(b)
If the fault continues:
-replace the VALVE-HP BLEED (4000HA) (Ref. AMM TASK 36-11-51-000-040) and (Ref. AMM TASK 36-11-51-400-040).
(c)
If the fault continues:
-do a check and clean the sense line between the bleed pressure-regulator valve (4001HA), the HP bleed valve (4000HA) and the associated solenoid (11HA2).

A. If the fault symptom is identified by the maintenance message:
HP BLEED-V 4000HA1
-make sure that the indication of the position of the HP bleed valve on the lower ECAM display unit is correct when you manually operate the valve shaft.
(1) If the indication does not agree with the position of the valve butterfly:
-do a check and repair the wiring from the HP bleed valve to the BMC1, pin A/1 to pin AA/14A and pin A/5 to pin AA/15A (Ref. ASM 36-11/01).

If the fault continues:
-do a check and repair the wiring between pin A/3 of the HP bleed valve and the ground terminal.
