    See step  9

    Result: 

    OK 

    See step  4

  4. CHECK WAVE ENVIRONMENT 
    1. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the electrical key antenna (outside luggage compartment) and perform an entry luggage compartment open function check.
      GTY603286Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      *a Approximately 0.3 m (0.984 ft.)

      HINT: 

      • Communication may not be possible if the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the rear bumper.
      • When the electrical key transmitter sub-assembly is brought near the electrical key antenna (outside luggage compartment), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • 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.
      • There may be wave interference if the vehicle is near broadcasting antennas, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc. In this case, move the vehicle to a different location and check if there is any improvement.
      • If a tool for checking radio 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.

      OK

      Entry functions operate normally.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    AFFECTED BY WAVE INTERFERENCE 

    Result: 

    NG 

    See step  5

  5. CHECK KEY DIAGNOSTIC MODE 
    1. Check the following antenna in key diagnostic mode.

      Body Electrical > Smart Key > Utility 

      Tester Display
      Communication Check (Key Diag Mode)
    2. When the electrical key transmitter sub-assembly is brought within 0.7 to 1 m (2.30 to 3.28 ft.) of the electrical key antenna (outside luggage compartment), check that the wireless buzzer sounds.

      HINT: 

      • Select either channel 1 or channel 2 and inspect key diagnostic mode for each channel.
      • 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.
