        Condition Control Reinstatement Condition
        The vehicle remains parked for a long time.

        Control 1:

        No response from electrical key transmitter sub-assembly for more than 5 days


        • Door electrical key antennas and electrical key antenna stop emitting signals for creating the actuation area.

        		 When the engine switch is turned on (IG), the control is canceled and the system is returned to normal.

        Control 2:

        No response from electrical key transmitter sub-assembly for more than 14 days


        • Door electrical key antennas and electrical key antenna stop emitting signals for creating the actuation area.

        • Front passenger door lock sensor and unlock sensor are disabled.

        When the engine switch is turned on (IG), the control is canceled and the system is returned to normal.

        When one of the following conditions is met, the control is returned to control 1:


        • The doors are locked or unlocked using wireless remote control.

        • The doors are locked or unlocked by touching the lock/unlock sensor on the driver door.

        • A door is locked or unlocked using the mechanical key.

        • Door is opened → closed.
        The electrical key transmitter sub-assembly is left in the exterior detection area.

        This state continues longer than 10 minutes


        • Electrical key antenna that is detecting the electrical key transmitter sub-assembly stops emitting signals for creating the actuation area.

        The control is stopped when one of the following conditions is met:


        • The doors are locked or unlocked using wireless remote control.

        • The doors are locked or unlocked by touching the lock/unlock sensor on the front door.

        • A door is locked or unlocked using the mechanical key.

      2. In addition to the above functions, the auto power off function helps to reduce drain on the vehicle battery by turning the power source mode to off when approximately 60 minutes have elapsed since (a) the shift lever was moved to P with the power source on (ACC), or (b) the engine was turned off with the shift lever in P, the power source on (IG) and the vehicle stationary.

    11. Battery Saving Function of Electrical Key Transmitter Sub-assembly


      1. This function cancels the signal reception waiting state of the electrical key transmitter sub-assembly, reducing the consumption of current from its battery.

      2. The electrical key transmitter sub-assembly can be placed into and taken out of battery saving mode. When the electrical key transmitter sub-assembly is in battery saving mode, the smart entry and start system will not be able to detect the transmitter, as the transmitter will not respond to signals from the vehicle. The function of the smart entry and start system will not operate if the electrical key transmitter sub-assembly is in battery saving mode.

      3. Pressing the unlock switch of the electrical key transmitter sub-assembly twice while pressing the lock switch (the indicator light of the electrical key transmitter sub-assembly blinks 4 times) selects battery saving mode for the electrical key transmitter sub-assembly.

      4. Battery saving mode can be canceled by pressing any switch on the electrical key transmitter sub-assembly.

    12. Key Cancel


      1. The following system functions can be deactivated by using the key cancel procedure.


        • Entry Lock

        • Entry Unlock

        • Entry Illumination

        • Back Door Open

        • One-motion Power Slide

        • Prevention of Key Confinement

        • Warning

      2. The system functions can be deactivated by using the following key cancel procedure when the engine switch is off and the driver door is closed and unlocked.

        Key Cancel Procedure

        The procedure is as follows:


        • Press the unlock switch of the electrical key transmitter sub-assembly once.

        • Within 5 seconds of the step above, open the driver door (Driver Door: Close → Open).

        • Within 5 seconds of the step above, press the unlock switch of the electrical key transmitter sub-assembly twice.

        • Repeat close → open for the driver door twice* (Driver Door: Open → Close → Open → Close → Open).

        • Press the unlock switch of the electrical key transmitter sub-assembly twice*.

        • Repeat close → open for the driver door once* (Driver Door: Open → Close → Open).

        • Within 5 seconds of the step above, close the driver door.

        When the cancel procedure is complete, the buzzer sounds twice. Meanwhile, when the procedure is performed again to resume the system, the buzzer sounds once.

        *: Perform all these 3 steps within 30 seconds of the previous step.

    13. Key Code Registration Function


      1. The table below shows the 3 special ID code registration function modes through which up to 7 different transmitter recognition codes can be registered. For details, refer to the Repair Manual.

        Mode Function
        Rewrite Clears all previously registered codes and registers only the newly received codes. This mode is used whenever the certification ECU (smart key ECU assembly) is replaced.
        Add Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter.
        Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.

  4. DIAGNOSIS


    1. Start Function


      1. The certification ECU (smart key ECU assembly) can detect malfunctions in the smart entry and start system when the power source is on (IG).

      2. When the ECU detects a malfunction, a message is displayed on the multi-information display to warn the driver. At the same time, the ECU stores a 5-digit Diagnostic Trouble Code (DTC) in its memory.

      3. The indicator light remains illuminated for 15 seconds even after the engine switch is turned off.

      4. The 5-digit DTCs can be read after connecting the Techstream to the DLC3.

      5. The smart entry and start system may not operate successfully if a malfunction occurs.
