2 If the pressure decreases to "0" psig in less than 20 seconds:
_
-do an internal leakage check of the bleed pressure regulator valve control solenoid
-disconnect the sense line at the bleed pressure regulator valve control solenoid. Put a blanking cap on the sense line
-pressurize the sense line to 30 psi (2.0684 bar) then close the shut off valve of the pressure source.
a If the pressure decreases:
_ -repair or replace the sense line.
b If the pressure stays constant:
_
-replace the SOLENOID-BLEED PRESS REG V CTL, ENG 2 (10HA2) (Ref. AMM TASK 36-11-55-000-001) and (Ref. AMM TASK 36-11-55-400-001).
(3) If the fault continues:
-
do a check of the correct indication of the bleed regulated pressure transducer (8HA2)
- on the AIR control panel 30VU, push the APU BLEED pusbutton switch and set the X-BLEED selector switch to OPEN
-
do a check on the ECAM BLEED page of the pressure indications of the two systems.

(a) If the pressure indication of the defective system is 8 psi (0.5515 bar) minimum less than that of the opposite system:
-replace the XDCR-BLEED REGULATED PRESS, ENG 2 (8HA2) (Ref. AMM TASK 36-11-16-000-001) and (Ref. AMM TASK 36-11-16-400-001).
