__________________
A. Test
(1) Do the operational test of the automatic braking when the landing gear is retracted (Ref. AMM TASK 32-42-00-710-004).
(2) Make sure that the brake unit pistons do not come out of their housings.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- replace the LEVER-L/G NORM CTL (6GA) (Ref. AMM TASK 32-31-11-000-001) and (Ref. AMM TASK 32-31-11-400-001).
(1) 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).

(2) If the fault continues:
- do a check for a ground signal at the L/G Normal control lever (6GA) pin A/H (Ref. ASM 32-42/01).
(a) If there is a ground signal:
- do a check and repair the wiring from the L/G Normal control lever (6GA) to the BSCU (10GG) pin A/B to pin AA/12E.
(b) If there is no ground signal:
- repair the wiring from the L/G Normal control lever (6GA) pin A/H to the ground terminal.
