3. Fault Confirmation
__________________
A. Test
(1) Do the pre-conditioning of the air conditioning system with the APU (Ref. AMM TASK 12-33-21-618-001)
(2) After approx. 4 minutes, stop the pre-conditioning.
NOTE : If a fault is detected, the ACSC1 gives a fault code for shop
____ maintenance in addition to the related CFDS message(s) (refer to TSM chapter 21-63-00, page block 301).
4. Fault Isolation
_______________
A. If the test gives the maintenance message,
P1 PR INL SENS(23HB1)/ P2 PRESS INL SENS(24HB1):
- replace the SENSOR-PRESS, PACK 1 INLET (23HB1) (Ref. AMM TASK 21-61-16-000-001) and (Ref. AMM TASK 21-61-16-400-002).

Aug 01/05 CES B. If the fault continues:
- replace the SENSOR-PRESS, PACK 2 INLET (24HB1) (Ref. AMM TASK 21-61-16-000-001) and (Ref. AMM TASK 21-61-16-400-002).
C. If the fault continues:
- replace the CONT-AIR COND SYSTEM 1 (47HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
(1) If the fault continues:
- replace the CONT-AIR COND SYSTEM 2 (57HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
D. If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/01) from:
- the PRESSURE SENSOR (23HB1) to the ACSC1 (47HH).
- do a check and repair the wiring (Ref. ASM 21-61/02) from:
- the PRESSURE SENSOR (24HB1) to the ACSC2 (57HH).
E. Do the test as given in the Para. 3.A.
