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 rear door outside handle RH with a new one or normally functioning one. Refer toREMOVAL .
2. Check that the entry function operates normally.

   OK

   Operates normally

NG → See step   19 

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

1. Bring the electrical key transmitter near the rear right door outside handle, and perform a rear right 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 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.
   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 (rear door RH outside oscillator)
