Buzzer
Play Sound Click on the button to play the sound. Please take note of the volume level.

The buzzer is a safety-related product. Audible alerts let you know when you lock or unlock the door, or close the powered sliding door, or put the car in reverse. The sound frequency and the number of repetitions differ by function so that the user can identify which function is operating just by hearing the buzzer sound.

CLOSE
Power Relay

Relays are switching devices that turn vehicle's electrical circuits on and off. When switched on, relays activate lamps, the starter, the horn, electromagnetic solenoids, motors, and various functions required for the car's operation. Dozens of relays are used in a single vehicle.

CLOSE
Solid State Relays

Solid state relays are switching devices that switch the vehicle's electrical circuits on and off, activating functions need for the car’s operation. Moreover, solid state relays can switch on and off rapidly and repeatedly, enabling adjustment of the lights’ brightness and motor speed, thus contributing to enhance the vehicle's functions.

CLOSE
High Voltage Relay

High voltage relays are switching devices for turning high voltage circuits on and off in electrically powered vehicles such as hybrid and electric vehicles. The contact remains switched on during regular driving, then is switched off when the vehicle is parked, isolating the high-voltage circuit from the rest of the vehicle to ensure safety.

CLOSE
Acoustic Vehicle Alerting System (AVAS)
Play Sound Click on the button to play the sound. Please take note of the volume level.

Electric or hybrid vehicles offer the advantage to being more silent than internal combustion engine vehicles. The AVAS alerts pedestrians to the car's approach with a simulated engine sound when the vehicle is traveling at low speeds. This contributes to the safety of pedestrians.

CLOSE
Body ECU

In addition to locking the doors when the vehicle speed reaches a set speed, the body ECU automatically controls the wipers when rain is detected and switches on lights in dark surroundings, and enables other functions that make driving more comfortable. This ECU also controls antitheft functions such as the immobilizer and security alarm.

CLOSE
Body ECU

Doors that lock when the vehicle reaches a certain speed, wipers that activate automatically when rain is detecting, lights that automatically switch on in darkened surroundings, and other such automatic controls contribute to more comfortable driving.

CLOSE
Air Conditioning ECU

The Air Conditioning ECU senses the vehicle's interior temperature as well as ambient air temperature, the amount of solar radiation, and other conditions. Based on these factors, controls the temperature of the air from the vents, vent opening, and blower air volume to maintain the cabin at the set temperature and provide a comfortable interior space for the passengers.

CLOSE
Sonar Sensor

The sonar sensor alerts the driver when the vehicle is close to an obstacle, facilitating parking and driving in tight spaces. The sensor also helps prevent or mitigate collisions caused by rapid acceleration after pedal misapplication.

CLOSE
Rain/Light Sensor

The rain/light sensor detects the amount of rain and light in the environment and automatically turns on and off the windshield wipers and headlights as needed. The sensor also recognizes the difference between beam bridges and tunnels. With this sensor, the light remains off when driving under an overpass like beam bridges while the light turns on early when driving through a tunnel.

CLOSE
ETC Device

The ETC device transmits signals to the antenna at an expressway toll gate. The device allows the driver to automatically pay the toll as the car drives through the toll gate without stopping.

CLOSE
Diagnostic Tester

The diagnostic tester is a tool to transmit signals to a car in order to run a diagnosis or perform basic inspections on electronic systems, that is used by car dealerships and service shops. The radio transmitter, oscilloscope, and other additional functions are available as options for customers who want a higher-function tester. By linking with a computer, you can perform multi-function diagnostic processes.
