3. Fault Confirmation
__________________
A. Open the FWD cargo compartment door (referred to as cargo door) and look if the related green indicator light is on (Ref. AMM TASK 52-30-00-860-001).
4. Fault Isolation
_______________
A. If the operation shows that the green indicator light does not come on:
- press in the lamp (self-test of the lamp).
(1) If the green indicator light does not come on:
- do a check for 28 VDC between: the INDICATOR LIGHT FWD CARGO DOOR (9MJ) connectors 1 and 4 (Ref. ASM 52-35/01) or
(a) If there is 28 VDC:
- replace the INDICATOR LIGHT FWD CARGO DOOR (9MJ) (Ref. AMM TASK 52-35-12-000-001) and (Ref. AMM TASK 52-35-12-400-001).
(b) If there is no 28 VDC:
- do a check and repair the wiring between: the INDICATOR LIGHT FWD CARGO DOOR (9MJ) connector 4 and GND (Ref. ASM 52-35/01) or the INDICATOR LIGHT FWD CARGO DOOR (9MJ) connector 1 and CB (1MJ) (Ref. ASM 52-35/01).

(2) If the green the indicator light comes on:
- release the lamp and if the indicator light stays on (the proximity switches of the door actuators operate correctly) no further actions are necessary.
(3) If the indicator light goes off:
- do a check for 28 VDC between: the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connectors A/A and A/C (Ref. ASM 52-35/01)
(a) If there is no 28 VDC:
- do a check and repair the wiring between: the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connectors A/A and CB (1MJ) (Ref. ASM 52-35/01) or the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connectors A/C and GND (Ref. ASM 52-35/01)
(b) If there is 28 VDC:
- do a check for 28 VDC between: the SW ACTUATOR 2 FWD CARGO DOOR (2503MJ) connectors A/A and A/C (Ref. ASM 52-35/01)
1 if there is no 28 VDC:
_
- do a check for continuity between: the SW ACTUATOR 2 FWD CARGO DOOR (2503MJ) connector A/A and the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connector A/B (Ref. ASM 52-35/01).
a If there is continuity:
_
- make an electrical connection between: the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connectors A/A and A/B (Ref. ASM 52-35/01)
- do a check for 28 VDC between: the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) connectors A/B and A/C (Ref. ASM 52-35/01)
If there is 28 VDC:
replace the SW ACTUATOR 1 FWD CARGO DOOR (2502MJ) (Ref.
AMM TASK 52-36-18-000-002).
If there is no 28 VDC:
do a check and repair the wiring between:
the SW ACTUATOR 2 FWD CARGO DOOR (2503MJ) connector A/C
and GND (Ref. ASM 52-35/01).
2 If there is 28 VDC:
_
- make an electrical connection between: the SW ACTUATOR 2 FWD CARGO DOOR (2503MJ) connectors A/A and A/B (Ref. ASM 52-35/01)
- do a check for 28 VDC between: the SW ACTUATOR 2 FWD CARGO DOOR (2503MJ) connectors A/B and A/C (Ref. ASM 52-35/01)
