| Steering lock actuator assembly (steering lock ECU) | Receives command signals from the certification ECU and activates the steering lock actuator assembly. Records codes for smart verification. |
| Combination meter | Operates various warnings (messages on the multi-information display, sounding of the buzzer in the combination meter, blinking or illumination of the master warning light) according to the command signals from the certification ECU. Displays information when the smart access system with push-button start has a malfunction. Outputs a vehicle speed signal to the main body ECU. |
| Security indicator light | Blinks when the engine immobiliser system is set (the engine cannot be started) according to certification ECU control (immobiliser function). |
| IG, ACC relay | Turns on/off according to power management control ECU control 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. |
| Turn signal flasher assembly | Blinks the hazard warning lights during answer back according to main body ECU control (answer back function). |
| Front door outside handle assembly LH/RH | Sends request signals from the door electrical oscillator via the built-in electrical key antenna and forms the vehicle exterior detection area. Sends door lock switch operation signals to the certification ECU (entry lock function). Uses the built-in touch sensor to detect the operation of the front door outside handle assembly and sends signals to the certification ECU (entry unlock function). |
| Door electrical oscillator | Sends request signals from the certification ECU to the electrical key antenna built into the front door outside handle assembly. |
| No. 1 indoor electrical key antenna assembly (front floor) No. 2 indoor electrical key antenna assembly (rear floor) | Sends the request code from the certification ECU and forms the vehicle interior detection area. |
| No. 3 indoor electrical key antenna assembly (inside luggage) | Sends the request code from the certification ECU and forms the luggage compartment interior detection area. |
| Electrical key antenna (outside luggage) | Sends the request code from the certification ECU and forms the luggage compartment exterior detection area. |
| Back door electrical key switch | Sends switch operation signals to the certification ECU. |
| Door control receiver | Receives the smart access system with push-button start code/ wireless code sent from the key and sends it to the certification ECU. |
| Wireless door lock buzzer | Sounds when performing answer-back or when warning functions operate in accordance with certification ECU control. |
| Electrical key | Sends the ID code upon receiving a request signal. |
| Certification ECU | Sends request codes to each electrical key antenna. Distinguishes and verifies the ID code from the key and sends signals to each ECU in response to operated functions (controls entire system). Performs encryption code communication with the ID code box when ignition operations are performed. |
SYSTEM DESCRIPTION
- PRECAUTION FOR REGISTRATION If replacing any of the following parts, refer to the registration procedures. Refer to «REGISTRATION»(ref-524134-S05166328262013012800000) . ID code box Certification ECU Steering lock actuator assembly (steering lock ECU) ECM Electrical key transmitter (key)
- SYSTEM FUNCTION Function Outline Ignition function When the key is brought into the vehicle and verified, this function changes the power source or starts the engine when the engine switch and brake pedal are operated. Battery saving function for vehicle When the vehicle is not used for a long time, this function extends the interval between each periodic transmission of the request signal, or stops transmission of the request signal to save vehicle battery power. When 5 days elapse without a response from the key, periodic transmission stops. When 14 days elapse without a response from the key, the lock/unlock sensor of all door outside handle assemblies except the driver side door is disabled. When the key is in the detection area outside the vehicle for 10 minutes or more, this functions stops the periodic transmission of the request signal (formation of the detection area) to save battery power. Battery saving function for key If a switch on the key is depressed and held, this function stops transmission of the signal after approximately 20 seconds to save key battery power. Key cancel function Cancels the smart access system with push-button start when certain operations are performed. Immobiliser function Allows the engine to be started only using registered keys to prevent an unauthorized engine start. Automatic power off function With the shift lever in P and the engine switch on (ACC) or on (IG) (the engine is not started and the vehicle is not moving), the power automatically turns off when the vehicle is left as is for 60 minutes or more.
- DETECTION AREA NOTE: Depending on the vehicle body shape, the key may not operate in certain locations. Even if the key is in the vehicle exterior key detection area, the key may not be properly detected if the key is near a window, a door handle or the center of the rear bumper. Even if the key is in the vehicle interior key detection area, the key may not be properly detected if the key is on the instrument panel, in the glove box or on the floor. Depending on the way the key is held, the key may not operate properly. The key detection area may reduce in size or the key may not be properly detected under the conditions below: The key battery is depleted. There are TV towers, electric power plants, broadcasting stations, gas stations or other facilities that produce strong electric waves nearby. Wireless products such as cell phones, etc. are carried with the key. The key is covered by or in contact with a metal object. Electric wave-type keyless entry systems are being operated nearby. The key is placed near high-voltage equipment or equipment that emits electrical noise. The request signal sent from the certification ECU is transmitted from each electrical key antenna (outside) to form the smart key detection area. The detection area formed by each electrical key antenna (outside) has a detection range of 0.7 to 1 m (2.30 to 3.28 ft.) from the door handles and rear bumper (electrical key antenna [outside luggage]). When the vehicle is parked (the power is off and the doors are locked*), the detection area of each electrical key antenna (outside) is formed by emitting a periodic request signal every 0.25 seconds in order to detect the key. Also, when the doors are locked and a lock sensor is touched, a request signal is emitted, the detection area outside the vehicle is formed and the key is detected. HINT: *: The smart access system with push-button start controls each door individually. After a door is locked with the door lock switch or wireless remote control function, a detection area is formed at the locked door even if all the doors are not locked. The detection area of the electrical key antenna (outside luggage) is formed when the back door opener switch is pressed. The detection area inside the vehicle is formed and the key is detected when any of the following conditions are met: 1) The driver side door is opened and closed, 2) the brake pedal is depressed, 3) the engine switch is operated, 4) the conditions required for various warnings are met, or 5) a smart door lock operation is performed. The detection area inside the vehicle when starting the engine can be customized through the customize function.
