Engine switch
- Transponder key amplifier
|
- Turns on the power and starts the engine.
- Contains a built-in transponder key amplifier to start the engine when the electrical key transmitter sub-assembly does not operate properly due to a depleted battery or wave interference.
|
| Certification ECU (smart key ECU assembly) |
- Changes the power source mode by operating the ACC and IG relays.
- Controls starting by operating the starter relay.
- Performs key verification.
- Controls the electrical key antenna (outside), electrical key antenna (indoor) and door lock/unlock sensor.
- Outputs smart entry door lock/unlock commands.
- Outputs steering lock actuator assembly lock/unlock command signals.
- Outputs immobiliser set/unset commands.
- Forms the smart entry detection area.
- Records codes for smart verification.
|
| ECM |
- Outputs a signal indicating that the engine has started to the certification ECU (smart key ECU assembly) when starting the engine.
|
| ID code box (immobiliser code ECU) |
- Receives command signals from the certification ECU and outputs immobiliser set and unset command signals to the ECM.
- Records codes for smart verification.
|
| Steering lock ECU (steering lock actuator assembly) |
- Receives command signals from the certification ECU (smart key ECU assembly) and activates the steering lock actuator assembly.
- Records codes for smart verification.
|
| Combination meter assembly |
- Operates various warnings (messages on the multi-information display, sounding of the buzzer in the combination meter, blinking or illumination of the smart warning light) according to the command signals from the certification ECU (smart key ECU assembly).
- Displays information or operates LEDs when the smart access system with push-button start has a malfunction.
- Outputs a vehicle speed signal to the main body ECU (multiplex network body ECU).
|
| IG, ACC relay |
Turns on/off according to the certification ECU (smart key ECU assembly) 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 certification ECU (smart key ECU assembly). |
No. 1 indoor electrical key antenna assembly (front floor)
No. 1 indoor electrical key antenna assembly (rear floor) |
Sends the request code from the certification ECU (smart key ECU assembly) and forms the vehicle interior detection area. |
| Door control receiver |
Receives the smart access system with push-button start code/wireless code sent from the electrical key transmitter sub-assembly and sends it to the certification ECU (smart key ECU assembly). |
| Electrical key transmitter sub-assembly |
Sends the ID code upon receiving a request signal. |
