      A0116RDE01

      1. Actuation Area

    Actuation Area Details
    Interior The interior actuation area of the indoor electrical key oscillators (front, rear) is formed when the driver door is opened or closed, when the engine switch is pressed, when a warning is activated, or when the lock sensor is on, when the brake pedal (CVT) is press or when the clutch pedal (M/T) is pressed.
    Exterior The exterior actuation area formed by the door electrical key oscillators (LH, RH) and outside electrical key oscillator (back door) is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of the front doors, or the center of the rear bumper.
    Front Door Around The exterior actuation area of the door electrical key oscillators (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 proximity of a key. When locking the door using the lock switch on the outer door handle, the actuation area is formed when the lock switch is pressed.
    Back Door Around

    • The exterior actuation area of the outside electrical key oscillator (back door) is formed when the back door opener switch is on.

    • The exterior actuation area of the outside electrical key oscillator (back door) is formed when the back door lock switch is on.

        Function Outline
        Wireless Door Lock Control This function is a convenient system for locking and unlocking all the doors at a distance. The operation of this function is the same as that in the wireless door lock control system.
        Entry Illumination When a key enters the exterior actuation area of door electrical key oscillators (LH and RH) the personal light illuminate.
        Entry Unlock When a key is located in the exterior actuation area of any electrical key oscillator (driver, front passenger, or back door) and the engine switch is OFF, all doors can be unlocked by simply touching the unlock sensor.
        Entry Lock When a key is located in the exterior actuation area of any electrical key oscillator (driver, front passenger, or back door) and the engine switch is OFF, all doors can be locked by simply touched the lock sensor or pressing the back door lock switch.
        Back Door Open When a key is in an exterior actuation area of the outside electrical key oscillator (back door), the back door opens manually by simply pressing the back door opener switch.
        Prevention of Key Confinement The key confinement prevention function prevents the key from being locked inside the vehicle. This function operates in 2 different situations: keyless lock, lock sensor.
        Warning When any of the situations below occur, the entry and start system causes the smart key ECU assembly to sound the buzzer in the combination meter assembly and the wireless door lock buzzer in order to the alert the driver.
        Battery Saving If the key remains within the exterior actuation area of any electrical key oscillator (driver, front passenger, or back door), the system maintains periodic communication with key. 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 cancelled by following certain procedures.

        • Entry Unlock/Lock

        • Repeat open → close once for the driver door within 30 seconds, and open again (Driver Door: Open → Close → Open).

        • Close the driver door within 5 seconds.

          When key cancel is activated, the wireless door lock buzzer sounds once. To return to the original condition, perform the procedures again. When key cancel is returned, the wireless door lock buzzer sounds twice.

    4. Key Code Registration Function

      The table below shows the three special coded ID registration function modes through which up to seven different codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM. For details of the recognition code registration procedure, refer to the Repair Manual.

      Mode Function
      Rewrite Erases all previously registered codes and registers only the newly received codes. This mode is used whenever a transmitter or the integration relay is replaced.
      Add Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter.
      Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.

  5. CONSTRUCTION


    1. Key


      1. The key consists of a mechanical key, transmitter for the wireless door lock control, transceiver for the entry function and transponder chip for the engine immobiliser function.

      2. This mechanical key operates the driver door lock cylinder, but cannot be used to start the engine. When the mechanical key is used, the cap of the driver door lock cylinder must be removed.

      3. The transmitter for the wireless door lock control has a LOCK button and UNLOCK button.

      4. The transceiver of the key receives the signals from the oscillators and returns the ID code to the door control receiver.

      5. The transponder chip for the engine immobiliser function returns a signal to the engine switch as a response to the radio wave it received from the engine switch.

        *3 UNLOCK Button - -

    2. Engine Switch


      1. The engine switch consists of a momentary type switch, indicator light (amber and green color LEDs), illumination, antenna coil and transponder key amplifier.

      2. The driver can determine the present power source and check whether the engine can start or not in accordance with the illumination state of the indicator light.

      3. When the power management control ECU detects an abnormality with the entry and start system, it makes the amber indicator light flash. If the engine is stopped in this state, it might not be possible to restart it.

  6. DIAGNOSIS


    1. Start Function


      1. The power management control ECU and smart key ECU assembly can detect malfunction in the entry and start system when the power source is in the IG-ON mode.

      2. When the ECUs detect a malfunction, the amber indicator light of the engine switch flashes to warn the driver. At the same time, the ECUs store 5-digit Diagnostic Trouble Code (DTC) in their memories.

      3. The indicator light warning continues for 15 seconds even after the engine switch is switched to OFF.

      4. The 5-digit DTCs can be read after connecting an intelligent tester II to DLC3.

      5. The entry and start system may not operate successfully if a malfunction occurs.
