 3. Fault Confirmation
__________________
 A. Aircraft Maintenance Configuration
 (1) Open the FWD cargo compartment door (referred to as cargo door) in the normal mode (Ref. AMM TASK 52-30-00-860-001).
 NOTE : Make sure that a second person does not operate the AFT cargo
____
 door.

 (2) Open the AFT cargo door in the normal mode (Ref. AMM TASK 52-30-00-860-001).
 NOTE : Make sure that a second person does not operate the FWD cargo
____
 door.

 4. Fault Isolation
_______________
R **ON A/C 001-049, 101-105,
 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.
 (1) If there is no VDC:
 - do a check for 28VDC between the RELAY-TIME (6MJ) connector A/C1 and GND (Ref. ASM 52-35/01).
 (a) If there is 28 VDC:
 - do a check for 28 VDC between the RELAY-TIME (6MJ) connector A/X1 and GND (Ref. ASM 52-35/01).
 1 If there is no 28 VDC:
_
 - do a check and repair the wiring as necessary betwen: the RELAY-TIME (6MJ) connector A/X1 and the CB (1MJ) (Ref. ASM 52-35/01).
 2 If there is 28 VDC:
_
 - replace the RELAY-TIME (6MJ).
 (b) If there is no 28 VDC:
 - do a check for 28 VDC between: the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D1 and A/D2 (Ref. ASM 52-35/01).

 May 01/05 CES 1 If there is 28 VDC:

_
 - do a check for continuity: the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D1 and A/D2 (Ref. ASM 52-35/01).
 2 If there is continuity:
_
 - do a check and repair the wiring as necessary between: the RELAY-TIME (6MJ) connector A/C1 and the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D2 (Ref. ASM 52-35/01).
 3 If there is no continuity:
_
 - replace the RELAY-L/G POSITION, SYS 2 (12GB)
 4 If there is no 28 VDC:
_
 - do a check and repair the wiring as necessary between: the LGCIU-2 (5GA2) connector AA/8A and the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D1 (Ref. ASM 52-35/01).
 (2) If the fault continues:
 - do a check for a GND signal at the LGCIU-2 (5GA2) connector AA/9A (Ref. ASM 52-35/01).
 (a) If there is no GND signal:
 - do a check and repair each part of the wiring between the LGCIU-2 (5GA2) connector AA/9A and the connector A/A of 7550VC (Ref. ASM 52-35/01).
 1 If the fault continues:
_
 - do a check and repair the wiring between: the connector A/A of 7550VC and GND (Ref. ASM 52-35/01).
 (3) If the fault continues:
 - do a check for 28 VDC between: the LGCIU-2 (5GA2) connector AA/7A and GND (Ref. ASM 52-35/01).
 (a) If there are no 28 VDC:
 - do a check for continuity between: the MAN SEL VALVE-FWD CARGO DOOR (2501MJ) connector A/B and the LGCIU-2 (5GA2) connector AA/7A (Ref. ASM 52-35/01).
 1 If there is no continuity:
_
 - do a check and repair the wiring between: the MAN SEL VALVE-FWD CARGO DOOR (2501MJ) connector A/B and the LGCIU-2 (5GA2) connector AA/7A (Ref. ASM 52-35/01).
 2 If there is continuity:
_
 - do a check for 28 VDC between: the MAN SEL VALVE-FWD CARGO DOOR (2501MJ) connector A/A and GND (Ref. ASM 52-35/01).
