 A. Do the operational test of the FADEC 2B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
 4. Fault Isolation
_______________
 A. This failure message is generated when there is an internal ECU
 processing fault.

 (1) If the failure message ECU (CPU FAULT) is not confirmed:

 - no maintenance action is required.

 (2) If the failure message ECU (CPU FAULT) is not confirmed, but is repetitive:

 - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).

 (3) If the failure message ECU (CPU FAULT) is confirmed:

 - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
 B. Do the test given in Para. 3.A.
 (1) No additional maintenance action is required if the fault is not confirmed.

 (2) Repeat the fault isolation procedure if the fault continues.
