A. Do the operational test of the pack temperature-control system (Ref. AMM TASK 21-61-00-710-001).
NOTE : If a fault is detected, the PC gives a fault code for shop
____ maintenance in addition to the related CFDS message(s) (refer to TSM chapter 21-63-00, page block 301).

A. If the test gives the maintenance message TEST FAILED with the fault code (6D):
- do a check for a ground signal at the PC 1 (7HH) connector AA/9B (Ref. ASM 21-61/03).
(1) If there is no ground signal:
- do the BITE test of the landing gear (Ref. AMM TASK 32-69-00-740-001).
(a) If the test gives a different maintenance message refer to the Fault Symptom List.
(b) If the fault continues:
- do a check and repair the wiring if necessary between: PC 1 (7HH) connector AA/9B and LGCIU 2 (5GA2) connector AB/G1 (Ref. ASM 21-61/03).
(2) If the fault continues:
- do a check and repair the wiring between: PC 1 (7HH) connector AB/6B and FCV (11HB) connector A/D, PC 1 (7HH) connector AA/1D and FCV (11HB) connector A/E, PC 1 (7HH) connector AA/1C and FCV (11HB) connector A/F, PC 1 (7HH) connector AA/1B and FCV (11HB) connector A/G, PC 1 (7HH) connector AA/1A and FCV (11HB) connector A/V, PC 1 (7HH) connector AA/11C and FCV (11HB) connector A/J, PC 1 (7HH) connector AA/11B and FCV (11HB) connector A/K, PC 1 (7HH) connector AA/11A and FCV (11HB) connector A/L (Ref. ASM 21-51/01).
B. If the test gives the maintenance message P1 CONT:
- replace the CONTROLLER-PACK 1 TEMP (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring if necessary between: PC 1 (7HH) connector AA/5A and CB (1HH), PC 1 (7HH) connector AA/5B and GND, PC 1 (7HH) connector AB/13D and CB (2HH),

PC 1 (7HH) connector AB/14A and GND (Ref. ASM 21-61/03).
(2) If the fault continues:
- do a check and repair if necessary the wiring of the signal: ARINC 429 XTR (P) from the ZC (8HK) to the PC 1 (7HH), ARINC 429 XTR (S) from the ZC (8HK) to the PC 1 (7HH), ARINC 429 RCV (S) from the ZC (8HK) to the PC 1 (7HH) (Ref. ASM 21-63/02).
(3) If the fault continues:
- do the trouble shooting procedures for the pack 1 electrical component with short circuit (Ref. TASK 21-61-00-810-820).
R **ON A/C 401-499,
B. If the test gives the maintenance message ACSC1 (47HH):
- 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).
