_______________
 A. If the test gives the maintenance message FCU, EIU (ATN1), J3:
 - do a check for open or short to ground at the harness J3 between the EIU (1KS1) and the ECU (4000KS) pins AB/5A, 5C to pins J3/22, 23 (Ref. ASM 73-25/06) and (Ref. ASM 73-25/10).
 (1) If the fault continues:

 - replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).

 (2) If the fault continues:

 - do a check of the wiring between the FCU (2CA) and the EIU (1KS1) pins AA/DD, EE to pins AA/1J, 1K.
 (a) If the wiring is not correct:

 - repair the above wiring.

 (b) If the wiring is correct:

 - replace the FCU (2CA) (Ref. AMM TASK 22-81-12-000-001) and (Ref. AMM TASK 22-81-12-400-001).

 (3) If the fault continues:

 - replace the FMGC (1CA1) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).

 (4) If the fault continues:

 - 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.
