OK: Go to next step 

1. Replace the door electrical key oscillator with a new one or normally functioning one. Refer to COMPONENTS [09/2012 - ] .
2. Check that the entry function operates normally.

   OK

   Operates normally

NG → See step   9 

OK → END (DOOR ELECTRICAL KEY OSCILLATOR IS DEFECTIVE) 

1. Replace the front door outside handle RH with a new one or normally functioning one. Refer to REMOVAL [09/2012 - ] .
2. Check that the entry function operates normally.

   OK

   Operates normally

NG → See step   19 

OK → END (FRONT DOOR OUTSIDE HANDLE RH IS DEFECTIVE) 

1. Bring the electrical key transmitter near the front passenger door outside handle, and perform a front passenger door entry lock and unlock operation check.

   NOTE:

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

   HINT: 

   • When the electrical key transmitter is brought near the front 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.
   RESULT
   
   

   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 (front passenger door outside 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 + Passenger Side.
   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 front passenger seat outside transmitter is operating normally.

      OK

      Wireless door lock buzzer sounds
