      TEXT IN ILLUSTRATION

      *1 Electrical Key Transmitter Sub-assembly
      *a Approximately 0.3 m (0.984 ft.)
      NOTE:

      If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the rear bumper, communication is not possible.

      HINT: 

      • When pressing the luggage compartment door opener outer switch, hold the electrical key transmitter sub-assembly approximately 1 m (3.28 ft.) above the ground and approximately 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.
      • When the electrical key transmitter sub-assembly is brought near the electrical key antenna (outside luggage), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • If the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

      OK

      Entry functions operate normally.

    Result: 

    OK 

    AFFECTED BY WAVE INTERFERENCE 

    Result: 

    NG 

    See step  5

  5. CHECK KEY DIAGNOSTIC MODE 
    1. Check the following antennas in the key diagnostic mode (Refer to OPERATION CHECK [03/2017 - 12/2017] Refer to OPERATION CHECK [12/2017 - ] ).

      TEXT IN ILLUSTRATION

      *1 Electrical Key Transmitter Sub-assembly
      *a 0.7 to 1.0 m (2.30 to 3.28 ft.)
    2. When the electrical key transmitter sub-assembly is held at the same height as the rear bumper upper surface, align it with the center of the rear of the vehicle and check that the wireless door lock buzzer sounds.

      HINT: 

      • Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and align it with the center of the rear of the vehicle (0.7 to 1.0 m (2.30 to 3.28 ft.)). Make sure that the direction of the electrical key transmitter sub-assembly is as shown in the illustration.
      • If the buzzer sounds, it can be determined that the luggage compartment exterior transmitter is operating normally.

      OK

      Wireless door lock buzzer sounds.
