With technological advances in the automotive industry, it is important to know how to use tools that facilitate troubleshooting in modern vehicles. In this sense, the automotive scanner can be very useful in automotive workshops and centers.

This tool is capable of making a complete reading of the car’s electronics. In this way it facilitates the diagnosis and allows greater agility and precision in the repair.

So, understanding how this device works can facilitate (a lot!) The daily life of any mechanic. Below, we’ll explain everything you need to know about the tool. Read on!

What is a self diagnosis computer?

The automotive scanner is a device used to detect problems in the electronic fuel injection system of cars , as well as information about its repair. This is because it is able to identify the vehicle operating parameters and correct any anomalies in real time.

For this reason, this tool makes the daily life of any mechanic much easier. After all, more and more vehicles have electronic modules that need to be accessed in some way.

To communicate with these modules, the automotive scanner has software that tracks all points in the vehicle. Then a computer code is generated indicating what the problem is. Below we will explain better how this device works!

How does a self diagnosis computer work?

When connected to the car, the automotive scanner receives all system information and fault history. This way you know if the vehicle’s sensors are working properly or if they need to be corrected.

After taking a complete reading of the system and acquiring this information, the device is able to indicate which part needs to be repaired. Some scanners, in addition to reporting the code, inform where the error is and what is happening with the party involved.

Generally, the automotive scanner uses a socket called OBD (On-boarding-diagnostics) or OBD II in newer models. All cars made in Brazil since 2010 leave the factory with this plug installed.

It works as a complement to the car scanner and makes it easier to acquire more accurate information on vehicle operation. When connected, it reads the data and operating parameters of the injection. Then it shows on the display the code of the anomalies that must be corrected in the system.

The scanner, in addition to helping to correct reading errors, can also “reset” the system if necessary. It can also set new electronic injection and ignition advance strategies.

There are also automotive scanner models that establish diagnostics for cars and motorcycles, as well as for trucks, buses and vans.

What problems does the scanner identify?

As seen above, the automotive scanner is capable of taking a full reading of the vehicle’s electronics. Among the main problems that this device is able to analyze are:

  • Fuel consumption
  • air and water temperature
  • battery charger
  • car temperature
  • vehicle rotation
  • Radiator water level
  • Distance traveled

Typically, the biggest problems encountered in vehicles are caused by poor quality fuels . This causes the sensors that have direct contact with the fuel to suffer more.

For this reason, it is common to find oxygen sensors (lambda probe), injection nozzles and spark plugs that indicate a defect in the scanner. Therefore, engine failures and difficulties in starting the car are recurring problems for many drivers.

However, these aren’t the only problems that can arise. Therefore, it is interesting to carry out a complete diagnosis in order to pay attention to all the signals that the car transmits. With this information in hand, it is easier to repair parts that are having problems.

In addition to quick diagnosis, using the automotive scanner also offers other benefits. Check it out!

Prevents further damage

When an injection warning light comes on, it is a sign that there is a problem with the vehicle. With the aid of the automotive scanner it is possible to check where the defect is located more conveniently and precisely. This agility in finding the problem prevents further damage from occurring.

Increases the life of the car

With the help of a scanner, you can quickly and efficiently check which parts of the vehicle need repair. This way the repair can be carried out before other problems appear that affect the operation of the car.

Optimize service times

With an automotive scanner it is possible to evaluate the entire vehicle much faster and more accurately. After all, it already has the error codes that need to be fixed in the system.

In this way it is possible to replace only the defective parts, without the need to replace the parts in good condition. This optimizes service times and even improves productivity during the day.

Typically, the scanner is used when a dashboard light comes on, indicating that something is wrong with the vehicle’s system. However, it can also be used for scheduled vehicle reviews. After all, it will help identify any potential problems.
