In the era of rapid development of science and technology, the configuration and functions of cars have undergone great changes and become more and more outstanding. But there are some features that drivers don't understand, like the fact that if an airbag is accidentally turned off, there's no protection in the event of a crash. And if the electronic handbrake is confused, there will be very serious consequences, so we must pay attention to these conditions. So whether your car is expensive or not, don't waste that OBD hole under the steering wheel that many people don't know about.

       This is a place where you can connect to a dedicated device and have a comprehensive understanding of the vehicle's operating data. It might not have been important before, but this year it will be after November. If it is after the addition of OBD detection, both the running state of the car and the faults are very worthy of our attention. If there are friends who buy used cars, this can be more helpful, after all, as long as the change of the dashboard, gearbox and other important parts, can be seen directly, which will solve the problem of buying an accident car or a refurbished car.

       Of course, whether it is the replacement of spare parts at ordinary times or the timely detection of vehicle operation, it is possible to know the specific situation. In the annual inspection can also help us through, or can reduce unnecessary trouble.

Plus this year's annual inspection will be used, so we must have a concept. If you have the chance, you can make a test yourself and also make a rest according to the condition of the car.
