  2. SYSTEM CONTROL


    1. Operation


      1. The special functions of the entry and start system only work when the electrical key transmitter sub-assembly is in the actuation area formed by the antennas.

      2. The indoor electrical key antenna (front), indoor electrical key antenna (center), and indoor electrical key antenna (rear) form the interior actuation area.

      3. The door electrical key antenna LH, door electrical key antenna RH, and outside electrical key antenna form the exterior actuation area.

        *c Exterior Actuation Area - -
        Actuation Area Detail
        Interior The interior actuation area of the indoor electrical key antennas (front, center, rear) is formed when the driver door is opened or closed, when the engine switch is pushed, when a warning is activated, or when a lock sensor is on.
        Exterior The exterior actuation area formed by the door electrical key antennas (LH, RH) and outside electrical key antenna is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of the front doors, or the right side of the rear bumper.
        Around Front Doors The exterior actuation area of the door electrical key antennas (LH, RH) is formed by transmitting a request signal every 0.25 seconds while the engine switch is off and each door is locked. In this way it detects the presence of an electrical key transmitter sub-assembly. When locking the door using the lock sensor on the outer door handle, the actuation area is formed when the lock sensor is touched.
        Around Back Door The exterior actuation area of the outside electrical key antenna is formed when the back door open switch is on.

        Note


        • Normally, the operation of the engine switch is disabled while the vehicle is being driven. However, in an emergency, by pushing the engine switch for approximately 2 seconds or more or pushing the engine switch 3 times or more in a row, the driver can stop the engine while the vehicle is in motion.

        • If no signals are transmitted to the certification ECU (smart key ECU assembly) due to malfunctions in the stop light switch or park/neutral position switch assembly, the engine may not start when the engine switch is pushed with the brake pedal*1 or clutch pedal*2 depressed. In such cases, performing the following procedure may enable the engine to start: 1) push the engine switch to turn the power source from off to on (ACC), and 2) push the engine switch again and hold it for 15 seconds or more.

        • The above 2 operations must be applied only in emergency situations. Under normal conditions, the engine must not be stopped by pushing the engine switch while driving. Also, it should not be started without depressing the brake pedal*1 or clutch pedal*2 or when the shift lever is in any position other than P or N.

    6. Battery Saving


      1. Battery saving preserves the vehicle and key batteries. It is activated when the vehicle remains parked for a long time and when the electrical key transmitter sub-assembly is left in the exterior actuation area.

        Condition Control Reinstatement Condition
        When the vehicle remains parked for a longtime.

        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 condition 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

        - Outside 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 auxiliary 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.

    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 entry and start function 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. Key Cancel


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


        • Entry Lock

        • Entry Unlock

        • 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 operation procedure is as follows:

        - Press the unlock button 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 button 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 button 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.

    9. Key Code Registration Function


      1. The table below shows the 4 special ID code registration function modes through which up to 7 different transmitter recognition codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM. 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 a transmitter or 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. If the number of codes exceeds 7, the oldest registered code is cleared first.
        Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.
        Prohibit To clear all the registered codes and to prohibit the wireless door lock function. This mode is used when an electrical key transmitter sub-assembly is lost.

    10. 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 back 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 (LH and RH), the interior light and engine switch illumination illuminate.
        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 either front outside door handle is touched.


        • The driver outside door handle unlocks the driver door.

        • The front 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 (Default Setting)

        • All Door Mode
        Entry Lock When an electrical key transmitter sub-assembly is located in the exterior actuation area of an electrical key antenna (driver or front passenger door) and the engine switch is off, all doors can be locked by simply touching the lock sensor.
        Back Door Open When an electrical key transmitter sub-assembly is in the exterior actuation area of the outside electrical key antenna (back door), the back door opens manually by simply pushing the back door opener switch assembly.
        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*1 in order to alert the driver.


        • An exit warning is activated if the shift lever is in any position other than P*2 or N*3.

        • An exit warning is activated if the shift lever is in P*2 or N*3 and the engine 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 engine switch is operated while the electrical key transmitter sub-assembly is outside the actuation area.

        • A warning is activated if the lock button 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 (driver, front passenger, or back 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 be drained.
        Key Cancel

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


        • Entry unlock/lock

        • Back door open

        • Prevention of key confinement

        • Warning
        Key Code Registration A total of 7 electrical key transmitter sub-assemblies can be registered. Key registration enables the registering (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the certification ECU (smart key ECU assembly).

        *1: Models with dot LCD type multi-information display

        *2: Models with multidrive/continuously variable transaxle

        *3: Models with multi-mode manual transaxle

      2. The wireless door lock control system allows the following functions:

        Function Outline
        All Doors Lock Pressing the lock button of the electrical key transmitter sub-assembly locks all doors.
        All Doors Unlock (1-step Unlock) Pressing the unlock button of the electrical key transmitter sub-assembly once unlocks all doors.
        Back Door Open Keeping the back door unlock button of the electrical key transmitter sub-assembly pushed longer than about 0.8 seconds opens the back door.
        Answer Back When the doors are being locked or unlocked using the electrical key transmitter sub-assembly, the hazard warning lights blink once while locking and twice while unlocking. Also, the answer back function operates when the doors are locked by the automatic relock function.
        Automatic Relock If none of the doors are opened within 30 seconds after they are unlocked using the wireless door lock remote control, all the doors will be locked again automatically.
        Repeat If a door is not locked in response to the locking operation of the electrical key transmitter sub-assembly, the main body ECU (multiplex network body ECU) will output a lock signal again after 1 second elapses.
        Security Sends a door lock/unlock operation request signal as a rolling code.
        Door Ajar Warning If any door is open or ajar, pushing the lock button of the electrical key transmitter sub-assembly will cause the wireless door lock buzzer to sound for about 5 seconds as a warning.

  4. 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 engine 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.
