OK: Go to next step 

1. Replace the door electrical key oscillator with a new one or normally functioning one. Refer toCOMPONENTS .
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 toREMOVAL .
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.
