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 starting and luggage compartment door opening without operating the electrical key. The only requirement is that the electrical key is in the user's possession.
   • This system is controlled by the certification ECU. When the certification ECU detects the presence of the smart access system with push-button start 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, 2 luggage compartment oscillators, and 2 cabin oscillators).

1. Precautions for the entire system:
   • Be sure to carry the electrical key during inspection of the smart access system with push-button start.
   • As weak radio waves are used to detect the electrical key, the electrical key detection area may decrease, or the electrical key may not be detected correctly in the following situations: (a)The electrical 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 cellular phone, is carried with the electrical key.
4. The electrical key is in contact with or covered with metal.
5. Another wireless door lock control function is operated near the vehicle.
6. The electrical key is located near a device that generates high voltage or noise.

• The electrical key may be difficult to operate for a reason relating to the vehicle body shape.
• The electrical key may not be detected correctly if it is around the vehicle's windows, the door handle or center of the bumper even when it is in the detection area outside the vehicle.
• The electrical key may not be detected correctly if it is on the instrument panel, rear package tray or floor, or in the glove box even when it is in the detection area inside the vehicle.
• The engine cannot be started even when the electrical key is in the detection area inside the luggage compartment.
• The electrical key may not operate if the electrical key is not held properly.
• The smart access system with push-button start does not operate in the following conditions:
  1. The smart access system with push-button start is canceled.
  2. The electrical key battery is completely depleted (the indicator does not blink when pushing any of the buttons on the electrical key).

1. Electrical Key

   The electrical key consists of a mechanical key, a transmitter function for the wireless door lock control and a transceiver for the smart access system with push-button start.

   • The transceiver function for the smart access system with push-button start receives the signals from the oscillators and sends the ID code to the tuner.
   • The transmitter function for the wireless door lock control has a LOCK switch, UNLOCK switch, LUGGAGE COMPARTMENT switch, and PANIC switch.
   • This mechanical key works for the driver door, luggage compartment door and glove box, but cannot start the engine.

     A total of 7 electrical keys can be registered.

2. Oscillator (each door oscillator, front and rear indoor oscillator, luggage compartment inner oscillator, luggage compartment outer oscillator) Each oscillator transmits the request signal received from the certification ECU, and forms an electrical key detection area to detect the presence of an electrical key. The detection area formed by each door oscillator and luggage compartment outer oscillator is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of each door or 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 electrical key. During entry lock, the detection area is formed with the lock switch ON.
   • The detection area of the luggage compartment outer oscillator is formed when the power luggage door open switch is ON.
   • The detection area of the indoor oscillator (front and rear) is formed when the driver door is opened or closed, during start ignition, when a warning is activated, or when the lock switch is ON.
   • The detection area of the luggage compartment inner oscillator is formed when the luggage compartment door is closed or the luggage compartment open switch is pressed.

1. The smart access system with push-button start has the following functions:
   FUNCTION CHART
   
   

   Function	Outline
   Mechanical Key	Operation is the same as conventional mechanical key.
   Wireless Door Lock Control	This function remotely locks and unlocks all doors or luggage compartment. Operation is same as wireless door lock control system. However, the receiver in certification ECU uses entry door control receiver to control locking and unlocking.
   Entry Illumination	When person carrying electrical key enters detection area, door will enter unlock standby mode and front map light and door mirror foot light will illuminate.
   Entry Unlock	When electrical key is located in detection area of door oscillator, door will unlock by touching inside of outside door handle.
   Entry Unlock Mode Switching (See CUSTOMIZE PARAMETERS  )	Changes doors that can be unlocked with entry unlock function between 2 modes. Driver door mode All door mode
   Entry Lock	When electrical key is located in detection area of door oscillator and engine switch is off, door can be locked by pressing lock switch on outside door handle.
   Entry Luggage Compartment Open	When electrical key is in detection area of luggage compartment outer oscillator, luggage compartment opens by pressing luggage compartment open switch.
   Memory Call	This function operates driving position memory system in accordance with electrical key ID code.
   Electrical Key Lock-in Prevention	Prevents confinement of electrical key if door is locked using outside door handle while electrical key is still inside vehicle. If all doors locked are and luggage compartment door is closed while electrical key is still in luggage compartment, warning buzzer sounds. If luggage compartment open switch is operated, luggage compartment door can be opened.
   Warning	When any of situations below occur, smart access system with push-button start causes certification ECU to sound buzzer in combination meter and wireless door lock buzzer, and illuminate information in order to alert driver. Exit warning if shift lever position is not P and power source mode is not off (A/T). Exit warning if shift lever position is P and power source mode is not off (A/T). Warning if occupant leaves with electrical key. Warning if engine switch is operated while electrical key is outside actuation area. Warning if entry lock is operated while electrical key is inside vehicle. Warning if electrical key battery is weak.
   Battery Saving	If electrical key is constantly located within actuation area of door oscillator, system maintains periodic communication with electrical key. Therefore, if vehicle remains parked in that state for a long time, electrical key battery and vehicle battery could be drained.
   Key Cancel (See CUSTOMIZE PARAMETERS  )	Following electrical key functions can be cancelled by performing certain operations: Entry Unlock/Lock Memory Call Entry Luggage Compartment Open Electrical key Lock-in Prevention Warning
   Electrical Key Code Registration	The total number of electrical keys that can be registered is four. Enables the registration (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the Certification ECU.

Push the LOCK/UNLOCK/PANIC/LUGGAGE COMPARTMENT switch on the electrical key to operate each function. For details, (See SYSTEM DESCRIPTION  ).

1. The detection area is formed by communication between a door oscillator and door control receiver when the door is locked in order to detect access of the person carrying the electrical key.
2. When the person carrying the electrical key enters the detection area around the vehicle, the matching of the ID codes for a door oscillator and electrical key will automatically be performed. After the matching is completed, the door will enter unlock standby mode.
3. In unlock standby mode, the antenna 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 light blinks twice and the wireless door lock buzzer sounds twice.
4. If any of the doors are not opened after a door unlock operation, all doors will automatically lock after 30 seconds.

1. After leaving the vehicle carrying the electrical key, push the lock switch on the outside handle when all the doors are closed.
2. The certification ECU determines whether the electrical key is located inside or outside of the cabin based on the information from a door oscillator and room oscillator. Then matching of the ID codes is performed.
3. When the matching result shows that the ID codes of the electrical key and indoor antenna do not match and the ID codes of the electrical key and door oscillator match, the door lock function will operate. At this time, the hazard warning lights blink once and the wireless door lock buzzer sounds once.
4. If the electrical 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.

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

1. If you attempt to lock the door through keyless operation (move the lock knob to the lock position and then close the door) with the electrical key in the cabin, the system determines that the electrical key is located in the cabin and unlocks the door.
2. If the luggage compartment is closed with the electrical key in it, the alarm will sound and the luggage compartment can be opened only when all the doors are locked in order to prevent electrical key confinement in the vehicle.

When a person carrying the electrical key enters the detection area, the door will enter unlock standby mode and the front map light and door mirror foot light will illuminate.

HINT:

The entry illumination function operates when the electrical key enters the vehicle exterior detection area from out of the detection area. If the electrical key remains in the detection area for 3 seconds or more, the illumination function does not operate.

When the engine switch is off and the driver door courtesy light is off, opening the door will operate the memory call function (the door will move to a previously recorded driving position). Using the electrical key, memory call, electrical key registration and electrical key cancellation can be performed.
