    See step  3

  3. CHECK WAVE ENVIRONMENT 
    1. Move the electrical key transmitter sub-assembly as described below and perform the operation inspection (Refer to OPERATION CHECK [03/2017 - 12/2017] Refer to OPERATION CHECK [12/2017 - ] ).

      HINT: 

      • When the electrical key transmitter sub-assembly is brought near the front door outside handle assembly or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • The transmitting waves of the wireless functions and entry functions are the same, but the wave logic is different. Therefore, it is possible that only the wireless functions or only the entry functions are affected by wave interference.
    2. Bring the electrical key transmitter sub-assembly near the front door outside handle assembly LH, and perform a front driver door entry lock and unlock operation check.

      NOTE:

      If the key is brought within 0.2 m (0.656 ft.) of the front door outside handle assembly LH, communication is not possible.

      TEXT IN ILLUSTRATION

      *1 Electrical Key Transmitter Sub-assembly
      *a Approximately 0.3 m (0.98 ft.)

      HINT: 

      • If the inspection result is that the problem only occurs in certain locations or at certain times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
      • If wave interference seems to be the likely cause of the problem, ask the customer if the problem occurs in specific locations.
      • Move the vehicle to a different location, perform the following procedure and check if the symptoms can be reproduced.
      • If a tool for checking electric waves, such as a signal strength meter, is available, move around the area while observing both the LF band (used by the vehicle antenna to form the detection area) and RF band (used by the electrical key transmitter sub-assembly for transmission) to check for locations where there is wave interference.
      RESULT

      Result Proceed to
      All operation checks fail A
      All checks are normal B
      Some operation checks are normal C
