Troubleshooting Recommendations:

  1. Perform wiring checks of the Baggage Door Handle Proximity Sensor wires between the LGECU connector A52AP1 and splice SP702. (A52AP1-C5 to P313-44 to SP986 to SP702 and A52AP1-D5 to P313-45 to SP986 to SP702).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Perform and inspection and wiring checks of SP986 and SP702 contacts/pins.

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  3. Perform a visual inspection of the wires/harness between Baggage Door Handle Proximity Sensor and splices SP986 and SP702. Repair as required.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  4. Re-seat LGECU.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  5. Replace Baggage Door Handle Proximity Sensor.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  6. Replace LGECU.
