Message Description:
Passenger Door Handle Proximity Sensor has been detected failed by the Landing-Gear Electronic Control-Unit (LG ECU).
Possible Causes:
- Passenger Door Handle Proximity Sensor
- Landing-Gear Electronic Control-Unit (LG ECU) (A52)
- Associated Wiring
Troubleshooting Tips:
Advisory Wire/Service Bulletin: None
Full Throttle Blog/Forum Articles/Infoservice/Newsletter: None
Flight Operation Notifications Manual (FONM): None
NOTES:
- The logic of the Main Entry Door (Passenger door) FWD G-LOCK HOOK & AFT G-LOCK HOOK sensors on the Channel B of the LGECU is as follow:
- When door is open:
- Both sensors are showing LOCKED and Handle sensor is showing NOT STOWED
- When door is closed:
- Both sensors are showing NOT LOCKED and Handle sensor is showing STOWED
- Look to Proximity sensor’s as the fault.
- Look at wiring connections for splice SP709.
- When door is open:

Troubleshooting Recommendations:
- Perform wiring checks of the Passenger Door Handle Proximity Sensor wires between the LGECU connector A52AP1 and splice SP709.
From To Expected Result Result A52AP1 - C8 SP709 - A1 Continuity A52AP1 - D8 SP709 - B1 Continuity - 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 and inspection and wiring check of splice SP709 contacts/pins.
- 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 wires/harness between the Passenger Door Handle Proximity Sensor and splice SP709. Repair as required.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Re-seat LGECU.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Replace Passenger Door Handle Proximity Sensor.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Replace LGECU.
- Do close out.
