4. Fault Isolation
_______________
A. If the test gives a maintenance message, you can find the related trouble shooting procedure in the (Ref. TSM 36 PB 101).
(1) If there is no maintenance message:
-replace the VALVE-BLEED PRESS REG (4001HA) (Ref. AMM TASK 36-11-52-000-040) and (Ref. AMM TASK 36-11-52-400-040).
(a) If the fault continues:
-replace the SOLENOID-BLEED PRESS REG V CTL, ENG 1 (10HA1) (Ref. AMM TASK 36-11-55-000-001) and (Ref. AMM TASK 36-11-55-400-001).
1_ If the fault continues:
- replace the XDCR-BLEED TRANSFER PRESS, ENG 1 (7HA1) (Ref.
AMM TASK 36-11-15-000-001) and (Ref. AMM TASK 36-11-15-400-
001).
a If the fault continues:
_
-do a check and repair the wiring: . from the FULLY CLOSED signal of the BMC1 (1HA1) to the bleed pressure-regulator valve (4001HA) . from pin A/3 of the bleed pressure-regulator valve (4001HA) to the first terminal block (Ref. ASM 36-11/01).
B. After the subsequent flight, make sure that the fault does not continue.

4. Fault Isolation
_______________
A. If the test gives a maintenance message, you can find the related trouble shooting procedure in the (Ref. TSM 36 PB 101).
(1) If there is no maintenance message:
-do the functional test of the bleed transferred pressure transducer (7HA1) (Ref. AMM TASK 36-11-15-720-001).
(a)
If the test is not OK:
-replace the XDCR-BLEED TRANSFER PRESS, ENG 1 (7HA1) (Ref. AMM TASK 36-11-15-000-001) (Ref. AMM TASK 36-11-15-400-001).
(b)
If the test is OK:
-replace the VALVE-BLEED PRESS REG (4001HA) (Ref. AMM TASK 36-11-52-000-040) and (Ref. AMM TASK 36-11-52-400-040).
1_ If the fault continues:
- replace the SOLENOID-BLEED PRESS REG V CTL, ENG 1 (10HA1)
