(1) Do the BITE test of the EFCS (Ground scanning) (system 2) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message IR1:
- replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(1) If the fault continues:
- remove the ADIRU 1
- do a check of the wiring between the ADIRU 1 and the first terminal block : for pins AB/5E, 6E of the ADIRU 1 (Ref. ASM 34-14/01)
(a) If the wiring is not ok:
- repair it
