| J1939 Code and Description | Conditions which Generate this Code | System Response |
| 630-2 Programmed Parameter Fault : 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. |
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 Caterpillar 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.
Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
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.
