Diagnostic tool refers to handheld diagnostic tool. These automotive diagnostic tools have their own screens, which can display the acquired information, including diagnostic fault codes, freeze frames, real-time data, battery data, vehicle information, I/M preparation data, etc. These automotive diagnostic tools have cables connected to the vehicle. They are plug and play and do not need to connect to external display devices or applications. They are compatible with OBD-II vehicles. Some of these tools can be used in commercial vehicles and passenger cars. Some diagnostic tools have a one-key quick query function, such as VIN, DTC and BAT. The user only needs to press the key on the car diagnostic tool, and the diagnosis starts. Fiberall provides OEM, ODM and R&D services for these automotive diagnostic cables. If you have customized requirements, please feel free to contact us for negotiation.

Introduction to automotive diagnostic tools

①As the name suggests, diagnostic tool (also known as OBD scanner) is a car scanner, which is also a car diagnostic scanner.

②OBD stands for onboard diagnosis. The device is connected to the car via the so-called OBD port and OBD cable (if needed).

③The diagnostic tool stores the data of the access control unit and on-board electronic equipment, and evaluates or analyzes them.

④For this reason, the evaluation from the stored data of the vehicle's electronic equipment is essential for detecting faults.

⑤If necessary, error codes will be generated, but the information provided by the Internet database must be used to analyze these error codes.

⑥Automotive code reader usually only tells you the error code, not the meaning of the error code.

⑦ With the help of some OBDII scanning tools, the error can be eliminated. However, this process is very complicated and requires additional knowledge.

⑧In addition, the diagnostic tool allows reading basic vehicle data, such as fuel consumption, fluid temperature, etc.

Why use automotive diagnostic tool?

Over time, cars have become more modern and digital. In-vehicle electronic equipment is becoming more and more common, and the connection within the car is also closer. As a result, more digital errors may occur, which may affect the condition and value of the car. For example, the airbag may not work properly or there may be a problem with the lighting. Usually we don't even know these errors.

In the worst case, security incidents may also occur. Due to system failures, the service life of the car may be shortened, and maintenance costs are very expensive.

These problems can result in a huge loss of value, which is unacceptable for car owners. Therefore, it is very important to invest in a high-quality automotive diagnostic tool and perform high-quality failure analysis on a regular basis. This can also be done by a trusted mechanic, but it is usually very expensive. However, with a little knowledge, energy investment, and our skills, you can successfully fix most error codes.

Now you know why regular diagnostic testing is so important, it can save a lot of time and money. After installation, the diagnostic device will perform troubleshooting. The OBD-II scanner device is connected to the control unit and ultra-modern in-vehicle electronic equipment, and continuously accepts stored data. This data is largely unimportant and usually remains unchanged. However, certain information is essential to your diagnostic equipment.

When to use the automotive diagnostic tool?

Don't mistake it for the automotive diagnostic tool to be the magic solution for all vehicle failures. It will not repair equipment or replace windshields. If it does, it means that the built-in AI has become too smart. In fact, when the "Check Engine" indicator is turned on, the most basic automotive diagnostic tool will only spit out meaningless code to you. Therefore, if you want to make the most of this tool, you need to know when to use it.

When the "Check Engine" indicator light is on: remember that even if the engine is not disconnected, the indicator light that does not seem to be turned on is still on, which means that many different problems may occur in some parts of the engine, gearbox or exhaust system. If you don't want to ignore it, then the automotive diagnostic tool can come in handy.

When recording vehicle performance/statistics: Some high-end car automotive diagnostic tools can not only read engine codes, but also do more. More advanced tools can perform real-time data measurements on car systems to help you fine-tune settings.

Precautions for using automotive diagnostic tool

If an error occurs in the system or the data does not work properly, the diagnostic equipment will read the error code. Now, all you have to do is determine the source of the problem. To do this, you can browse the Internet or use the vehicle guide. For high-quality diagnostic equipment, sometimes the diagnostic tool will directly display errors.

With this information, you can decide whether to fix the error code yourself or let a professional do the work. The automotive diagnostic tool can usually easily delete what you want to process. But be careful! Possible error codes that are considered harmless are important to the car.

With most OBD automotive diagnostic cables, it will not be possible to create a backup, and the procedure cannot be undone. Therefore, if you are not sure whether you should delete the code, or there is no clear prompt on the Internet, it is best to go to a trusted institution, but you don't have to worry too much about this kind of problem, because they are rare.
