  2. CHECK WAVE ENVIRONMENT 
    1. Install the transmitter battery to the electrical key transmitter sub-assembly.

      Refer to REMOVAL [11/2018 - ]

    2. Bring the electrical key transmitter sub-assembly near the No. 1 indoor electrical key antenna assembly (front floor) and perform an smart key system check.
      NOTE:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (front floor).

      Refer to PARTS LOCATION [11/2018 - 02/2019] , or refer to PARTS LOCATION [02/2019 - 12/2021]

      HINT: 

      • As the effect of wave interference decreases by moving the electrical key transmitter sub-assembly close to each indoor electrical key antenna assembly, it may be possible to check whether wave interference is the cause of the problem.
      • 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.

      OK

      The hybrid control system starts when the electrical key transmitter sub-assembly is held near each indoor electrical key antenna assembly and the power switch is pressed with the brake pedal depressed.

  3. CHECK KEY DIAGNOSTIC MODE 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Smart Key / Utility / Communication Check(Key Diag Mode).
    5. Check the No. 1 indoor electrical key antenna assembly (front floor).

      When the electrical key transmitter sub-assembly is at either inspection point, check that the buzzer sounds.

      HINT: 

      • Select either channel 1 or channel 2 and perform the key diagnostic mode inspection 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.
      • It is possible to check which No. 1 indoor electrical key antenna assembly (front floor) is operating by the sounding of the buzzer.
      • When the buzzer does not sound for No. 1 indoor electrical key antenna assembly (front floor), it can be judged that the certification ECU (smart key ECU assembly), which controls the No. 1 indoor electrical key antenna assembly (front floor), is malfunctioning.
