Troubleshooting Recommendations:

  1. Perform wiring checks between EVSHC and ISU.

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Replace ISU.

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

  3. Replace EVSHC.

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

  4. Replace fairing.

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

  5. Replace IRW.
  6. Do close out.
