THEFT DETERRENT / KEYLESS ENTRY SMART ENTRY AND START SYSTEM(for Start Function) SYSTEM DIAGRAM
| Component | Outline |
|---|---|
| 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 entry door lock/unlock commands. ·
Outputs steering lock ECU (steering lock actuator assembly) lock/unlock command signals. ·
Outputs immobiliser set/unset commands. ·
Forms the smart entry and start system detection area. |
| 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 ECU (steering lock actuator assembly). ·
Records codes for smart verification. |
| Combination meter assembly | ·
Operates various warnings (messages on the multi-information display and sounding of the buzzer in the combination meter) according to the command signals from the certification ECU (smart key ECU assembly). ·
Outputs a vehicle speed signal to the certification ECU (smart key ECU assembly). |
| 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*1 | Detects that the brake pedal has been depressed (switch is on) and outputs a signal to the certification ECU (smart key ECU assembly). |
| Clutch start switch assembly*2 | Detects that the clutch pedal has been depressed (switch is on) and outputs a signal to the certification ECU (smart key ECU assembly). |
| Park/neutral position switch assembly*1 | Outputs the shift position to the certification ECU (smart key ECU assembly) |
| Transmission floor shift assembly*1 | Outputs a shift signal to the certification ECU (smart key ECU assembly). |
| 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 assembly) and forms the vehicle interior detection area. |
| Door control receiver | Receives the smart entry and start system 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. |
