of the prelubrication pump.Engine Pre-Lube
Programming this parameter to "Enabled" allows pre-lubrication prior to start up. Programming this parameter to "Disabled" will disable the function. Program this parameter to "Disabled" if the function is not being used or if prelube is not installed on this engine. Programming this parameter to "Disabled" will prevent diagnostics from being logged.Crank Duration
This parameter defines the maximum amount of time for an attempt to start the engine. During a single attempt, the ECM will activate the starting motor for no longer than the duration that is defined in this parameter.Maximum Number of Crank Cycles
This parameter defines the total number of crank cycles that are performed by the starting system during an attempt to start the engine. An overcrank fault is logged if the engine does not start.Droop Mode Selection
This parameter allows the customer to select the droop mode or the isochronous mode.I/O Configuration Parameters
