    Result: 

    DTC is not output 

    See step  2

  2. CHECK WAVE ENVIRONMENT 
    1. Move the electrical key transmitter sub-assembly as described below and perform the operation inspection.

      HINT: 

      • When the electrical key transmitter sub-assembly is brought near the front door outside handle assembly (for driver door) 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 wave of the wireless function and entry function are the same, but the wave logic is different. As a result, it is possible that only the wireless function or only the entry function is affected by wave interference.
      1. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for driver door) and perform a driver door entry lock and unlock operation check.
        NOTE:

        If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the door handle, communication may not be possible.

        *a Approximately 0.3 m (0.984 ft.)
      2. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for front passenger door) and perform a front passenger door entry lock and unlock operation check.
        NOTE:

        If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the door handle, communication may not be possible.

        GTY376711Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        *a Approximately 0.3 m (0.984 ft.)
      3. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the electrical key antenna (outside luggage) and perform a back door open function check.
        NOTE:

        If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the rear bumper, communication may not be possible.

        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.

        *a Approximately 0.3 m (0.984 ft.)
      Result Proceed to
      All operation checks fail
      All operation checks are normal
      Some operation checks are normal

    Result: 

    All operation checks are normal 

    AFFECTED BY WAVE INTERFERENCE 

    Result: 

    Some operation checks are normal 

    GO TO OTHER PROBLEM (PROCEED TO PROBLEM SYMPTOMS TABLE FOR EACH DOOR). Refer to  PROBLEM SYMPTOMS TABLE [12/2012 - 08/2016]  . 

    Result: 

    All operation checks fail 

    See step  3

  3. CHECK KEY DIAGNOSTIC MODE 
    1. Check the following antennas in key diagnostic mode.
    2. Select either channel 1 or channel 2 and perform the key diagnostic mode inspection for each channel.

      HINT: 

      If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

      1. Check the electrical key antenna (for driver door):

        When the electrical key transmitter sub-assembly is brought within 0.7 to 1 m (2.30 to 3.28 ft.) of the front door outside handle assembly (for driver door), check that the wireless door lock buzzer sounds.
