a If the fault continues:
_
-do the functional test of the upstream sense line between the bleed pressure-regulator valve (4001HA) and the control solenoid (10HA1) (Ref. AMM TASK 36-11-00-720-007).
*
If the pressure decreases to 0 psig in less than 20
seconds:
** replace the related sense line.
*
If the pressure drop is not high:
** 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/5 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.

(1) Do the BITE test of the BMC1 (Ref. AMM TASK 36-11-00-740-001).
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-HP BLEED (4000HA) (Ref. AMM TASK 36-11-51-000-040) and (Ref. AMM TASK 36-11-51-400-040).
(a) If the fault continues:
-do the functional test of the upstream sense line between the bleed pressure-regulator valve (4001HA) and the control solenoid (10HA1) (Ref. AMM TASK 36-11-00-720-007).
