(b)
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 and to the HP bleed valve closure control solenoid (11HA1).
2 Depressurize the system on the test set.
_
3 Remove the TEST SET - ENGINE BLEED SYSTEM (98D36003000000) or
_ TEST SET - ENGINE BLEED SYSTEM (98F36003002000).

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 at the bleed pressure-regulator valve (4001HA) and at the HP bleed valve (4000HA).
(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.
