      Actuation Area Detail
      Interior The interior actuation area of the indoor electrical key antennas (front, rear, inside luggage compartment) 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 front door electrical key antennas (LH, RH) and electrical key antenna (outside luggage compartment) is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside door handle or the center of the rear bumper.
      Around Front Doors The exterior actuation area of the door electrical key antennas 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 outside door handle, the actuation area is formed when the lock sensor is touched.
      Around Luggage Compartment Door The exterior actuation area of the electrical key antenna (outside luggage compartment) is formed when the luggage compartment door opening switch assembly is on.

  3. SYSTEM CONTROL


    1. Start Function


      1. The start function has different power source change patterns to suit the brake pedal state and shift lever position.

        Pattern Brake Pedal Shift Lever Position Power Source Change Pattern
        A Depressed P or N

        When the engine switch is pushed once.


        • Off → on (IG) (after the engine is started)
        B Not Depressed P

        Each time the engine switch is pushed.


        • Off → on (ACC) → on (IG) → off
        C Except P

        Each time the engine switch is pushed.


        • Off → on (ACC) → on (IG) → on (ACC)
        D - P

        When the engine switch is pushed in the on (IG) condition.


        • On (IG) (engine is started or not started) → off
        E - Except P

        When the engine switch is pushed in the on (IG) condition.


        • On (IG) (engine is started or not started) → on (ACC)
        B00832ME06

        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 assembly, the engine may not start when the engine switch is pushed with the brake pedal 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 or when the shift lever is in any position other than P or N.

    2. Cranking Hold Function


      1. Once the engine switch is pressed, this function operates the starter until the engine starts, provided that the brake pedal is depressed. This prevents application of the starter for an inadequate length of time and it also prevents the engine from being cranked after it has started. For details, see for 2AR-FE, for A25A-FKS and Click here for 2GR-FKS.

    3. Entry Unlock


      1. When the electrical key transmitter sub-assembly is in the actuation area formed by the door electrical key antenna and the driver door outside handle assembly is held, touching the built-in touch sensor unlocks the driver door. Continuing to touch the built-in touch sensor for 2 seconds or more unlocks all the doors. If the front passenger side door outside handle assembly is held, touching the built-in touch sensor unlocks all of the doors. (Driver door unlock mode)

      2. When the electrical key transmitter sub-assembly is in the actuation area formed by the door electrical key antenna, holding any of the front door outside handle assembly RH or LH and touching the built-in touch sensor unlocks all the doors. (All door unlock mode)

      3. When the doors unlock, the hazard warning lights flash twice and the buzzer sounds twice as an answer back.

        Tech Tips

        If the doors are locked by wireless operation, the smart entry and start system or key linked power door lock operation, it may not be possible to unlock the doors using the smart entry and start system. In this situation, use the wireless function of the electrical key transmitter sub-assembly to unlock the doors.
