_
- replace the MAN SEL VALVE-FWD CARGO DOOR (2501MJ) (Ref. AMM TASK 52-36-15-000-001) and (Ref. AMM TASK 52-36-15-400-001).
(4) If the fault continues:
- make sure that the clearance between the target and the proximity sensor (SW-LOCKING SHAFT (5MJ)) is correctly adjusted (Ref. AMM TASK 52-35-13-400-002).
(a) If the fault continues:
- do the trouble shooting of the SW-LOCKING SHAFT (5MJ) (Ref. TASK 32-31-00-810-834)
(5) If the fault continues:
- do the trouble shooting of the LGCIU-2 (5GA2) (Ref. TASK 32-31-00-810-802).

A. If the fault confirmation gives that only the FWD cargo door does not open and the ELEC PUMP-Y (3075GX) does not operate (fault in the door control system):
- do a check for 28 VDC between: the RELAY-TIME (6MJ) connector A/B1 and GND (Ref. ASM 52-35/01).
NOTE : Make sure that the selector of the manual selector valve 2501MJ is
____ set to OPEN during the fault isolation procedure.
