a If there is 28VDC:
_
-do a check for ground at pin A/3 of the connector of the bleed pressure-regulator valve control-solenoid (10HA2).
If there is no ground signal:
* replace the SOLENOID-BLEED PRESS REG V CTL, ENG 2 (10HA2).
b If there is no 28VDC:
_
-do a check for 28VDC at pin A/D2 of the ENG 2 BLEED pushbutton switch (4HA2). . If there is 28VDC:
*
do a check and repair the wiring from the connector of the bleed pressure-regulator valve control-solenoid to the control-solenoid to the ENG 2 BLEED pushbutton switch, pin A/1 to pin A/D3.
If the fault continues:
*
replace the P/BSW-ENG 2 BLEED (4HA2). . If there is no 28VDC:
*
replace the circuit breaker (3HA2).
If the fault continues:
*
do a check and repair the wiring between the ENG 2 BLEED pushbutton switch to the circuit breaker (3HA2), pin A/D2 to pin 2.
C. If the test gives the maintenance message PRESS REG-V 4001HA2 OR SOL 10HA2 OR SENSE LINE:
-do the trouble shooting procedure for the Bleed Pressure Regulator Valve (4001HA) and the Bleed Pressure Regulator Solenoid (10HA2) (Ref. TSM TASK 36-11-00-810-830)
D. Do the test given in para. 3.

A. If the fault symptom is identified by the maintenance message: PRESS REG-V 4001HA1 OR HP BLEED-V 4000HA1 OR SENSE LINE and if the HP bleed valve is blocked in the open position:
-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 (Ref. ASM 36-11/01).
(a)
If the fault continues:
-replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
(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) and the HP bleed valve (4000HA)
(d)
If the fault continues:
-replace the VALVE-BLEED PRESS REG (4001HA) (Ref. AMM TASK 36-11-52-000-040) and (Ref. AMM TASK 36-11-52-400-040).
