If the position on the lower ECAM display unit is correct with the position indicator:
-connect the TEST SET - ENGINE BLEED SYSTEM (98D36003000000) or TEST SET - ENGINE BLEED SYSTEM (98F36003002000) to pressurize at 20 psi (1.3789 bar) the test port of the HP bleed valve.
1 Make sure that there are no leaks at the sense line between
_ the HP bleed valve and the bleed pressure regulator valve.
2 Depressurize the system on the test set.

A. If the fault symptom is identified by the maintenance message: HP BLEED-V 4000HA2 OR SENSE LINE
-do a check of the unions of the sense line from the bleed pressure-regulator valve (4001HA) and the HP bleed valve (4000HA) and to the HP bleed valve closure control solenoid (11HA2).
(1)
If the unions are loose:
-tighten these unions again (to 1.6 m.daN (11.79 lbf.ft)) and refer to Para. 4B.
(2)
If the unions are correct:
-make sure that the indication of the HP bleed valve position on the lower ECAM display unit is correct when you manually operate the valve shaft.
(a)
If the position on the lower ECAM display unit is different with the position indicator:
-replace the VALVE-HP BLEED (4000HA) (Ref. AMM TASK 36-11-51-000-040) and (Ref. AMM TASK 36-11-51-400-040).
(b)

-connect the TEST SET - ENGINE BLEED SYSTEM (98D36003000000) or TEST SET - ENGINE BLEED SYSTEM (98F36003002000) to pressurize at 20 psi (1.3789 bar) the test port of the HP Bleed valve.
1 Make sure that there are no leaks at the sense line between
_ the HP bleed valve and the bleed pressure regulator valve and to the HP bleed valve closure control solenoid (11HA2).
2 Depressurize the system on the test set.
