OK: END (DOOR ELECTRICAL KEY OSCILLATOR IS DEFECTIVE) 

1. Replace the front door outside handle LH with a new one or normally functioning one (see REMOVAL  ).
2. Check that the entry function operates normally.

   OK: Operates normally 

NG: REPLACE FRONT DOOR ECU LH  (See INSTALLATION )

OK: END (FRONT DOOR OUTSIDE HANDLE LH IS DEFECTIVE) 

1. Bring the electrical key transmitter near the driver door outside handle, and perform a driver 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 driver 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	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 (driver 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 + Driver 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 driver seat outside transmitter is operating normally.

      OK: Wireless door lock buzzer sounds 

NG: Go to step 11
