        Condition Control Reinstatement Condition
        When 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 power 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 power 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.
        When 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 doors are locked or unlocked by touching the lock/unlock sensor on the front or rear 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 auxiliary battery by turning the power source mode to off when approximately 60 minutes have elapsed since (a) the P position switch (transmission shift main switch) was pushed and the power source was turned to on (ACC), or (b) the fuel cell system is off with the shift position P selected, the power source on (IG) and the vehicle stationary.

    7. 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 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 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.

    8. Entry unlock mode switching function (manual operation)


      1. The following entry unlock modes can be selected when using the entry unlock mode switching function.


        • All door unlock mode: When the sensor of a front door outside handle assembly is touched, an entry unlock operation is performed simultaneously for all doors.

        • Driver door unlock mode: When the sensor of the driver side door outside handle assembly is touched, an entry unlock operation is performed for the driver door only. If any other door handle is touched, an entry unlock operation is performed simultaneously for all doors.

      2. When customizing through manual operation:


        1. Turn the power switch off.

        2. Check that the LED of the electrical key transmitter sub-assembly is not illuminated, and then press and hold the lock and unlock switches of the electrical key transmitter sub-assembly for 5 seconds or more while the electrical key transmitter sub-assembly is in the actuation area.

        3. Check the current setting.

        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.

    10. 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. FUNCTION


    1. Entry Function


      1. The entry function consists of the following functions:

        Function Outline
        Wireless Door Lock Control This function is a convenient system for locking and unlocking all the doors and luggage compartment door at a distance. The operation of this function is the same as that in the wireless door lock control system.
        Entry Illumination When an electrical key transmitter sub-assembly enters the exterior actuation area of the door electrical key antennas, the interior light illuminates.
        Entry Unlock

        When an electrical key transmitter sub-assembly is located in the exterior actuation area of any door electrical key antenna, the door will unlock after the inner part of an outside door handle is touched.


        • The driver outside door handle unlocks the driver door.

        • The passenger outside door handle unlocks all doors.
        Entry Unlock Mode Switching

        Allows switching between 2 modes that can be operated with the entry unlock function.


        • Driver Door Mode

        • All Door Mode (Default Setting)
        Entry Lock When an electrical key transmitter sub-assembly is located in the exterior actuation area of an electrical key antenna and the power switch is off, all doors can be locked by simply touching the lock sensor.
        Luggage Compartment Door Open When an electrical key transmitter sub-assembly is in the exterior actuation area of the outside electrical key antenna (luggage compartment door), the luggage compartment door opens manually by simply pushing the luggage compartment door open switch.
        Prevention of Key Confinement The key confinement prevention function prevents the vehicle from being locked with an electrical key transmitter sub-assembly left inside it. This function operates in 2 different situations: when the lock knob is used (keyless lock) and when an outside door handle lock sensor is used (lock sensor).
        Warning

        When any of the situations below occur, the entry and start system causes the certification ECU (smart key ECU assembly) to sound the buzzer in the combination meter and the wireless door lock buzzer, and indicates a warning on the multi-information display in order to alert the driver.


        • An exit warning is activated if the shift position is in any position other than P.

        • An exit warning is activated if the shift position is in P and the power switch is in a mode other than off.

        • A warning is activated if the occupant leaves with the electrical key transmitter sub-assembly in inappropriate circumstances.

        • A warning is activated if the power switch is operated while the electrical key transmitter sub-assembly is outside the actuation area.

        • A warning is activated if the lock switch is operated while the electrical key transmitter sub-assembly is inside the vehicle.

        • A warning is activated if the key battery is weak.
        Battery Saving If the electrical key transmitter sub-assembly remains within the exterior actuation area of any electrical key antenna (front door, rear door, or luggage compartment door), the system maintains periodic communication with the electrical key transmitter sub-assembly. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could become drained.
        Key Cancel

        The following key functions can be canceled by following the specified procedure.


        • Entry unlock/lock

        • Luggage compartment door open

        • Prevention of key confinement

        • Warning
        Key Code Registration A total of 7 electrical key transmitter sub-assemblies can be registered.

  5. DIAGNOSIS


    1. Start Function


      1. The certification ECU (smart key ECU assembly) can detect malfunctions in the 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 warning continues for 15 seconds even after the power switch is turned off.

      4. The 5-digit DTCs can be read after connecting the Global TechStream (GTS) to the DLC3.

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