3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the avionics equipment ventilation from the Multipurpose Control and Display Unit (MCDU) (Ref. AMM TASK 21-26-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message PRESSURE SW 30HQ:
- replace the PRESS SW-EXTRACT FAN, AVNCS VENT (30HQ) (Ref. AMM TASK 21-26-11-000-001) and (Ref. AMM TASK 21-26-11-400-001).
(1) If the fault continues:
- do a check and repair the wiring between the AEVC (10HQ) and the extract fan pressure switch (30HQ), pins AB/8B and pins A/A (Ref. ASM 21-26/02).
(a) If the fault continues:
- replace the AEVC (10HQ) (Ref. AMM TASK 21-26-34-000-001) (Ref. AMM TASK 21-26-34-400-001).
