Troubleshooting Recommendations:

  1. Interchange microprocessor cards.

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

  2. On EMS CDU 1, perform Virgin Start Procedure on the ACPC assembly. ACPC component should be selected at step 4 from (virgin start procedure) 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 ACPC supervisor card.
  4. Do close out.
