    1. Electrical Key Transmitter Sub-assembly


      1. The key consists of a mechanical key, a transmitter for the wireless door lock control and a transceiver for the entry and start system.

      2. The transceiver for the entry and start system receives the signals from the electrical key antenna and returns the ID code to the door control receiver.

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

      4. When the key battery is low, the radio wave response received from the engine switch is returned to the engine switch by the key.

      5. This mechanical key works for the driver's door, but cannot be used to start the engine.

    2. Engine Switch (Push Start Switch)


      1. The engine switch consists of a momentary type switch, illumination, antenna coil, and transponder key amplifier.

        B001C06

    3. Certification ECU (Smart Key ECU Assembly)


      1. The certification ECU consists of the IG1 and IG2 relay 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 the IG1 and/or IG2 relay actuation circuits during driving.

        B001BI7E01

        Tech Tips

        The certification ECU constantly stores the present power source mode in its memory. Therefore, if the power to the certification ECU is interrupted due to the removal of the battery, the certification ECU restores the power source mode after the battery is reconnected. For this reason, if the battery is removed when the engine switch is in any position other than off, the power will be restored to the vehicle at the same time the power is restored to the certification ECU (by reconnecting the battery).
