do a check and repair the wiring between the ENG 1 BLEED pushbutton switch to the circuit breaker (3HA1), pin A/D2 to pin 2.
C. If the test gives the maintenance message: PRESS REG-V 4001HA1 OR SOL 10HA1 OR SENSE LINE
-do the trouble shooting procedure for the Bleed Pressure Regulator Valve (4001HA) and the Bleed Pressure Regulator Solenoid (10HA1) (Ref. TASK 36-11-00-810-829)
D. Do the test given in para. 3.

B. If the fault symptom is identified by the maintenance message:
PRESS REG-V 4001HA2 OR SOL 10HA2
-do a check of the visual position indicator of the bleed
pressure-regulator valve.
(1)
If the bleed pressure-regulator valve is 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).
(2)
If the bleed pressure-regulator valve is closed:
-make sure that the indication of the valve position on the lower ECAM display unit is correct when you manually operate the valve shaft.
(a) If the indication does not agree with the position of the valve butterfly:
1 Do a check and repair the wiring between the bleed pressure
_ regulator-valve (4001HA) to the BMC2 (1HA2), pin A/5 to pin AA/2B (Ref. ASM 36-11/02).
2 If the fault continues:
_
-replace the BMC-2 (1HA2) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
(b) If the fault continues:
-release the ENG 2 BLEED pushbutton switch
-make sure that the bleed pressure-regulator valve control-solenoid (10HA2) makes clicks.
1 If the solenoid makes clicks:
_
-do a check and clean the sense line between the bleed pressure-regulator valve control-solenoid (10HA2) and the bleed pressure-regulator valve (4001HA).
a If the fault continues:
_
-replace the VALVE-BLEED PRESS REG (4001HA).
b If the fault continues:
_
-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).
