If the unions are correct:
-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).

3. Fault Confirmation__________________
A. Test
(1) Do the BITE test of the BMC2 (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:
-do a check of the sense line unions at the bleed pressure-regulator valve of the engine 2 (4001HA) and the related control solenoid (10HA2).
(a)
If the unions are loose:
-tighten these unions again (specified torque value is 1.6 m.daN).
(b)
If the unions are correct:
-do the functional test of the upstream sense line between the bleed pressure-regulator valve (4001HA) and the control solenoid (10HA2) (Ref. AMM TASK 36-11-00-720-007).
