EDGE-CUTTING 9W7043 - Caterpillar

Use this procedure if the diagnostic code in Table 1 is active.
Table 1
Diagnostic Codes Table
J1939 Code and Description Conditions which Generate this Code System Response
630-2
Calibration Memory : Erratic, Intermittent, or Incorrect The engine 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 is active only.
2452-13
Generator Total Real Power : Calibration Required The engine Electronic Control Module (ECM) detects that the primary (PWM signal) and the secondary (CAN) load feedback signal are more than 100 kW apart. The code is active only. Some system configuration parameters are configurable by the customer in order to suit the customer particular application. The configuration file contains all of the adjustable settings for the monitoring system. The engine is shipped from the factory with default values for these parameters. In most cases, the parameters will not need to be changed. The system configuration parameters must be reprogrammed if an ECM is replaced and/or the engine rating is reprogrammed. System configuration parameters will not need to be reprogrammed if the flash file is replaced. Proper values for these parameters are available on Cat Electronic Technician (ET). Certain configuration parameters are also stamped on the engine information plate.If the default settings for the parameters have been modified, there will be no record at the factory of the changes. These settings can be downloaded into a laptop computer and saved to a file. The customer can then use the file in order to ease the future replacement of the ECM.No password is required for programming a new ECM during the first 100 hours of service life. This 100 hour “free configuration” feature enables the customer to tailor some of the programmable setpoints to the requirements of the installation.If a programmable parameter has not been programmed, the ECM will generate a 630-2 diagnostic code. The unprogrammed parameters will be set to default. Certain aspects of the engine performance and engine monitoring may be affected. Program the missing parameter.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.Equipment ID
This parameter allows the customer to enter a description into the ECM in order to identify the engine 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
