Aircrew shall not use the ____________________ if a Level 1 FADEC failure is noted.

Explanation:
In a Level 1 FADEC fault, you must not engage the training (TRNG) switch because this mode is intended for ground testing or fault simulation and bypasses normal FADEC protection and diagnostic logic. Activating it during an actual FADEC fault can mask the problem or push the engine beyond safe limits, compromising control and safety. The other interfaces—DECU, CSYNC, and BIM—are part of the FADEC system’s normal operation or fault-management pathways and are not indicated as prohibited in this situation. Rely on the degraded FADEC procedures and standard backup paths to maintain safe engine operation.
