All Door Entry Lock/Unlock Functions do not Operate, but Wireless Functions Operate [08/2015 - 08/2019]: Procedure

  1. READ VALUE USING TECHSTREAM (KEY CANCEL SWITCH) 
    1. Using the Techstream, read the Data List (Refer to DATA LIST / ACTIVE TEST [08/2015 - 08/2019] ).
      SMART ACCESS

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Auto Entry Cancel SW Entry cancel function setting / OFF or ON Mode status displayed
      ON: Smart access system with push-button start canceled
      OFF: Smart access system with push-button start not canceled      		 The default setting for the entry cancel function is OFF. If the customer requests that the smart access system with push-button start functions (locking and unlocking the doors while carrying the key, etc.) be canceled, the setting can be changed through the customize function (Refer to CUSTOMIZE PARAMETERS [08/2015 - 08/2019] ).
      RESULT

      Result Proceed to
      Entry door lock function cancel is OFF A

    Result: 

    B 

    PERFORM CANCELLATION OF ENTRY KEY CANCEL FUNCTION 

    (Refer to CUSTOMIZE PARAMETERS [08/2015 - 08/2019] )

    Result: 

    A 

    See step  2

  2. CHECK WAVE ENVIRONMENT 
    1. Move the electrical key transmitter as described below and perform the operation inspection (Refer to OPERATION CHECK [08/2015 - 08/2016] , or refer to OPERATION CHECK [08/2016 - 08/2019] ).

      HINT: 

      • When the electrical key transmitter is brought near the front door outside handle assembly LH 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 approximately 0.3 m (0.98 ft.) from the front door outside handle assembly LH and perform a driver door entry lock and unlock operation check.

        *a Approximately 0.3 m (0.98 ft.)
        NOTE:

        If the key is brought within 0.2 m (0.66 ft.) of the door handle, communication may not possible.

      2. Bring the electrical key transmitter approximately 0.3 m (0.98 ft.) from the front door outside handle assembly RH and perform a front passenger door entry lock and unlock operation check.

        *a Approximately 0.3 m (0.98 ft.)
        NOTE:

        If the key is brought within 0.2 m (0.66 ft.) of the door handle, communication may not possible.

      3. Bring the electrical key transmitter approximately 0.3 m (0.98 ft.) from the electrical key antenna (outside luggage) and perform an entry back door unlock function check.

        TEXT IN ILLUSTRATION

        *a Approximately 0.3 m (0.98 ft.)
        NOTE:

        If the key is brought within 0.2 m (0.66 ft.) of the rear bumper, communication may not 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 electric 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.
          1. 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 key detection area) and RF band (used by the key 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
