 (4) If the fault continues:

 - make sure that the clearance between the target and the proximity sensor (SW-LOCKING SHAFT (12MJ)) 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 (12MJ) (Ref. TASK 32-31-00-810-835).

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

 - open the AFT cargo door with the hand pump 3009GM (Ref. AMM TASK 52-30-00-860-003).
 (a) If the AFT 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).
 1 If there is 28 VDC:

 2 If there is no 28 VDC:
_
 - do a check and repair the wiring as necessary between: the SEL VALVE-CARGO DOORS ELEC/MAN CTL (2500MJ) connector A/A and the GND (Ref. ASM 52-35/01).
 3 If the fault continues:
_
 - do a check for 28 VDC between: the RELAY-TIME (6MJ) connector A/B1 and GND (Ref. ASM 52-35/01).
