- swap back the ACSC2 (57HH) and replace the CONT-AIR COND SYSTEM 1 (47HH) (ACSC1 47HH).
(2) If the fault does not move with the ACSC1:
- swap back the ACSC1 (47HH) and the ACSC2 (57HH).
- replace the VALVE-TURBINE BYPASS (10HH) (Ref. AMM TASK 21-61-53-000-001) and (Ref. AMM TASK 21-61-53-400-001).

Aug 01/05 CES (3) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/01) from:
- the VALVE (10HH) to the ACSC1 (47HH) and,
- the VALVE (10HH) to ground.
B. Put the aircraft back to its initial configuration.

A. Do the operational test of the pack temperature-control system (Ref. AMM TASK 21-61-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ACSC2(57HH)/P2 BYPASS
VALVE(30HH):
- swap the ACSC2 (57HH) and the ACSC1 (47HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
(1) If the fault moves with the ACSC2:
- swap back the ACSC1 (57HH) and replace the CONT-AIR COND SYSTEM 2 (57HH) (ACSC2 57HH).
(2) If the fault does not move with the ACSC2:
- swap back the ACSC2 (47HH) and the ACSC1 (57HH).
- replace the VALVE-TURBINE BYPASS (30HH) (Ref. AMM TASK 21-61-53-000-001) and (Ref. AMM TASK 21-61-53-400-001).
(3) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/02) from:
- the VALVE (30HH) to the ACSC2 (57HH) and,
- the VALVE (30HH) to ground.
B. Do the test as given in the PARA. 3.A.

A. Access
(1) Get access to the heat exchanger areas for both packs.
B. Test NOTE : The fault indications cannot be reproduced on the ground.
____
(1) Do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001).
4. Fault Isolation
_______________
A. Leak Check
(1) In each heat exchanger unit area do a check for hot air leaks at:
- the duct connections, the welded joints and all component surfaces.
(2) Leaks must be removed either by replacement of the applicable seals or by replacement of the faulty component.
