Entry And Start System (For Start Function) -- System Description



SYSTEM FUNCTION

Function
Outline
Push-button start function
When the electrical key transmitter sub-assembly is brought into the vehicle and verified, this function changes the power source or starts the engine when the engine switch and brake pedal*1 or clutch pedal*2 are operated.*3
Battery saving function for vehicle
When the vehicle is not used for a long time, this function extends the interval between each periodic transmission of the request signal, or stops transmission of the request signal to save battery power.
  1. When 5 days elapse without a response from the electrical key transmitter sub-assembly, periodic transmission stops.
  2. When 14 days elapse without a response from the electrical key transmitter sub-assembly, the lock/unlock sensors of all door outside handle assemblies except the driver door are disabled.
When the electrical key transmitter sub-assembly is left in a detection area for 10 minutes or more, the entry and start system automatically deactivates the exterior detection area the electrical key transmitter sub-assembly is in.
Transmitter battery saving function
  1. If the unlock switch of the electrical key transmitter sub-assembly is pressed twice while the lock switch is being pressed, the electrical key transmitter sub-assembly LED blinks 4 times and enters transmitter battery saving mode.
  2. Check that the entry and start system does not operate while in transmitter battery saving mode.
  3. To cancel transmitter battery saving mode, press a button of the electrical key transmitter sub-assembly.
Transmitter battery saving function for key
If a switch on the electrical key transmitter subassembly is depressed and held, this function stops transmission of the signal after approximately 20 seconds to save transmitter battery power..
Key cancel function
Cancels the entry and start system when certain operations are performed.
Immobiliser function
Allows the engine to be started only using registered electrical key transmitter sub-assemblies to prevent an unauthorized engine start.
Automatic power off function
for Automatic Transmission:
  1. When the shift lever is in P and the power source mode is on (ACC) (the engine has not been started and the vehicle is not moving), this function automatically turns off the power after approximately 20 minutes elapse.
  2. When the shift lever is in P and the power source mode is on (IG) (the engine has not been started and the vehicle is not moving), this function automatically turns off the power after approximately 60 minutes elapse.
for Manual Transmission:
  1. With the engine switch on (ACC) (the engine is not started and the vehicle is not moving), the power automatically turns off when the vehicle is left as is for 20 minutes or more.
  2. With the engine switch on (IG) (the engine is not started and the vehicle is not moving), the power automatically turns off when the vehicle is left as is for 60 minutes or more.
  1. *1: for Automatic Transmission
  2. *2: for Manual Transmission
  3. *3: If an emergency stop was performed (the engine switch was pressed quickly three times or more, or pressed and held for 2 seconds or more) while driving, the engine can be started again if driving at more than 10 km/h, by moving the shift lever to N and pressing the engine switch.

DETECTION AREA
NOTICE:
  1. Depending on the vehicle body shape, the electrical key transmitter sub-assembly may not operate in certain locations.
  2. Even if the electrical key transmitter sub-assembly is in the vehicle exterior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is near a window, door handle or the center of the rear bumper.
  3. Even if the electrical key transmitter sub-assembly is in the vehicle interior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is on the instrument panel, in the glove box or on the floor.
  4. Depending on the way the electrical key transmitter sub-assembly is held, the electrical key transmitter sub-assembly may not operate properly.
  5. The key detection area may reduce in size or the electrical key transmitter subassembly may not be properly detected under the following conditions:
    1. The transmitter battery is depleted.
    2. There are TV towers, electric power plants, broadcasting stations, gas stations or other facilities that generate strong radio waves or electrical noise nearby.
    3. The electrical key transmitter sub-assembly is covered by or in contact with a metal object.
    4. Electronic devices such as cell phones, etc. are carried with the electrical key transmitter sub-assembly.
    5. A radio wave type keyless entry system or wireless remote is operated nearby.
    6. The electrical key transmitter sub-assembly is placed near high-voltage equipment or equipment that emits electrical noise.

  1. The request signal sent from the certification ECU (smart key ECU assembly) is transmitted from each electrical key antenna (outside) to form the key detection area. The detection area formed by each electrical key antenna (outside) has a detection range of 0.7 to 1 m (2.30 to 3.28 ft.) from the door handles and rear bumper (electrical key antenna (outside luggage compartment)).

  2. When the vehicle is parked (the power source mode is off and the doors are locked*), the detection area of each electrical key antenna (outside) is formed by emitting a periodic request signal every 0.25 seconds in order to detect the electrical key transmitter sub-assembly. Also, when the doors are locked and a lock sensor is touched, a request signal is emitted, the detection area outside the vehicle is formed and the electrical key transmitter sub-assembly is detected.

    HINT:
    *: The entry and start system controls each door individually. After a door is locked with the door lock switch or wireless remote control function, a detection area is formed at the locked door even if all the doors are not locked.

  3. The detection area of the electrical key antenna (outside luggage compartment) is formed when the luggage door opening switch assembly is pressed.

  4. The detection area inside the vehicle is formed and the electrical key transmitter sub-assembly is detected when any of the following conditions are met: 1) The driver door is opened and closed, 2) the brake pedal*1 or clutch pedal*2 is depressed, 3) the engine switch is operated, 4) the conditions required for various warnings are met, or 5) an entry door lock operation is performed.

    1. *1: for Automatic Transmission
    2. *2: for Manual Transmission

  5. The detection area inside the vehicle when starting the engine can be customized through the customize function.
