Troubleshooting Recommendations:

  1. Swap INBD WING AI TEMP SENSOR with OUTBD WING AI TEMP SENSOR.

    1. If system checks are good, replace INBD WING AI TEMP SENSOR and do close out.
    2. If fault remains, continue with next step.

  2. Perform wiring checks between BMC 2 and RIGHT INBD WING AI TEMP SENSOR.

    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.

  3. Replace BMC 2.
  4. Do close out.
