CUSTOMIZE PARAMETERS [12/2013 - ]
- CUSTOMIZE SMART KEY SYSTEM (for Start Function) Customizing with the Techstream NOTE: When the customer requests a change in a function, first make sure that the function can be customized. Be sure to make a note of the current setting before customizing. When troubleshooting a function, first make sure that the function is set to the default setting. HINT: The items in the table below can be customized. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical / Smart Key or Main Body / Utility / Customize / Smart Key or Warning. Select the setting by referring to the table below. SMART KEY Display Default Content Setting Relevant ECU Ignition Available Area All Function that sets the area that the key must be in before the engine switch can be operated. Front or All Certification ECU (smart key ECU assembly) Engine Start Indicator ON Function to Turn ON / OFF of the Engine Start Indicator. OFF or ON Certification ECU (smart key ECU assembly) Auto Entry Cancel SW OFF Function that enables or disables the smart key system. OFF or ON Certification ECU (smart key ECU assembly) WARNING Display Default Content Setting Relevant ECU Key Low Battery Warning ON Function that enables or disables the sounding of the buzzer when the key battery is low and the engine switch is turned off after being on (IG) for 20 minutes or more. OFF or ON Certification ECU (smart key ECU assembly) Entry cancel function (manual operation) HINT: While the smart key system is canceled, it is possible to lock and unlock the doors with the wireless operation, and the start system can be operated by holding the key against the engine switch. The following functions are disabled when the smart key system is canceled. Entry unlock/lock functions Entry ignition function Key lock-in prevention function Entry luggage compartment door open function Entry warning functions Canceling the system operation: Make sure the following conditions are met: The engine switch is off. The driver side door is closed. The driver side door is unlocked. Press the unlock switch of the electrical key transmitter sub-assembly. Open the driver side door within 5 seconds of completing the step above (driver side door: closed at beginning of step --> opened). With the driver side door open, press the unlock switch of the electrical key transmitter sub-assembly 2 times within 5 seconds of completing the step above. NOTE: If the driver side door is closed before or while pressing the unlock switch, the entry cancel setting mode will end. Close and open the driver door twice (driver door: open --> closed --> opened --> closed --> opened). With the driver door open, press the unlock switch of the electrical key transmitter sub-assembly 2 times. NOTE: If the driver side door is closed before or while pressing the unlock switch, the entry cancel setting mode will end. Close and open the driver door (driver door: open --> closed --> opened). Close the driver side door within 5 seconds of completing the above step. Check that the wireless buzzer sounds twice (short beeps) to confirm that the smart key system has been canceled. HINT: Finish steps 5 to 7 within 30 seconds. Perform the following procedure to restore the smart key system to the active state from the canceled state. Perform the procedures to cancel the smart key system again. Check that the wireless buzzer sounds once (short beep) to confirm that the smart key system has been restored to the active state. HINT: The system changes between the canceled state and the active state each time the procedure to cancel the system is performed. The buzzer sounds twice when the system changes from the active state to the canceled state, and sounds once when the system changes from the canceled state to the active state.
