   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the door handle, communication is not possible.

   HINT: 

   • When the electrical key transmitter is brought near the rear right passenger door outside handle, 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.

   OK

   Entry functions operate normally.

NG → See step   5 

OK → AFFECTED BY WAVE INTERFERENCE 

1. Diagnostic mode inspection door electrical key oscillator

   1. Connect the Techstream to the DLC3.
   2. Turn the power switch ON (IG).
   3. Turn the Techstream on.
   4. Enter the following menus: Body Electrical/ Smart Access / Smart Communication Check /Overhead + Driver Side Rear.
   5. When the electrical key transmitter is in the position shown in the illustration, check that the wireless door lock buzzer sounds.

      HINT: 

      If the buzzer sounds, it can be determined that the rear right seat outside transmitter is operating normally.

      OK

      Wireless door lock buzzer sounds
