(5) If the fault continues:
- do a check and repair the wiring from the BSCU (10GG) to the feedback sensor (4GC) pins AB/14E, 14F, 10E, 10F, 11F, 11E to pins A/A, B, C, D, E, F (Ref. ASM 32-51/01).
(6) If the fault continues:
- do a check and repair the wiring from the BSCU (10GG) to the N/S steering servo control (6GC) pins AB/12E, 12F, 13E, 13F, 14E, 14F to pins A/G, H, E, F, C, D (Ref. ASM 32-51/01).
(7) If the fault continues:
- do a check and repair the wiring from the BSCU (10GG) to the feedback sensor (3GC) pins AB/15E, 15F, 8E, 8F, 9E, 9F to pins A/A, B, C, D, E, F (Ref. ASM 32-51/01).
(8) If the fault continues:
- do the check of the charge pressure of the nose landing gear shock absorber (Ref. AMM TASK 12-14-32-614-004)

__________________
A. Test Do the functional test of the nose wheel steering deactivation electrical box (Ref. AMM TASK 32-51-00-720-005).
4. Fault Isolation
_______________
A. If during the test, the N.WHEEL STEER DISC memo indication does not come into view on the upper ECAM DU:
- replace the ELEC BOX-N/W STEERING,DEACTIVATION (5GC) (Ref. AMM TASK 32-51-12-000-001) and (Ref. AMM TASK 32-51-12-400-001).
(1) If the fault continues:
- do a check for a ground signal at pin A/C of the electrical box (5GC) (Ref. ASM 32-51/01).
(a) If there is no ground signal:
- repair the wiring from the electrical box (5GC) pin A/C to the ground terminal (Ref. ASM 32-51/01).
