 (a) If there is no GND signal:
 - do a check and repair the wiring between: the LGCIU-2 (5GA2) connector AA/9B and the connector A/A of 7552VC (Ref. ASM 52-35/01).

 (3) If the fault continues:

 - do a check for 28 VDC at: the LGCIU-2 (5GA2) connector AA/7B and GND (Ref. ASM 523501S01).
 (a) If there is no 28 VDC:
 - do a check for continuity between: the MAN SEL VALVE-AFT CARGO DOOR (2504MJ) connectors A/B and the LGCIU-2 (5GA2) connector AA/7B (Ref. ASM 52-35/01).
 1 If there is no continuity:
_
 - do a check and repair the wiring as necessary between: the MAN SEL VALVE-AFT CARGO DOOR (2504MJ) connectors A/B and LGCIU-2 (5GA2) connector AA/7B (Ref. ASM 52-35/01).
 2 If there is continuity:

_
 - replace the MAN SEL VALVE-AFT CARGO DOOR (2504MJ) (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 (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).

 (5) If the fault continues:

 - do the trouble shooting of the LGCIU-2 (5GA2) (Ref. TASK 32-31-00-810-802).

 - 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 2504MJ is
____ set to CLOSE during the fault isolation procedure.

 - 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:
