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).

_______________
R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 301-399,
A. If the test gives the maintenance message P2 OUTLET TEMP SENSOR:
- replace the SENSOR-PACK OUTLET TEMPERATURE (34HH) (referred to as SENSOR (34HH)) (Ref. AMM TASK 21-61-15-000-001) and (Ref. AMM TASK 21-61-15-400-001).
(1) If the fault continues:
- do a check and repair the wiring between: SENSOR (34HH) connector A/C and PC 2 (27HH) connector AB/12A, SENSOR (34HH) connector A/B and PC 2 (27HH) connector AB/12B, SENSOR (34HH) connector A/A and PC 2 (27HH) connector AB/11D (Ref. ASM 21-61/02).
(2) If the fault continues:
- do a visiual inspection of the trim-air check-valve flappers (Ref. AMM TASK 21-63-42-210-001), and replace this valve if nessesary.
R **ON A/C 401-499,
A. If the test gives the maintenance message P2 OUT TEMP SENSOR(34HH):
- replace the SENSOR-PACK OUTLET TEMP (34HH) (Ref. AMM TASK 21-61-15-000-001) and (Ref. AMM TASK 21-61-15-400-001).
(1) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/02) from:
- the SENSOR (34HH) to the ACSC2 (57HH) and,
- the SENSOR (34HH) to ground.
(2) If the fault continues:
- do a visual inspection of the CHECK VALVE-TRIM AIR (19HM) flappers (Ref. AMM TASK 21-63-42-210-001), and replace this valve if nessesary.
**ON A/C ALL
B. Do the test as given in the Para. 3.A.
