B. If on the ECAM BLEED page the pack 2 bypass valve shows AMBER XX:
- replace the VALVE-TURBINE BYPASS (30HH) (Ref. AMM TASK 21-61-53-000-001) and (Ref. AMM TASK 21-61-53-400-001).
(1) 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.

__________________
A. Test
(1) Do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001).
(2) Make sure that the pack 1 inlet-pressure indication on the ECAM BLEED page is > 20 PSI.
(3) Compare the PACK 1 & 2 outlet temperatures on the ECAM BLEED page during the next work step.
NOTE : PACK 1 & 2 outlet temperatures must be almost equal.
____
(4) On the AIR COND panel 30VU:
- put the COCKPIT, the FWD CABIN and the AFT CABIN selectors to the HOT position,
- wait for 10 minutes,
- put the COCKPIT, the FWD CABIN and the AFT CABIN selectors to the COLD position.
