NG → See step   8 

OK: Go to next step 

1. Bring the electrical key transmitter approximately 0.3 m (0.984 ft.) from the door outside handle (for front passenger side) and perform a front passenger side door entry lock and unlock operation check. Refer to OPERATION CHECK [08/2014 - ] .
   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 front passenger side door outside handle, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If 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 function operates normally.
