OBD-II CONNECTION STANDARD ON LIVING VEHICLES
Oct
Most vehicles today use high-end computers to control and operate a system called an ECU (or black box). This system performs management and monitoring, for more advanced vehicles, it will control and operate the vehicle, give warnings and indicators for the driver to know the abnormalities of the vehicle through the clock, the screen on the taplo from there to take the initiative or ask the manufacturer or a specialist unit to intervene.
Older brother Nguyen Tue Van (1983) – Bachelor of Information Technology (IT) – is a technologist knowledgeable about mechanical, electrical and electronic engineering, since 2010 he has learned and successfully tested a number of products and applications. Use to check, read, delete, analyze and warn for some high-end vehicles using OBD II connection standard. He often shares and exchanges knowledge, tests, free checks, analyzes and deletes errors on a number of domestic and foreign forums to support the community of private vehicle users.

OBD II connection port
He shared: OBD-II stands for the phrase "On-board diagnostics II" which can be understood as "Second-generation diagnostic connection standard" or "Second generation on-board diagnostics" This port has On most vehicles manufactured from 2004 onwards, it is usually arranged under the steering wheel of the vehicle in the form of a trapezoid with 16 connecting pins.

ECU connection device
Connecting devices (reading, diagnosing, deleting, editing...depending on the manufacturer's input features) according to the OBD-II connection standard and the processor chip can be understood as an interpreter chip, most of the devices are using ELM (Extreme Learning Machine) chips. In essence, it is responsible for connecting to the ECU (Black box / vehicle computer) and interpreting the language of the ECU for software that is a computer or mobile TB connected via a connection cable (USB / Type C) or Bluetooth connection with TBs equipped with an operating system equivalent to a laptop/mobile device to perform the tasks of reading errors, diagnosing errors, deleting and fixing errors or writing, loading and upgrading operating systems for car. These TBs are offered by a number of companies with prices ranging from 10$ to several thousand USD depending on the performance of each device or manufacturer.

Dedicated software to connect, display and intervene ECU
To connect and use on computers/mobile devices/Tablets, users need to purchase more or download free applications corresponding to the operating system being used at App Store, Play Store, currently. I am using Scan XL Professional software.
Through the software, you can have all the system information of the vehicle, control the vehicle's operating functions, designed utility features. For specialized software that can customize, upgrade or adjust the limited features provided with the vehicle or simulate the vehicle's operating system, thereby diagnosing the performance, predicting the damage of the vehicles. parts, upgrade the ECU system, fix and clear the error after fixing the hardware.
With these shares, perhaps it will help young people who are regularly using 4-wheelers to approach, understand and take better care of their clumsy "second wife"!
