844K and 854K Wheel Dozers and 990K, 992K, 993K, 994F and 994H Wheel Loaders Powered Access Stairway Caterpillar


MID 082 - CID 0800 - FMI 12

Usage:

854K 221
Conditions Which Generate This Code:


Illustration 1g01441590
Schematic of the Cat data Link

This diagnostic code is recorded when the Implement ECM can not communicate with the "VIMS" ECM. The Implement ECM and the "VIMS" ECM communicate via the CAT data link.

The possible causes for this diagnostic code are listed below:

  • The Implement ECM and the "VIMS" ECM are mismatched.

System Response:

The machine response is listed below:

  • The diagnostic code CID 0800 FMI 12 is active.

Note: Ensure that the diagnostic code indicator is active and that the diagnostic code is active.

Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS

  1. Verify that the following information is correct:

    • The part number of the flash software for the Implement ECM

    • The part number of the flash software for the "VIMS" ECM

    • The part number of the Implement ECM

    • The part number of the "VIMS" ECM

    Note: Consult your Caterpillar dealer for the correct part numbers of the flash software.

Expected Result:

All of the part numbers are correct.

Results:

  • OK - All of the part numbers are correct. The CID 0296 FMI 12 diagnostic code is active. The problem has not been corrected. The ECM may have corrupted software.

    Repair: Reflash the ECM with the correct software. See the Testing and Adjusting, "Electronic Control Module (ECM) - Flash Programming" section for additional information.

    STOP

  • NOT OK - All of the part numbers are not correct.

    Repair: The installed Implement ECM or the "VIMS" ECM have the wrong part number or the incorrect flash software is installed. Replace the incorrect Implement ECM or the "VIMS" ECM with a module that has the correct part number. Flash the correct software. See the Testing and Adjusting, "Electronic Control Module (ECM) - Flash Programming" section for additional information.

    STOP
