operate by merely carrying the electrical key This system consists primarily of the main body ECU, power switch, ID code box, steering lock ECU, electrical key, ACC relay, IG1 relay, IG2 relay and certification ECU The main body ECU controls the function This function operates in cooperation with the smart key system FUNCTION OF COMPONENT Component Function • • Power Switch • Transponder Key Amplifier • Electrical Key Receives signals from oscillators and returns ID code to door control receiver Electrical Key Oscillator • Console and Rear Seat Receives request signals from certification ECU and forms detection area in vehicle interior Steering Lock ECU Receives lock/unlock request signals from certification ECU and main body ECU Door Control Receiver Receives ID code from electrical key and transmits it to certification ECU • ST Transmits power switch signal to main body ECU Informs driver of power source mode or system abnormality with illumination of indicator light Receives ID code and transmits it to certification ECU when key battery is low Main body ECU • Changes power source mode in stages (off, on (ACC), on (IG), on (READY)) in accordance with shift position and state of stop light switch Controls push-button start function in accordance with signals received from switches and certification ECU and HV control ECU Certification ECU Certifies ID code received from door control receiver and transmits certification results to main body ECU Stop Light Switch Outputs state of brake pedal to main body ECU ID Code Box Receives steering unlock or engine immobiliser unset signals from certification ECU, certifies them, and transmits each unset signal to steering lock ECU or HV control ECU HV control ECU Receives signal from ID code box and main body ECU and performs HV control system is on (READY) SYSTEM FUNCTION The electric controls of the push-button start function are described below: Control Outline • Power switch control • Diagnosis When driver operates power switch with electrical key in driver's possession, certification ECU starts indoor electrical key oscillator, which transmits request signal to electrical key Upon receiving this signal, the electrical key transmits ID code signal to door control receiver Certification ECU verifies check results received from door control receiver and sends them to main body ECU Based on these results, main body ECU authorizes operation of power switch When main body ECU detects malfunction, main body ECU diagnoses and memorizes failed section ST–7 2AZ-FXE STARTING – SMART KEY SYSTEM Indicator Light B138023E01 CONSTRUCTION AND OPERATION (a) Power Switch The power switch consists of a momentary type switch, color (amber, green, greenish white) LEDs, and a transponder key amplifier • The greenish white LED is for illumination • The amber and green LEDs are for the indicator lights The driver can check the present power source mode and whether the HV control system can start in accordance with the illumination state of the indicator light • When the main body ECU detects an abnormality in the push-button start function, it makes the amber indicator light flash If the HV control system stopped in this state, it may not be possible to restart it (b) Indicator Light Condition Power switch indicator light condition: Power Source Mode/Condition Indicator Light Condition Brake pedal released Brake pedal depressed, shift lever in P off OFF ON (Green) (when key and vehicle IDs match) on (ACC, IG) ON (Amber) ON (Green) HV control system on (READY) OFF OFF Steering lock not unlocked Flashes (Green) for 15 sec Flashes (Green) for 15 sec System malfunction Flashes (Amber) for 15 sec Flashes (Amber) for 15 sec Brake Pedal Depressed (c) Main body ECU The main body ECU consists of the IG1 and IG2 relay actuation circuits and CPU HINT: Before removing the battery, make sure to turn the power switch off The main body ECU constantly stores the present power source mode in its memory Therefore, if the main body ECU is interrupted by disconnecting the battery, the main body ECU restores the power source mode after the battery is reconnected For this reason, if the battery is disconnected when the power switch is not off, the power will be restored to the vehicle at the same time the power is restored to the main body ECU (by reconnecting the battery) PUSH-BUTTON START FUNCTION OPERATION (a) This system has different power source mode patterns depending on the brake pedal condition and shift lever position Shift Lever Power Source Mode Pattern P position When the power switch is pushed once • off → HV control system on (READY) • on (ACC) → HV control system on (READY) • on (IG) → HV control system on (READY) ST ST–8 2AZ-FXE STARTING – SMART KEY SYSTEM Brake Pedal Shift Lever P position Not depressed Except P position Power Source Mode Pattern Each time the power switch is pushed • off → on (ACC) → on (IG) → off Each time the power switch is pushed • off → on (ACC) → on (IG) → on (ACC) - P position When the power switch is pushed with power source mode on (READY) • HV control system on (READY) → off - Except P position When the power switch is pushed with power source mode on (READY) • HV control system on (READY) → on (ACC) When the battery of the key is low, the push-button start function can be operated by holding the key against the power switch • After approximately hour has passed with the power switch on (ACC) and the shift position in P, the main body ECU will automatically cut the power supply (the power source mode changes to off) ST ST–9 2AZ-FXE STARTING – SMART KEY SYSTEM • The illustration below shows the transition of power source modes Transition of power source mode: Shift Position P Power Switch
