Component Outline

Power switch


  • Transponder key amplifier

  • Turns on the power and starts the hybrid control system.

  • Contains a built-in transponder key amplifier to start the hybrid control system when the electrical key transmitter sub-assembly does not operate properly due to a depleted transmitter battery or wave interference.

No. 3 indoor electrical key antenna assembly (front floor)

No. 2 indoor electrical key antenna assembly (rear floor)

No. 1 indoor electrical key antenna assembly (inside luggage) (for RHD)

 Receives the request code from the certification ECU (smart key ECU assembly) and forms the vehicle interior detection area.
Power management control ECU

  • Changes the power source mode in 4 stages (off, on (ACC), on (IG), on (READY)) in accordance with the shift state and stop light switch.

  • Controls the push-button start function in accordance with signals received from switches and ECUs.

  • The power management control ECU and certification ECU (smart key ECU assembly) permit starting of the hybrid control system after receiving an unlock signal from the transmission control ECU assembly.
Certification ECU (smart key ECU assembly)

  • Performs key verification.

  • Controls the electrical key antenna (outside), electrical key antenna (indoor) and door lock/unlock sensor.

  • Forms the push-button start detection area.

  • Records codes for smart verification.
ID code box (immobiliser code ECU)

  • Receives command signals from the certification ECU and outputs immobiliser set and unset command signals to the power management control ECU.

  • Records codes for smart verification.
Transmission control ECU assembly

  • Locks/unlocks gearshift control based on lock/unlock request signals from the certification ECU (smart key ECU assembly).

  • Detects gearshift control lock/unlock status and transmits it to other ECUs.

  • Activates the shift control actuator based on signals from the power management control ECU when gearshift control is unlocked.

  • Controls the application timing of current to the parking lock motor based on signals from the rotation angle sensor.
Combination meter assembly

  • Operates various warnings (messages on the multi-information display, sounding of the buzzer in the combination meter assembly), according to the command signals from the certification ECU (smart key ECU assembly).

  • Outputs a vehicle speed signal to the main body ECU (multiplex network body ECU).
IG, ACC relay Turns on/off according to the power management control 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 power management control ECU.
Door control receiver Receives the 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.
