(5) If the fault continues:

 - do the trouble shooting of the LGCIU-2 (5GA2) (Ref. TASK 32-31-00-810-802).
 **ON A/C 001-003,
 B. If the test shows that the FWD cargo door does not move but the ELEC PUMP-Y (3075GX) operates (fault in the door hydraulic system): - operate the AFT cargo door (Ref. AMM TASK 52-30-00-860-001).
 (1) If the AFT cargo door moves:

 - 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).

 (3) If the AFT cargo door does not move:

 - open the FWD cargo door with the hand pump 3009GM (Ref. AMM TASK 52-30-00-860-003).
 (a) If the FWD cargo door opens:
 - do a check for 28 VDC between: the SEL VALVE-CARGO DOORS ELEC/MAN CTL (2500MJ) connector A/A and A/B (Ref. ASM 52-35/01).
