Note: These diagnostic codes report the data link configuration status, but not the physical condition of the data link.

Possible FMI 11 causes are:

Configuration is not loaded
Incompatible or incorrect configuration loaded
Configuration loaded did not take effect when the ECM was not properly powered cycled

Possible FMI 14 causes are:

Incorrect personality module code
Invalid parameter configuration
Incorrect ECM

4. Check For an Associated FMI 9 Code A. Establish communication between Cat ET and the VIMS ECM. B. Check for an associated FMI 9 code.	Associated FMI 9 is not active	OK - Associated FMI 9 code is not active. Go to Step 5. Not OK - Associated FMI 9 code is active. Repair: A. Repair all associated FMI 9 codes. B. If an FMI 14 code is present after resolving the FMI 9 code, correct the FMI 14 code. STOP
5. Check the Personality Module Code for Compatibility With the Application A. Connect Cat ET. B. Select the ECM that is related to the code. C. Check the personality code.	Personality code is valid	OK - Personality code is valid. Go to Step 6. Not OK - Personality code is not valid. Repair: A. Obtain the correct flash file. B. Flash the ECM. C. Reset all active codes and clear all logged codes. Stop
6. Check the Configuration Parameters A. Connect Cat ET. B. Select "Configuration Parameters". C. Check the configuration parameters.	Configuration parameters are correct	OK - Configuration parameters are correct. Go to Step 7. Not OK - Configuration parameters are not correct. Repair: A. Program the parameters. B. Reset all active codes and clear all logged codes. Stop
7. Check For Compatibility With Other ECMs On the Data Link A. Connect Cat ET. B. Select the ECM that is related to the logged code. C. Determine if ECMs on the data link are compatible.	ECMs are compatible	OK - The ECMs are compatible. Repair: Contact your Technical Communicator. STOP Not OK - The ECMs are not compatible. Repair: A. Replace the incompatible ECM with the correct ECM.⁽¹⁾ B. Reset all active codes and clear all logged codes. Stop
