How do you use a car diagnostic tool

Roman Cyrus December 07, 2020 Gadget Leave a Comment

It is a device for self-diagnosis and reporting of your car, which can also be used on trucks. Unlike OBD systems, this device can be used on all cars and trucks, whatever the make or model. The OBD 2 system became mandatory in the United States of America starting from 1994, while in Europe in 2000 for petrol cars and 2003 for diesel cars.

How do you use a car diagnostic tool?

The data that all OBD 2 devices can control are those relating to your car’s polluting systems, such as the catalyst or the lambda probe. However, it is not certain that it is possible to check the other systems present on the car, such as the status of the airbags or the air conditioner’s health. It is possible that to carry out these checks, equipment specially made for the make and model of that car is required.

There are mere code readers on the market, inexpensive and easy-to-use OBD 2 devices that are only and exclusively useful for reading codes and erasing them. In short, performance is limited, as is access to the data of one’s car.

Those who want to access more data and want to get some troubleshooting guidelines should consider proper scanning tools. They are more expensive, it is true, but they are also very performing, capable of displaying data in real-time as well as those that have been recorded by the car’s ECU over time. They are tools that allow you to carry out bidirectional tests, check the engine transmission data, and verify the data from practically every sensor on the car.

Features to consider when buying

Today, dozens and dozens of car diagnosis tools are available on the market, so many can understand which are the best models that could be complex. Here is a list of features that might be useful to you:

1. Variety of readings

Scanners that allow you to get almost unlimited access to car data are considered better than those with limited access. It is possible to check every detail of the car and receive information on how to solve it.

2. Dimensions

Unlike what you might think, car diagnosis tools come in many different sizes. It is always better to choose a compact model to be carried with you without any difficulty.

3. Archiving functionality

The best models have this functionality. That is, they can keep track of all the readings that have been made over time.

4. Data reading and recording methods

Some scanner models have an LCD for reading data. They are comfortable, as it is not necessary to download any application and can therefore be used even if you do not have your smartphone with you or do not have it at all. Alternatively, you can opt for scanners with a Bluetooth connection. They do not have a display, but they connect to the smartphone or tablet. The great thing is that they allow you to record data without difficulty, which some models with displays do not offer. They also allow access to extra features, such as the ability to always have the car’s reports with you, view old readings, and access graphs.

5. Wi-Fi connection

Some scanners can connect to the web via Wi-Fi, so you can update your car diagnostics software easily and in just a few clicks. An update of this type allows you to add the new car models introduced on the market and eliminate bugs. It is also possible to add diagnostic tools to obtain more excellent performances ever.

6. Power supply

The best scanners for car diagnostics do not need batteries or a connection to the electrical network to function. They connect directly to the connector of your car. However, they must have a special technology that allows you to prevent the car battery from being discharged during use.

Car diagnosis tools: who are they useful for?

The tools for diagnosing your car are useful:

For car enthusiasts. Anyone passionate about engines considers his car as a member of the family in all respects. In short, it is not a mere means of transport! He intensively takes care of it, subjecting the car to all possible and unimaginable maintenance and intense cleaning. To take care of your car one hundred percent, all this is not enough. With a diagnostic tool, it is possible to check every little detail, even those not visible to the naked eye.

For those who want to save time and money. Taking your car to the mechanic or electrician means losing a lot of your precious time. A lot of time is needed for diagnostics and obtaining an answer and a quote. By making the diagnosis yourself, you can save some time. The same goes for money. Yes, because the diagnostics from the mechanic or electrician is paid for. Better to avoid spending money unnecessarily when you can buy a highly professional diagnostic tool at a low price.

For those with a rather old car. If your car is about ten years old and has now traveled over 100,000 km, it can very easily run into small problems. Therefore, it is better to constantly and independently check the state of health of the car, find any problems in the bud, and save money and time.
