      Actuation Area Detail
      Interior The interior actuation area of the indoor electrical key oscillators (front, center, rear) is formed when the driver door is opened or closed, when the engine switch is pushed, when a warning is activated, or when the lock sensor is on.
      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.
      Around Front Door 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 sensor on the outer door handle, the actuation area is formed when the lock sensor is touched.
      Around Back Door The exterior actuation area of the outside electrical key oscillator (back door) is formed when the back door opener switch is on.

  3. FUNCTION


    1. 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 Click here.

  4. SYSTEM CONTROL


    1. Start Function


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

    1. Electrical Key Transmitter Sub-assembly


      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 and glove box 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 switch, unlock switch, and power back door switch.

      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.

    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 smart 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.

    3. Power Management Control ECU


      1. The power management control ECU consists of the IG relay No. 1 and No. 2 actuation circuits, CPU, and hold circuit.

      2. The hold circuit is installed to prevent the power supply to the relays from being cut off when an abnormality occurs in IG Relay No. 1 and/or No. 2 actuation circuits while driving.

        A01F0NHE08

        Tech Tips

        The power management control ECU constantly stores the present power source state in its memory. Therefore, if the power to the power management control ECU is interrupted due to the removal of the battery, the power management control ECU restores the power source after the battery is reconnected.

        For this reason, if the battery is removed when the engine switch is in a mode other than off, the power will be restored to the vehicle at the same time the power is restored to the power management control ECU (by reconnecting the battery).

        Therefore, before removing the battery, be sure to turn the engine switch off.

  6. DIAGNOSIS


    1. Start Function


      1. The power management control ECU and certification ECU (smart key ECU assembly) can detect a malfunction in the smart entry and start system when the power source is on (IG).

      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 a 5-digit Diagnostic Trouble Code (DTC) in their memories.

      3. The indicator light warning continues for 15 seconds even after the engine switch is turned off.

      4. The 5-digit DTCs can be read after connecting the Global TechStream (GTS) to the DLC3.

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