  NOTE:
  If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.
  
  HINT:
  - When pressing the lock switch and touching the touch sensor, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.
  - When the key is brought near the front door outside handle assembly (for front passenger side), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
  - If the operation 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 functions operate normally.
NG → See step 3

OK → AFFECTED BY WAVE INTERFERENCE

CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU - FRONT DOOR OUTSIDE HANDLE)
