Troubleshooting Recommendations:

  1. Reset R IAPS Circuit Breaker CB2-B6. Is the fault message still present?

    1. If YES, continue with next step.
    2. If NO, do close out.
      NOTE: Before you open the IAPS circuit breakers, make sure that all Engine FADEC circuit breakers are open. If the Engine FADEC circuit breakers remain closed, Engine Igniters will activate. This can cause injury to persons and damage to equipment.

  2. Swap right FGC with left FGC. Is the fault message still present?

    1. If YES, continue with next step.
    2. If NO, replace defective FGC.

  3. Replace IAPS card cage (A4).
  4. Do close out.
