System Diagram [03/2017 - ]
| Component | Function |
|---|---|
| Front door outside handle assembly LH/RH | Sends request signals from the certification ECU (smart key ECU assembly) via the built-in electrical key antenna and forms the vehicle exterior detection area. Sends 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). |
| Indoor electrical key oscillator (front floor) No. 2 indoor electrical key oscillator (rear 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 oscillator (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 assembly | Sends switch operation signals to the certification ECU (smart key ECU assembly). |
| Door control receiver | Receives the smart key system code/ wireless code sent from the key and sends it to the certification ECU (smart key ECU assembly). |
| Wireless door lock buzzer | Sounds when warning functions operate in accordance with certification ECU (smart key ECU assembly) control. |
| Electrical key transmitter sub-assembly | Sends the ID code upon receiving a request signal. |
| Certification ECU (smart key ECU assembly) | Sends request codes to each electrical key antenna. Distinguishes and verifies the ID code from the key and sends signals to each ECU in response to operated functions (controls entire system). Performs encryption code communication with the steering lock ECU (steering lock actuator assembly) when ignition operations are performed.*1 Performs code communication with the ID code box (immobiliser code ECU) when ignition operations are performed.*2 |
