   NOTE:

   If the key is brought within 0.2 m (0.6 ft) of the rear bumper, communication is not possible.

   HINT: 

   • When the electrical key transmitter is brought near the electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the inspection result is that 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.

   Result	Proceed to
   Operation check fails	A
   Operation check is normal	B

B → AFFECTED BY WAVE INTERFERENCE 

A: Go to next step 

1. Diagnostic mode inspection (rear inside oscillator)

   1. Connect the Techstream to the DLC3.
   2. Turn the engine switch on (IG).
   3. Turn the Techstream on.
   4. Enter the following menus: Body Electrical / Smart Access / Smart Communication Check /Overhead + Luggage.
   5. When the electrical key transmitter is held at the same height as the rear bumper upper surface and aligned with the center of the rear of the vehicle, check that the wireless door lock buzzer sounds.

      HINT: 

      If the buzzer sounds, it can be determined that the luggage compartment exterior transmitter is operating normally.

      OK

      Wireless door lock buzzer sounds
