Troubleshooting Recommendations:

  1. Swap DAU 4 with DAU 3.

    1. If system checks are good, replace DAU 4 and do close out.
    2. If fault remains, continue with next step.

  2. Swap BMC 2 with BMC 1.

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

  3. Perform wiring checks between BMC 2, DAU 4 and right outboard WAITS.

    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.

  4. Replace RIGHT OUTBD WING AI TEMP SENSOR.
  5. Do close out.
