DISC-FRICTION 2G0478 - Caterpillar

Use this procedure if the diagnostic code in Table 1 is active.
Table 1
Diagnostic Trouble Codes
J1939 Code and Description Conditions that Generate the Code System Response
630-2 Programmed Parameter Fault : Erratic, Intermittent, or Incorrect The Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed. The ECM may use a default torque map or the ECM may limit the engine to low idle.
The code remains active while the parameter is unprogrammed. The code will never be logged. 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 Power
This parameter specifies the rated power of the engine.Rated Peak Torque
This parameter specifies the rated peak torque of the engine.Test Spec
The test spec identifies the specific set of test specifications that are used to benchmark the performance of new
