_
 -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 1 (10HA1) (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 (8HA1)

 - 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 1 (8HA1) (Ref. AMM TASK 36-11-16-000-001) and (Ref. AMM TASK 36-11-16-400-001).

 4. Fault Isolation_______________
 A. If the fault is identified by the maintenance message:
 PRESS REG-V 4001HA2 or SOL 10HA2 or SENSE LINE

 -do a check of the sense line unions and clamps between the bleed pressure regulator valve (4001HA) and the solenoid (10HA2).
 (1) If the unions are loose:
 -tighten them.

 (2) If the unions are correctly tightened:
 -do a check of the opening of the bleed pressure regulator valve
 -disconnect the sense line between the bleed pressure regulator valve and the bleed pressure regulator valve control solenoid at the bleed pressure regulator valve. Put a blanking cap on the union of the pressure regulator valve.
 -do a check of the opening of the bleed pressure regulator valve. Apply 20 psi (1.3789 bar) at its test port. The visual indicator must show that the bleed pressure regulator valve is fully open.
 (a)
 If the bleed pressure regulator valve does not open:

 -replace the VALVE-BLEED PRESS REG (4001HA) (Ref. AMM TASK 36-11-52-000-040) and (Ref. AMM TASK 36-11-52-400-040).

 (b)
 If the bleed pressure regulator valve opens:

 -do a leakage check of the sense line between the bleed pressure regulator valve and the bleed pressure regulator valve control solenoid. Pressurize the sense line of the bleed pressure regulator valve and its related solenoid to 30 psi (2.0684 bar) and close the shut-off valve of the pressure source.
 1_ If the pressure decreases very slowly:
 - replace the VALVE-BLEED PRESS REG (4001HA) (Ref. AMM TASK
