 d If the pressure in the reservoir does not increase to the_
 necessary value:
 - remove the RESTRICTOR- RSVR PRESS, ENG 1 BLEED (1392GM)
 (Ref. AMM TASK 29-14-13-000-001).
 - make sure that the RESTRICTOR- RSVR PRESS, ENG 1 BLEED
 (1392GM) and the filter are not clogged or damaged.
 - if necessary, replace the RESTRICTOR- RSVR PRESS, ENG 1
 BLEED (1392GM) (Ref. AMM TASK 29-14-13-400-001).
 e If the fault continues:_
 - do a check and, if necessary, repair the bleed air line 
R  in the left pylon to the reservoir pressurization unit 
R  (1360GM).
 f If the fault continues:_
 - do a check and, if necessary, repair the remaining bleed
 air lines and components.

 g Stop the pressurization of the reservoir pressurization_
 system from the left engine (Ref. AMM TASK 29-14-00-720-
002), or
 h Disconnect the external pressure source:_
 - disconnect the inflation adaptor from the reservoir
 pressurization hose (1674GM)
 - connect the reservoir pressurization hose (1674GM) to the
 HP bleed-air port of the left engine (Ref. AMM TASK 29-
14-49-400-001).
 3_  If the pressure in the reservoir increases to the necessary
R  value and the air pressure drop is in the limits:
 - open and close the CB 2386GH on the panel 121VU, 
R  - do the operational test of the reservoir low air-pressure 
R  warning of the Blue hydraulic system (Ref. AMM TASK 29-34-
00-710-002).
 a If the operational test gives the correct results:_
 - no further actions are necessary. 
R  b If the operational test of the reservoir low air-pressure_ 
R  warning does not give the correct results:
 - do a check for continuity between:
 PRESS SW-B RSVR AIR (2384GH) connector A/A and PRESS SW-B
 RSVR AIR (2384GH) connector A/C (Ref. ASM 29-34/01).

R  - If there is continuity:
 - replace the PRESS SW-B RSVR AIR (2384GH) (Ref. AMM TASK
 29-34-11-000-002) (Ref. AMM TASK 29-34-11-400-002).
 c If the fault continues:_
 - do a check for continuity between:
 PRESS SW - AIR, B RSVR (2387GH) connector A/A and PRESS
 SW - AIR, B RSVR (2387GH) connector A/C (Ref. ASM 29-
34/01).

R  - If there is continuity:
 - replace the PRESS SW - AIR, B RSVR (2387GH) (Ref. AMM
 TASK 29-34-13-000-001) (Ref. AMM TASK 29-34-13-400-001).
 d If the fault continues:_
 - do a check for a ground signal at the RELAY (2388GH)
 connector 2.
 - If there is a ground signal:
 - replace the RELAY (2388GH).
 e If the fault continues:_
 - repair the wiring between the RELAY (2389GH) connector A
 and the DIODE (1164VD) connector A4 (Ref. ASM 29-34/01).

 f If the fault continues:
_

 - repair the wiring between the RELAY (2389GH) connectors 1 and 4 and the RELAY (2388GH) connectors 2 and Z (Ref. ASM 29-34/01).
 g If the fault continues:
_

 - do a check for a ground signal at the RELAY (2389GH) connector B (Ref. ASM 29-34/01).

 - If there is a ground signal: -repair the wiring between the RELAY (2389GH) connector B and the PRESS SW - AIR, B RSVR (2387GH) connector A/C (Ref. ASM 29-34/01).

 h If the fault continues:
_

 - do a check for a ground signal at the PRESS SW-B RSVR AIR (2384GH) connector A/C (Ref. ASM 29-34/01).

 - If there is a ground signal:

 - repair the wiring as necessary between the PRESS SW-B RSVR AIR (2384GH) connector A/C and the DIODE (1164VD) connector 16 and/or:

 - the PRESS SW-B RSVR AIR (2384GH) connector A/C and the RELAY 11LP connector A/45 (Ref. ASM 29-12/01)

 - the PRESS SW-B RSVR AIR (2384GH) connector A/C and the SDAC1 and the SDAC2 connectors AA3F (Ref. ASM 31-54/02).

 

 B. Do the operational test of the reservoir low air pressure warning of the Blue hydraulic system (Ref. AMM TASK 29-34-00-710-002) to make sure that the operation is correct (no maintenance message shown).
