 A. Test
 (1) At the ADIRU 1 CDU, set the OFF/NAV/ATT selector switch to NAV.

 (2) At the MCDU, set the MENU MODE and get access to the SYSTEM REPORT/TEST F/CTL page (Ref. AMM TASK 31-32-00-860-006).

 (a) Get access to the SFCC 1 (2) SYSTEM DATA FLAP page and push the line key adjacent to the ARINC 429 INPUT STATUS indication:
 - if the ARINC input status shows ADIRU 1 LABEL *** NO DATA, do the Fault Isolation Procedure.

 4. Fault Isolation
_______________

 A. Procedure
 (1) Interchange the SFCC 1 (2) with SFCC 2 (1) (Ref. AMM TASK 27-51-34-000-001) (Ref. AMM TASK 27-51-34-400-001).

 (2) Do the test given in Para. 3.A:

 (a) If the fault does not continue, replace the initial SFCC-1 (21CV) (SFCC-2 (22CV)) (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

 (b) If the fault continues, replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).

 (3) Do the test given in Para. 3.A.

 - if the fault continues, do the next step.

 (4) Do a check and repair the aircraft wiring (Ref. ASM 27-51/08).

 (5) Do the test given in Para. 3.A.
