(b) If there is no corrosion:
- dry the electrical connector of the N/W steering servo control
- make sure that the heat-shrink sleeve of the electrical connector is in good condition
- connect the electrical connector to the N/W steering servo control (6GC) and fold back the end of the heat-shrink sleeve on the connector to cover it fully.
(2) If there is no water:
- replace the SENSOR-N/W STRG FDBK,CTL CHAN (3GC) (Ref. AMM TASK 32-51-19-000-001) and (Ref. AMM TASK 32-51-19-400-001).
(3) If the fault continues:
- replace the BSCU (10GG) (Ref. AMM TASK 32-42-34-000-001) and (Ref. AMM TASK 32-42-34-400-001).
(4) 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).
(5) 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).
(6) 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).
(7) 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. If either the GND SCAN or the BITE test gives the maintenance message STEERING FEEDBACK CONTROL SENSOR (3GC):
- do a check for water (or moisture) in the electrical connector of the N/W steering servo control (6GC).
(1) If there is water:
- examine the electrical connector for corrosion
(a) If there is corrosion:
- replace the SERVO CTL-N/W STEERING (6GC) (Ref. AMM TASK 32-51-51-000-001) and (Ref. AMM TASK 32-51-51-400-001).
(b) If there is no corrosion:
- dry the electrical connector of the N/W steering servo control and connect it.
(2) If there is no water:
- replace the SENSOR-N/W STRG FDBK,CTL CHAN (3GC) (Ref. AMM TASK 32-51-19-000-001) and (Ref. AMM TASK 32-51-19-400-001).
(3) If the fault continues:
- replace the SENSOR-N/W STRG FDBK,MONITORING CHAN (4GC)
(4) If the fault continues:
- replace the BSCU (10GG) (Ref. AMM TASK 32-42-34-000-001) and (Ref. AMM TASK 32-42-34-400-001).
(5) 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).
(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 (4GC) pins AB/14E, 14F, 10E, 10F, 11F, 11E to pins A/A,B, C, D, E, F (Ref. ASM 32-51/01).
