- FCV connector (8HB-A) pin D and the PC connector (27HH-AB) pin B6.
- FCV connector (8HB-A) pin B and GND (Ref. ASM 2151S01).
(6) Do a check for leakage at the cabin-pressure sense-line between FCV (11HB) and the pressurized area.
B. If the pack 1 flow indicator on the ECAM BLEED page is stuck in the low position:
NOTE : Do the following step only if the FCV is of the standard:
____
- PN 751A0000-07 Amdt. ABC or,
- PN 751A0000-07 Amdt. BC or,
- PN 751B0000-02 Amdt. ABC.
(1) Replace the VALVE-FLOW CTL (11HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).
(2) If the fault continues:
- do a leakage check of the sense-line between the FCW (11HB) and the pressure-sensor (10HB), and replace if necessary.
(3) If the fault continues:
- replace the SENSOR-PRESSURE (10HB) (Ref. AMM TASK 21-51-11-000-001) (Ref. AMM TASK 21-51-11-400-001)
(4) If the fault continues:
- do a leakage check of the sense-line between the CPNOH (10HM9) and the FCV (11HB), and replace if necessary.
(5) If the fault continues:
- replace the SENSOR-COMPRESSOR PNEUMATIC OVHT (10HM9) (Ref. AMM TASK 21-61-18-000-001) (Ref. AMM TASK 21-61-18-400-001)
(6) If the fault continues:
- Replace the REHEATER (10HM3) (Ref. AMM TASK 21-52-31-000-001) and (Ref. AMM TASK 21-52-31-400-001).

A. If the pack 1 flow indicator on the ECAM BLEED page is stuck in the high position:
(1) Replace the VALVE-FLOW CTL (8HB) of the opposite pack (pack 2) (Ref. AMM TASK 21-51-51-000-001) (Ref. AMM TASK 21-51-51-400-001).
(2) If the fault continues:
- do a leakage check of the sense line between the angled connector of the pressure-sensor(10HB) and the downstream pressure-port at the FCV (11HB), and replace if necessary.
(3) If the fault continues:
- replace the SENSOR-PRESSURE (10HB) (Ref. AMM TASK 21-51-11-000-001) (Ref. AMM TASK 21-51-11-400-001).
(4) If the fault continues:
