- the ACSC2 (57HH) connector AA/5F to the ACSC1 (47HH) connector AA/3G.
(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).
(2) 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).
B. Do the test as given in the Para. 3.A.
