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 key 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 entry door lock/unlock commands.
- Outputs steering lock actuator assembly lock/unlock command signals.
- Outputs immobiliser set/unset commands.
- Forms the entry function detection area.
|
| ID code box (immobiliser code ECU) |
- Receives command signals from the certification ECU (smart key ECU) and outputs immobiliser set and unset command signals to the ECM.
- Records codes for smart verification.
|
| ECM |
- Outputs a signal indicating that the engine has started to the certification ECU (smart key ECU) when starting the engine.
|
| Steering lock ECU (steering lock actuator assembly) |
- Receives command signals from the certification ECU (smart key ECU) 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).
- 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) 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). |
No. 1 indoor electrical key antenna assembly (front floor)
No. 2 indoor electrical key antenna assembly (rear floor) |
Sends the request code from the certification ECU (smart key ECU) 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 key and sends it to the certification ECU (smart key ECU). |
| Electrical key transmitter sub-assembly |
Sends the ID code upon receiving a request signal. |
