        The operation procedure is as follows:

        - Press the unlock button of the electrical key transmitter sub-assembly once.

        - Within 5 seconds of the step above, open the driver door (Driver Door: Close→Open).

        - Within 5 seconds of the step above, press the unlock button of the electrical key transmitter sub-assembly twice.

        - Repeat close → open for the driver door twice* (Driver Door: Open → Close → Open → Close → Open).

        - Press the unlock button of the electrical key transmitter sub-assembly twice.*

        - Repeat close → open for the driver door once* (Driver Door: Open → Close → Open).

        - Within 5 seconds of the step above, close the driver door.

        When the cancel procedure is complete, the buzzer sounds twice. Meanwhile, when the procedure is performed again to resume the system, the buzzer sounds once.

        *: Perform all these 3 steps within 30 seconds of the previous step.

    10. Key Code Registration Function


      1. The table below shows the 4 special ID code registration function modes through which up to 7 different codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM. For details, refer to the Repair Manual.

        Mode Function
        Rewrite Clears all previously registered codes and registers only the newly received codes. This mode is used whenever a key is replaced.
        Add Adds a newly received code while preserving previously registered codes. This mode is used when adding a new key.
        Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.
        Prohibit To clear all the registered codes and to prohibit the wireless door lock control function. This mode is used when a key is lost.

  5. CONSTRUCTION


    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, but cannot be used to start the hybrid control system. 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 panic switch.

      4. The transmitter for the remote air conditioning system for plug-in HV has a remote air conditioning system switch.

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

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

        *5 Mechanical Key - -

    2. Power Switch


      1. The power 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 hybrid control system 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 start function, it makes the amber indicator light flash. If the hybrid control system is stopped in this state, it might not be possible to restart it.

        On (READY) OFF
        Start Function Malfunction Flashes (Amber) for 15 seconds

  6. DIAGNOSIS


    1. When the power management control ECU and certification ECU (smart key ECU assembly) detects a malfunction in the entry and start system, the amber indicator light of the power switch flashes to warn the driver. At the same time, the ECUs store 5-digit Diagnostic Trouble Codes (DTC).

    2. The indicator light warning continues for 15 seconds even after the power switch is turned to off.

    3. The 5-digit DTCs can be read by connecting the Global Tech Stream (GTS) to the DLC3. For details, refer to the Repair Manual.
