ENTRY AND START SYSTEM(for Start Function) SYSTEM DIAGRAM

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.

• 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 gearshift control lock/unlock command signals.

• Outputs immobiliser set/unset commands.

• Forms the smart key system detection area.

• Records codes for smart verification.

• 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.

• Permit starting of the hybrid control system after receiving an unlock signal from the hybrid vehicle control ECU.

• 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 certification ECU (smart key ECU assembly) when gearshift control is unlocked.

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

• 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).
