Troubleshooting Recommendations:

  1. Perform wiring check of the RIGHT EMERGENCY DOOR PROXIMITY SENSOR wires between the LGECU connector A52AP1 and splice SP699 Check wiring between A52AP1 Pin C10 to SP699 and also wiring between A52AP1 Pin D10 to SP699.

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

  2. Perform and inspection of splice SP699 contacts / pins as per wiring check.

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

  3. Perform a visual inspection of the wires / harness between RIGHT EMERGENCY DOOR PROXIMITY SENSOR and splice SP699.

    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 RIGHT EMERGENCY DOOR PROXIMITY SENSOR.

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

  6. Replace LGECU.
  7. Do close out.
