What problems does the VXDIAG VCX NANO PRO identify?


With the technological advances in the automobile sector, it is important to know how to use VXDIAG VCX NANO PRO tools that facilitate the resolution of problems in modern vehicles. In this sense, the automotive scanner can be very useful in workshops and automotive centers.

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

Therefore, 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 VXDIAG VCX NANO PRO. Read on!

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

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

To communicate with VXDIAG VCX NANO PRO modules, the automotive scanner has software that tracks all points on the vehicle. Then a computer code is generated that indicates what the problem is. Below, we'll explain better about how this device works!

How does an automotive scanner work?

Thus, it is possible to know if the vehicle's sensors are working correctly or if they need to be corrected.

After performing a complete reading of the system and acquiring this information, the device is able to inform which part must be repaired. Some scanners, in addition to pointing out the code, inform where the error is and what is happening with the part involved.

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

Is it easy to use VXDIAG VCX NANO PRO?

VXDIAG VCX NANO PRO works as a complement to the car scanner and makes it easier to capture more accurate information about the vehicle's operation. When connected, it reads data and operating parameters of the injection. It then shows on the display the code of faults that must be corrected in the system.


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

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

What problems does the VXDIAG VCX NANO PRO identify?

As seen earlier, the automotive scanner is capable of taking a complete read of the vehicle's electronics. Among the main problems that this device is capable of analyzing are:

  • Fuel consumption
  • air and water temperature
  • battery charge
  • car temperature
  • vehicle rotation
  • Radiator water level
  • Travelled distance

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

For this reason, it is common to find oxygen sensors (lambda probe), injection nozzles and spark plugs pointing to a defect in the scanner. Therefore, engine failure and difficulty in starting the car are recurrent problems for many drivers.

How does VXDIAG VCX NANO PRO transfer data?

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

In addition to quick diagnosis, using the VXDIAG VCX NANO PRO also offers other benefits. Check it out!  

Prevents further damage

When an injection light comes on, it is a sign that there is a problem with the vehicle. With the help of the automotive scanner it is possible to verify where the defect is with more practicality and precision. This agility in the search for the problem prevents further damage from happening.


Increases the life of the car

With the aid of a scanner, it is possible to quickly and efficiently check which parts of the vehicle need repair. Thus, it is possible to carry out the repair before other problems appear and affect the car's functioning.

Optimizes service time

With an automotive scanner it is possible to assess the entire vehicle much more quickly and accurately. After all, it already has the fault codes that must be fixed in the system.

This way, you can only replace the parts that are defective, without the need to exchange parts that are in good condition. This optimizes service time and even improves throughput throughout the day.

Typically, the VXDIAG VCX NANO PRO is good 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 overhauls. After all, it will help to identify any potential problems.

What is the best automotive scanner?

Because it offers more practicality and precision, the automotive scanner is a very useful tool for everyday life in the mechanic shop. Therefore, it is valid to invest in this type of device to optimize services.

Nowadays it is possible to find several scanner models both from national and imported brands. In addition, the main manufacturers in the market offer a very wide coverage of the national fleet.

Regarding models, there are many available to meet your needs. Some are even able to diagnose cars and motorcycles, as well as vans, pick-ups, trucks and buses.

By the way, some more modern models of automotive scanner already have bluetooth technology integrated in their systems.


Therefore, when choosing, choose the device that meets the main demands of your workshop and fits the profile of your customers. Also, check if the manufacturers offer training to mechanics on how to use the device, as well as a warranty of at least one year.

Snap-on VXDIAG VCX NANO PRO is good for courses in automotive mechanics. The device is designed to meet the day-to-day needs of a workshop. For this, it allows performing all types of diagnosis in cars, light commercial vehicles, motorcycles, among others.
