A. APU Bleed-Air Pressure Check
(1) Do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001).
(2) Make sure that the APU bleed-air pressure is higher than 12 psi (0.8273 bar).
(3) Stop the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001).
(4) If the APU bleed-air pressure is lower than or equal to 12 psi R (0.8273 bar), do the trouble shooting of the APU (refer to the fault R symptom list / 49-OBSV, APU BLEED FAULT No, Low or Fluctuating APU R Bleed-Air Pressure) before you continue with the subsequent R procedure.

B. Test
(1) 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).
(2) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(3) Do a check that the pack 2 inlet-pressure indication on the ECAM BLEED page is > 20 PSI.
(4) Do a check of the pack 2 flow indicator, the compressor discharge and pack outlet temperature on the ECAM BLEED page.
(5) Do a check to see that there is airflow at the pack 2 ram-air outlet. R **ON A/C 401-499,

4. Fault Isolation
_______________
A. If the pack 2 inlet-pressure indication on the ECAM BLEED page is < 20 PSI:
- increase the pressure to > 25 PSI.

B. For a Compressor Discharge Overheat Condition:
(1) If you select on the panel 30VU low airflow and the pack 2 flow indicator on the ECAM BLEED page moves to the HI indication:
- replace the VALVE-FLOW CTL (8HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).
(2) If the fault continues:
- do a check that the resistance of the compressor temperature sensor (32HH) measured between connector A/A and A/B is in these limits (Ref. ASM 21-61/02):
