Displays information when the smart access system with push-button start has a malfunction. Outputs a vehicle speed signal to the main body ECU. |
| Security indicator light | Blinks when the engine immobilizer system is set (the hybrid control system cannot be started) according to certification ECU (smart key ECU assembly) control (immobilizer function). |
| IG, ACC relay | Turns on/off according to power management control ECU control and provides power to each system. |
| Stop light switch assembly | Detects that the brake pedal has been depressed (switch is on) and outputs a signal to the power management control ECU. |
| Front door outside handle assembly LH/RH | Sends request signals from the door electrical oscillator via the built-in electrical key antenna and forms the vehicle exterior detection area. Door lock sensor operation signals to the certification ECU (smart key ECU assembly) (entry lock function). Uses the built-in touch sensor to detect the operation of the front door outside handle assembly and sends signals to the certification ECU (smart key ECU assembly) (entry unlock function). |
| Door electrical oscillator | Sends request signals from the certification ECU (smart key ECU assembly) to the electrical key antenna built into the front door outside handle assembly. |
| No. 1 indoor electrical key antenna assembly (front floor) No. 2 indoor electrical key antenna assembly (center floor) | Sends the request code from the certification ECU (smart key ECU assembly) and forms the vehicle interior detection area. |
| No. 3 indoor electrical key antenna assembly (inside luggage) | Sends the request code from the certification ECU (smart key ECU assembly) and forms the luggage compartment interior detection area. |
| Electrical key antenna (outside luggage) | Sends the request code from the certification ECU (smart key ECU assembly) and forms the luggage compartment exterior detection area. |
| Back door opener switch | Sends switch operation signals to the certification ECU (smart key ECU assembly). |
| Door control receiver | Receives the smart access system with push-button start code/ wireless code sent from the key and sends it to the certification ECU (smart key ECU assembly). |
| Electrical key | Sends the ID code upon receiving a request signal. |
CUSTOMIZE PARAMETERS
- CUSTOMIZE SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Start Function) HINT: The following items can be customized.

KEY ON Function that enables or disables the smart access system with push-button start. ON or OFF Certification ECU (smart key ECU assembly) Press and hold the DISP (steering pad switch assembly). The setting completion screen will be displayed. Return to the item selection screen. Entry cancel function (manual operation) NOTE: Because the key (for card type) does not have a wireless transmitter function, it cannot be used to change the entry unlock mode. HINT: While the smart access system with push-button start 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 power switch. The following functions are disabled when the smart access system with push-button start is canceled. Entry unlock/lock functions Push start function Key lock-in prevention function Entry warning functions When canceling the system through manual operation: Make sure the following conditions are met: The power switch is off. The driver door is closed. The driver door is unlocked. Press the unlock button of the key. Open the driver door within 5 seconds of completing the step above (driver door: closed at beginning of step --> opened). With the driver door open, press the unlock button of the key 2 times within 5 seconds of completing the step above. NOTE: If the driver door is closed before or while pressing the unlock button, the entry cancel setting mode will end. Close and open the driver door twice within 30 seconds of completing the above step (driver door: open at beginning of step --> closed --> opened --> closed --> opened). With the driver door open, press the unlock button of the key 2 times within 30 seconds of completing the step above. NOTE: If the driver door is closed before or while pressing the unlock button, the entry cancel setting mode will end. Close and open the driver door within 30 seconds of completing the step above (driver door: open at beginning of step --> closed --> opened). Close the driver door within 5 seconds of completing the above step. Check that the wireless buzzer sounds twice (short beeps) to confirm that the smart access system with push-button start has been canceled. Perform the following procedure to restore the smart access system with push-button start to the active state from the canceled state. Perform the procedures to cancel the smart access system with push-button start again. Check that the wireless buzzer sounds once (short beep) to confirm that the smart access system with push-button start 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 through manual operation 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.
