Message Overview:

Message Name:

RIGHT BLEED PRESSURE TRANSDUCER OUTPUT IS OUT OF RANGE

Message Code: 361OBS012
Effectivity: All
System: Bleed Air System
System Description: 36-11-00
Schematic Diagram: 36-11-00 [ Global Express ]  [ G5000 ]  [ Global XRS ]
Wiring Diagram: 36-11-04 [ Global Express ]  [ G5000 ]  [ Global XRS ]

Message Description:

The Bleed Management Controller (BMC) senses that the Bleed Pressure Transducer (BPT) output is not between 0.02 and 9.9 VDC.

Possible Causes:

  • Right Bleed Pressure Transducer (BPT) (MT112)
  • Junction Box 3 (JB3)
  • Junction Box 4 (JB4)
  • Right Bleed Management Controller (BMC) (A70)
  • Associated Wiring

Troubleshooting Tips:

Advisory Wire/Service Bulletin: None

Forum Articles/Infoservice/Newsletter: None

Troubleshooting using CAIMS message if the active channel of the bleed management controller sends the message RIGHT BLEED PRESS XDCR /WRG to CAIMS when R BPT output is out of range.

Troubleshooting Recommendations:

  1. Swap Right BPT with Left BPT.

    1. If the system checks are good, replace right BPT and do close out.
    2. If fault remains, continue with next step.

  2. Remove power from the aircraft. Disconnect left BPT connector (MT96P1) and aft pressure bulkhead connector (P625). Remove JB3 to get access to the connector. Perform a continuity check between the BPT and the JB4 as follows:

    From To Result
    MT112P1-A P600-x
    MT112P1-B GS296
    JB4AP1-11D J600-x

    1. If there is no continuity, repair defective wiring as required and do close out.
    2. If there is continuity, continue with next step.

  3. Perform a continuity check for an open circuit between the contacts on JB4 that follows:

    From To Result
    JB4AJ1-11A JB4AJ1-11D

    1. If there is no continuity, replace JB3 (PCB2) and do close out.
    2. If there is continuity, continue with next step.

  4. Disconnect the connectors P610, MT112P1 of right BPT and A70P1 of right BMC. Perform a continuity check for an open circuit between the contacts on right BPT that follows:

    From To Result
    MT112P1-C P610-p
    MT112P1-D P610-q
    A70P1-7 J610-p
    A70P1-8 J610-q

    1. If there is no continuity, repair defective wiring as required and do close out.
    2. If there is continuity, continue with next step.

  5. Perform a continuity check as follows:

    From To Result
    MT112P1-C MT112P1-D
    MT112P1-C MT112P1-Sh
    MT112P1-D MT112P1-Sh
    A70P1-7 A70P1-8
    A70P1-7 A70P1-Sh
    A70P1-8 A70P1-Sh

    1. If there is continuity, repair defective wiring as required and do close out.
    2. If there is no continuity, continue with next step.

  6. Replace Right BMC.
  7. Do close out.
