_______________
A. If the POST FLIGHT REPORT shows the warning AIR COND CTL 2-B FAULT
without any associated maintenance messages:
(1) Do a check of the wiring (Ref. ASM 216101S1) from,
- the ACSC2 (57HH/C) pin 2 to the CB (56HH) (28VDC supply) and,
- the ACSC2 (57HH/C) pin 1 to the CB (54HH) (115VAC supply). 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).

_______________
A. If the test does not confirm the fault:
(1) Do the reset procedure for the ACSC1 as follows, - open the circuit breakers 49HH, 50HH, 51HH and 52HH.
- wait for a minimum of 5 seconds.
- close the circuit breakers 49HH, 50HH, 51HH and 52HH.
(2) No further trouble shooting is necessary.
B. If on the ECAM BLEED page the pack 1 bypass valve shows AMBER XX:
- replace the VALVE-TURBINE BYPASS (10HH) (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 21-61/04) from:
- the VALVE (10HH) to the ACSC1 (47HH) and,
- the VALVE (10HH) to ground.
