4. Fault Isolation
_______________
A. If the isolation valve (33HN) does not operate and the FAULT legend on the pushbutton switch AFT ISOL VALVE, which is installed on the panel 22VU, comes on:
- do a check of the valve for damage (Ref. AMM TASK 21-28-52-000-001) and (Ref. AMM TASK 21-26-52-400-001).
(1) If the valve is damaged:
- replace the VALVE-ISOLATION, AFT CARGO COMPT (33HN) (referred to as VALVE (33HN)) (Ref. AMM TASK 21-28-52-000-001) and (Ref. AMM TASK 21-28-52-400-001).
(2) If the fault continues:
- replace the CONT-CARGO VENTILATION (10HN) (Ref. AMM TASK 21-28-34-000-001) and (Ref. AMM TASK 21-28-34-400-001).
(3) If the fault continues:
- do a check and repair the wiring between: VALVE (33HN) connector A/E and VC (10HN) connector B/X, VALVE (33HN) connector A/B and VC (10HN) connector B/Y, VALVE (33HN) connector A/A and VC (10HN) connector B/<B, VALVE (33HN) connector A/D and VC (10HN) connector B/<A, VALVE (33HN) connector A/F and GND, VALVE (33HN) connector A/C and GND (Ref. ASM 21-28/02).
