How and why is computer diagnostics of cars?

Not long ago, the diagnosis of the vehicle using a computer seemed to be something fantastic. In today's world, if you have a large number of software and hardware, this procedure has become more accessible to a wide range of motorists. To conduct computer diagnostics of the car with your hands do not need expensive equipment and technology.

Why do we need diagnostics?

Check parts of the vehicle using the electronic device helps to know their status without an analysis and thorough study of breakage. This is accomplished by use of special electronic systems and receiving data from them. However, not all models are equipped with this equipment and cannot be scanned with the help of software tools.

How to conduct computer diagnostics of the car?

Many models auto release after 2005 are equipped with a special connector that receives special signals about the status of devices and nodes. It is located in most cases near the steering column or on the console. Before performing the self diagnostics should refer to the user manual.

Earlier models can be equipped with a connector, which is located under the hood. In this case, it is likely not universal and will have to find an adapter for a specific model.

Connectivity

To conduct computer diagnostics of the car today, there are two main approaches — using your PC and smartphone or tablet. In the first and in the second case, you will need to use the specific software. In addition, you will need a device that can read the errors, supplied the vehicle's electronic systems. One of the most popular and compact of them is an ELM327.

Diagnostics ELM327 example

The scan tool ELM327 connects to the car through OBD2 connector. It is universal, can read codes with different models of appliances and connects to a personal computer and to mobile phones based on "Android".

For ELM327 is a large range of software to conduct computer diagnostics of cars. Available software and for Windows and for Android. Moreover, there are both paid and free equivalents.

Description of the process step by step

First is to detect the location of the OBD2 connector, if equipped. Then you want to insert the ELM327. It is worth noting that this scanner can be supplied in several different versions — Bluetooth, Wi-Fi or cable. Depending on the type and selected software to conduct computer diagnostics of the car.

The Most famous program — Torque for Android. It shows errors, the overall condition of the car and other current parameters such as the temperature of the nodes, the engine speed, its power, etc.

In this program of computer diagnostics of the car are interested in the ability to display error codes. That is what determines the fault, which was later to be repaired.

It is Worth noting what kinds of errors there are two — ever or current. The diagnosis applies to the second type.

There are different versions for the Windows environment. For example, copes with its task ScanMaster-ELM. Has a great set of settings and options. You can set a profile for your specific car, if you intend to scan on other models or brands.

The program can display information about the car such as VIN, a variety of readings from sensors, temperature, speed and many other useful information. Has a user friendly interface, easy to “iron” of a computer. For versions of the ELM327 Bluetooth will need the same technology on the PC.

After issuing error codes is used a special table, which is initialized according to one or the other fault. It is quite extensive, but it is easy to find online for free access. Each code describes a particular type of node and an individual fault.

It is Worth saying that this diagnosis does not give 100% result. It only allows to identify the most probable locations of the fault.

Consequences

After a successful diagnose and repair the error, you need to remove. This can make many programs, including the above-mentioned Torque. Why is it necessary? This will enable the avoidance of doubt the subsequent diagnosis.

In conclusion

Equipment for computer diagnostics of the car in our time can be purchased by anyone. And most of it half probably already have. This is a laptop or tablet. It remains to find a suitable scanner or the adapter and download the software.

Still, conduct computer diagnostics in the home is an extreme measure. It is better to turn to professionals. Without skills in technology and the understanding of the electronic control units of the vehicle to reliably establish what happened to the car, will be problematic.
