AMM 73-21-60-000-001 Removal of the Electronic Control Unit (ECU)(4000KS) AMM 73-21-60-400-001 Installation of the Electronic Control Unit (ECU)(4000KS) AMM 73-29-00-710-040 Operational Test of the FADEC on the Ground (with Engine non Motoring)
3. Fault Confirmation
__________________
A. Do the operational test of the FADEC 1A 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 (NVM FAULT) is not confirmed:
- no maintenance action is required.
(2) If the failure message ECU (NVM 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 (NVM FAULT) is confirmed:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
R B. Do the test given in Para. 3.A.
R (1) No additional maintenance action is required if the fault is not R confirmed.
R (2) Repeat the fault isolation procedure if the fault continues.
