 A. On the MCDU 1, if the LAND TEST REFUSED message comes into view:
 - replace the FMGC-1 (1CA1) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
 (1) If the fault continues:
 - replace the LGCIU-1 (5GA1) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

 (2) If the fault continues:

 - replace the LGCIU-2 (5GA2) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

 (3) If the fault continues:

 - do a check of the wiring of the NOSE GEAR OWN discrete from the FMGC 1 (1CA1) to the LGCIU 1 (5GA1)

 - do a check of the wiring of the NOSE GEAR OPP discrete from the

 FMGC 1 (1CA1) to the LGCIU 2 (5GA2)
 (Ref. ASM 22-85/04).

 (a) If there is no continuity:

 - repair the above wiring.

 (b) If there is continuity:

 - do a check of the wiring of the ENG OWN STOP and ENG OPP STOP discretes (from the FMGC 1 (1CA1) to the diode module (1801VD)) (Ref. ASM 22-85/04).
 1 If there is no continuity:
_ - repair the above wiring.
 2 If there is continuity:
_
 - do a check of the wiring of the diode module 1801VD from pin A/10 and from pin A/11 to the first terminal block (Ref. ASM 22-85/04).
 a If there is no continuity:
_ - repair the above wiring.
 b If there is continuity:
_ - replace the DIODE MODULE (1801VD).
 B. Do the test given in Para. 3.
