The efficient operation of an engine relies heavily on the correct programming of various parameters. When these parameters are erratic, intermittent, or incorrect, it can lead to performance issues and potential engine damage. Diagnostic Code SPN 630 – FMI 2, also known as Calibration Memory: Erratic, Intermittent, or Incorrect, is an indication that one or more programmable parameters have not been properly programmed.<\/p>\n

\"\"<\/a><\/p>\n

The Engine Electronic Control Module (ECM) is responsible for detecting these faults. In such cases, the ECM may resort to using default torque maps or limit the engine to low idle. It is important to note that this code is active only.<\/p>\n

To troubleshoot and resolve this issue, it is recommended to follow the outlined procedure:<\/strong><\/p>\n

1) Checking Programmable Configurations:<\/strong>
\nUpon detecting an unprogrammed parameter, the ECM generates the 268-2 or 630-2 Diagnostic Code. This code will identify the specific parameter that is not programmed. It is crucial to address these unprogrammed parameters as they can impact the engine’s performance and monitoring.<\/p>\n

\"\"<\/a><\/p>\n

To check the programmable configurations:
\nA) Connect to Caterpillar Electronic Technician (ET) software<\/a>.
\nB) Navigate to the Service tab.
\nC) Select the Configuration tab to view the Configuration Parameters.<\/p>\n

\"\"<\/a><\/p>\n

If an ECM replacement is required, the appropriate parameters must be copied from the old ECM using the “Copy Configuration” feature in CAT ET. Alternatively, the settings can be manually recorded and programmed into the new module’s configuration screen.<\/p>\n

2) Checking the Active Diagnostic Codes:<\/strong>
\nTo identify the specific parameters that are not programmed, follow these steps:
\nA) Select the Diagnostics tab in CAT ET<\/a>.
\nB) Access the Active Diagnostic Codes tab.<\/p>\n

\"\"<\/a><\/p>\n

This will provide a clear overview of the unprogrammed parameters and their impact on engine performance.<\/p>\n

3) Changing the System Settings (Configuration):<\/strong>
\nTo rectify the unprogrammed parameters, adjustments need to be made in the system settings:
\nA) Select the FLS or FTS tab. FLS stands for Full Load Setting, while FTS represents Full Torque Setting.
\nB) A warning message will appear; click OK to proceed.<\/p>\n

\"\"<\/a><\/p>\n

It is important to note that certain parameters may require customer or factory passwords for modification.<\/p>\n

C) Adjust the parameter values for FLS and FTS as necessary, then click OK.<\/p>\n

\"\"<\/a><\/p>\n

To access the correct parameter values for FLS and FTS, refer to the nameplate on the Caterpillar engine or consult the TMI web resources.<\/p>\n

D) A message box will appear, asking for confirmation to program the parameter. Click Yes to proceed.<\/p>\n

\"\"<\/a><\/p>\n

E) Once the changes are successfully implemented, the new values for FLS and FTS should be displayed.<\/p>\n

\"\"<\/a><\/p>\n

By following these troubleshooting steps and ensuring the correct programming of parameters, the Diagnostic Code SPN 630 – FMI 2 can be resolved, allowing the engine to function optimally. Regular monitoring and maintenance of these parameters are crucial to prevent further issues and ensure the longevity of the engine.<\/p>\n","protected":false},"excerpt":{"rendered":"
