Message Overview:
Fault Message:
L TR LOWER CH B WRG/LVT RNG
Fault Code:
7325717LBR
Associated CAS:
| Reporting LRU: | Left Engine Electronic Controller (EEC) |
| System Description: | 78-30-00 |
| Schematic Diagram: | 78-33-00 [ Global Express ] [ G5000 ] [ Global XRS ] |
| Wiring Diagram: | 78-33-01 [ Global Express ] [ G5000 ] [ Global XRS ] |
Fault Description:
The fault message is set when:
- There is an error of resistance or an open/short circuit in the primary or secondary coils of the Linear Variable Transformer (LVT) for channel B. This LVT is in the Door Position Sensor for the Lower Pivoting Door
- There is an open/short circuit in the interface wiring
Possible Causes:
- Door Position Sensor
- Left Engine Electronic Controller (EEC)
- Associated Wiring
Troubleshooting Tips:
Advisory Wire/Service Bulletin: None
Forum Articles/Infoservice/Newsletter: None
These thrust reverser circuits are continuously monitored by the FADEC.Some of the door position sensor circuits for the lower and upper pivoting door are the same and cross-connected. This can cause the fault message CAIMS - L (R) TR UPPER CH B WRG/LVT RNG to be seen at the same time. If this occurs, do the fault isolation procedure for the door position sensor of the upper pivoting door at the same time as this procedure.

Troubleshooting Recommendations:
CAUTION: DO NOT DO ELECTRICAL CHECKS INTO THE ENGINE ELECTRONIC CONTROLLER (EEC). IF YOU DO NOT OBEY THIS INSTRUCTION, DAMAGE TO THE EEC CAN OCCUR.
NOTE: It is necessary to disconnect the connector P7001 from the door position sensor of the upper pivoting door before you do electrical checks. Some of the door position sensor circuits for the lower and upper pivoting door are the same and cross-connected.
- Perform wiring checks between door position sensor and EEC.
- Connector P7002 to P1043 (CH A)
- Connector P7008 to P1046 (CH B)
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Perform a visual inspection of the interface wiring and connectors.
- If the system checks are good, do close out.
- If fault remains, continue with next step.
- Replace Door Position Sensor.
- If system checks good, do close out.
- If fault remains, continue with next step.
- Replace Left EEC.
- Do close out.
