_______________
A. If the test gives the maintenance message ACSC1(47HH)/ACSC2(57HH) /WRG: ACSC1 BUSES TO ACSC2:
- do a check and repair the wiring (Ref. ASM 21-61/03) from:
- the ACSC1 (47HH) connector AA/5E to the ACSC2 (57HH) connector AA/3F,
- the ACSC1 (47HH) connector AA/5F to the ACSC2 (57HH) connector AA/3G,
- the ACSC1 (47HH) connector AA/6E to the ACSC2 (57HH) connector AA/4E,
- the ACSC1 (47HH) connector AA/6F to the ACSC2 (57HH) connector AA/4F.
(1) 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).
(2) 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).
B. Do the test as given in the Para. 3.A.
