ENTRY AND START SYSTEM(for Start Function) SYSTEM DIAGRAM

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.

• Receives the entry and start system code/wireless code sent from the electrical key transmitter sub-assembly.

• Performs key verification.

• Controls the electrical key antenna (indoor).

• 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 entry and start system detection area.

• Records codes for smart verification.*1

ID code box (immobiliser code ECU)*2

• Receives command signals from the certification ECU (smart key ECU assembly) 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 assembly) when starting the engine.

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 (blinking or illumination of the smart warning light, and sounding of the buzzer in the combination meter assembly) according to the command signals from the certification ECU (smart key ECU assembly).

• Displays information or operates LEDs when the entry and start system is malfunctioning.

• Outputs a vehicle speed signal to the ECUs.

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*3

Detects that the brake pedal has been depressed (switch is on) and outputs a signal to the certification ECU (smart key ECU assembly).

Park/neutral position switch assembly*3

Outputs the shift position to the certification ECU (smart key ECU assembly).

Clutch start switch assembly*4

• No. 2 indoor electrical key antenna assembly (center pillar LH)

• No. 2 indoor electrical key antenna assembly (center pillar RH)

• No. 1 indoor electrical key antenna assembly (front floor)

• No. 1 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.

Electrical key transmitter sub-assembly

Sends the ID code upon receiving a request signal.
