ENTRY AND START SYSTEM (for Entry Function) SYSTEM DESCRIPTION

CAUTION:

If using a pacemaker, be sure to read the manual of the pacemaker before using the key, as the radio waves of the key may affect the pacemaker.


  1. ENTRY AND START SYSTEM DESCRIPTION


    1. In addition to conventional mechanical key and wireless door lock control functions, the entry and start system enables door locking/unlocking, steering lock releasing, engine control system starting and back door opening without operating the key. The only requirement is that the key is in the possession of the user.


      • This system is controlled by the certification ECU. When the certification ECU detects the presence of the key in one of the detection areas, it identifies and checks the ID code, and outputs operation signals to the related ECU in accordance with their functions.

      • The detection areas are formed by 6 oscillators (2 door oscillators, an outside oscillator and 3 indoor oscillators).

  2. DETECTION AREA

    A01IPNIE02

    1. Precautions for the entire system:


      • Be sure to carry the key during inspection of the entry and start system.

      • As weak radio waves are used to detect the key, the key detection area may decrease, or the key may not be detected correctly in the following situations.


        1. The key battery is depleted.

        2. Any facilities that generate strong radio waves, such as a TV tower, power plant, broadcast station or gas station, are located near the inspection site.

        3. A wireless device, such as a cell phone, is carried with the key.

        4. The key is in contact with or covered with metal.

        5. Electric wave type keyless entry systems are being operated nearby.

        6. The key is located near a device that generates high voltage or noise.

        7. Film with some metallic content is stuck to the back glass.

          Tech Tips

          In this case, remove the cause or unlock the door using the mechanical key.


      • Even if the key is in the vehicle exterior key detection area, the key may not operate properly due to the vehicle body design.

      • The key may not be detected correctly if it is around the vehicle windows, door handle or center of the bumper, even when it is in the detection area outside the vehicle.

      • The key may not be detected correctly if it is on the instrument panel or floor, or in the glove box, even when it is in the detection area inside the vehicle.

      • The key may not operate if the key is not held properly.

      • The entry and start system does not operate in the following conditions:


        1. The entry and start system is canceled.

        2. The key battery is completely depleted (the indicator does not blink when pushing any of the switches on the key).

  4. CONSTRUCTION AND OPERATION


    1. Key:

      A total of 7 keys can be registered.


      1. Electrical key transmitter:

        The electrical key transmitter consists of a mechanical key, a transmitter function for the wireless door lock control and a transceiver for the entry and start system.


        • The transceiver function for the entry and start system receives the signals from the oscillators and sends the ID code to the door control receiver.

        • The transmitter function for the wireless door lock control has a lock switch, unlock switch and luggage switch.

        • The mechanical key can lock/unlock all the doors. To lock or unlock the doors, remove the cap from the driver door outside handle, insert the key into the door key cylinder, and then turn it to the lock or unlock position.

        A01IQ4FE02

    2. Oscillator (each door oscillator, front floor, rear floor and inside luggage indoor oscillator, and outside oscillator):

      Each oscillator transmits the request signal received from the certification ECU, and forms a key detection area to detect the presence of a key. The detection area formed by each door oscillator and the outside oscillator is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the outside handle of each door and the center of the rear bumper.


      • The detection area of each door oscillator 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 proximity of a key. During entry lock, the detection area is formed with the lock switch on.

      • The detection area of the outside oscillator is formed when the back door opener switch is on.

      • The detection area of the indoor oscillators (front floor, rear floor and inside luggage) is formed when the driver door is opened or closed, during starting, when a warning is activated, or when the lock switch is on.

  5. ENTRY FUNCTION OPERATION


    1. The entry and start system has the following functions.

      Function Outline
      Mechanical Key Operation is the same as a conventional mechanical key.
      Wireless Door Lock Control This function remotely locks and unlocks all doors and the back door. Operation is the same as the wireless door lock control system. However, the receiver in the certification ECU uses the door control receiver to control locking and unlocking.
      Entry Illumination When a person carrying the key enters the detection area, the door will enter unlock standby mode and the room light will illuminate.
      Entry Unlock When the key is located in the detection area of the door oscillator, the door will unlock by touching the inside of the outside door handle.

  6. ENTRY UNLOCK FUNCTION


    1. The detection area is formed by communication between a door oscillator and the certification ECU when the door is locked in order to detect the person carrying the key.

    2. When the person carrying the key enters the detection area around the vehicle, the matching of the ID codes for a door oscillator and key will automatically be performed. After the matching is completed, the door will enter unlock standby mode.

    3. In unlock standby mode, the oscillator built into the outside handle starts sensing. If the outside handle is held (the back side of the handle is touched), the door unlock operation will be performed. At this time, the hazard warning lights blink twice.

    4. If any of the doors are not opened after a door unlock operation, all doors will automatically lock after 30 seconds.

  7. ENTRY LOCK FUNCTION


    1. After leaving the vehicle carrying the key, touch the lock sensor on the outside handle assembly or push the back door open switch on the back door outside handle when all doors are closed.

    2. The certification ECU determines whether the key is located inside or outside of the cabin based on the information from a door oscillator and indoor oscillator. Then matching of the ID codes is performed.

    3. When the matching result shows that the key is not detected inside the vehicle and the ID codes of the key and door oscillator match, the door lock function will operate. At this time, the hazard warning lights blink once.

    4. If the key is located inside of the cabin, the door lock function will not operate and the alarm buzzer (beep sound) will sound for 2 seconds.

  8. ENTRY BACK DOOR OPEN FUNCTION

    Stand in front of the back door with the key and push the back door opener switch to start the matching of the ID codes for the outside oscillator. If the ID codes match, the back door open operation will be performed.

  9. PREVENTION OF KEY LOCK-IN FUNCTION


    1. If the key is in the cabin, the doors are closed and the entry lock operation is attempted (the lock sensor on the door outside handle is touched), the system determines that the key is located in the cabin and unlocks the doors.

    2. If the back door is closed and the lock switch is pressed with the key in the vehicle and the other doors locked, the alarm will sound and the back door will not lock.

  10. ENTRY ILLUMINATION FUNCTION

    In order to improve ease of entering and exiting the vehicle at night, the vehicle lights illuminate when the key is brought near the vehicle.

  12. BATTERY SAVING


    1. Vehicle battery saving function:

      In the entry and start system, signals are emitted outside of the vehicle at a prescribed interval (0.25 seconds) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below exist.

      Condition Control

      Both conditions below are met for 5 days:


      • Key is not in detection area

      • Touch sensor or lock sensor operation is not performed

      		 Signal transmission interval is extended from 0.25 to 0.75 seconds

      Both conditions below are met for 14 days:


      • Key is not in detection area

      • Touch sensor or lock sensor operation is not performed

      		 Automatically deactivates the entry and start system

      Reinstatement Conditions:


      • A wireless door lock control signal (lock, unlock) is input and the ID matches.

      • A user carries the key and touches the lock sensor on a door outside handle assembly.

      • The driver door is locked or unlocked by the mechanical key.

    2. Key battery and vehicle battery saving function:

      In the entry and start system, if the key is constantly located within the vehicle exterior detection area of the doors, the system maintains periodic communication with the key. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could be drained. For this reason, if this state continues for more than 10 minutes, the entry and start system automatically becomes deactivated.

      Reinstatement Conditions:


      • A wireless door lock control signal (lock, unlock) is input and the ID code matches.

      • A user carries the key and touches the lock sensor on a door outside handle assembly.

      • The driver door is locked or unlocked by the mechanical key.
