Troubleshooting Recommendations:

  1. Perform wiring checks of the Pass Door Forward G-Lock Hook Proximity Sensor wires between the LGECU connector A52AP1 and splice SP697 (MT42 Passenger Door FWD Claw) 

    From To Expected Result Result
    A52AP1 - C14 SP697 - A1 Continuity
    A52AP1 - D14 SP697 - B1 Continuity

    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 a inspection and wiring checks of splice SP697 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 Pass Door Forward G-Lock Hook Proximity Sensor and splice SP697. 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 Pass Door Forward G-Lock Hook 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.
