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.

• 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 entry and start system function in accordance with signals received from switches and ECUs.

• Permits the steering lock ECU (steering lock actuator assembly) to supply power to activate the motor. The certification ECU (smart key ECU assembly) permit starting of the hybrid control system after receiving an unlock signal from the steering lock actuator assembly (steering lock ECU).

• Performs key verification.

• Controls the electrical key antenna (indoor).

• Outputs steering lock ECU (steering lock actuator assembly) lock/unlock command signals.

• Outputs immobiliser set/unset commands.

• Forms the vehicle interior detection area.

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

• Records codes for smart verification.

• 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.

• Displays various warnings (messages on the multi-information display) according to the command signals from the certification ECU (smart key ECU assembly).

• Outputs a vehicle speed signal to the ECUs.
