Troubleshooting Recommendations:

  1. Interchange the DCPC left microprocessors card with the right microprocessor card.

    1. If system checks are good, replace the defective DCPC microprocessor and do close out.
    2. If fault remains, continue with next step.

  2. On EMS CDU 1, perform a Virgin Start Procedure on the DCPC. DCPC component should be selected at step 4 to only perform the Virgin Start on this component.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  3. Replace DCPC supervisor card.
  4. Do close out.
