3. Fault Confirmation
__________________
A. Test
(1) 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. If the test gives the maintenance message J3 (INSTINCT DISC):
- do a visual check of the connector J3 at the ECU (4000KS) for integrity (Ref. ASM 73-25/12).
(1) If the fault continues:
- do a check for open circuit at the harness J3 between pins 6 and
31.
(2) If the fault continues:
- replace the A/THR 1 relay (5CA1) (Ref. ASM 73-25/12).
(3) If the fault continues:
- replace the harness J3 (Ref. AMM TASK 71-51-43-000-044) and (Ref. AMM TASK 71-51-43-400-044).
