7 Tips to Solve vxdiag gds2 Common Issues


What is automotive diagnostics?

 vxdiag gds2

vxdiag gds2is an analytical process for finding the cause of a car problem. From the idea that the image suggests, we have a process to be followed.

First, we receive the symptom. It is usually the reason that makes the customer look for the workshop. Therefore, the consultative interview is very important. You can find key details to advance the process.

Once the symptom has been identified, we must troubleshoot. That is, what is generating such a symptom? From this, we define the cause: which, fatally, is the origin of our failure.

Why do we need vxdiag gds2?

Do you realize the importance of having a process, that is, a sequence of procedures in vehicle diagnosis? Now, that old professor's phrase makes a lot more sense.

We kill the problem on paper. We don't go out disassembling the vehicle anyway. This is the last step. Dismantling the vehicle left and right wastes your time and takes unnecessary risks.

See the explanation of the technical consultant of our company, about each of the stages of the vxdiag gds2process.


It is the manifestation of failure that can be seen, heard, felt or measured.

View: dashboard lights, oil leak, engine smoke, among others.

Heard: noises in the bearing, motor, and belt, among others

Direction: temperature, car crashing, air conditioning not working, among others.

Measurements: to measure a symptom it is necessary to use an automotive diagnostic device such as a multimeter, scanner and oscilloscope.

Failure in vxdiag gds2

Automotive repair failure is an anomaly present in a component or system that impairs its perfect functioning. In other words it is the defect present in the car. We can detect it via vxdiag gds2.

Let's say that the vehicle that doesn't start because it doesn't have a signal on the rotation sensor. The problem could be with the rotation sensor itself, but it could also be the harness or the module that is not feeding.

So here we have the symptom and the failure, understanding these two is fundamental for the final step: the cause.


The cause of a car defect is the reason, the reason, and the origin why the failure occurred.

Let's look at an example. In the diagnostic process the customer is complaining that the injection light is on.

How to connect vxdiag gds2 with vehicle?

When connecting the vxdiag gds2, which is combustion failure in cylinder 1. This could be nozzle, ignition or understanding. During the process, after talking to the customer, it was discovered that the defect is in the nozzle, that is, the cause of the problem is the nozzle.

Therefore, the consultative conversation with the client is essential. They should be open-ended questions that instead of “yes or “no” the customer talks about what is happening so that you retain as much information as possible.

Then, in the consultative conversation with the client, you discover the symptoms. Afterwards, it observes the faults and based on them, it uses the scanner to discover the cause. But the vxdiag gds2will not bring an exact result, but an approximate one, so we compare the scanner result with the customer's responses and failures.

Prerequisites for Automotive Diagnosis

What are the prerequisites for a good automotive diagnosis?

Repairman: is the professional who has knowledge about the vehicle's mechanical and electronic system.

Tools: scanner, multimeter, oscilloscope and technical literature, which will give support and support in carrying out the tests. To stay on top of the main equipment for repairmen, visit our content: Special vxdiag gds2 tools.

Strategies: it is the map, the path to be followed until the cause of the anomaly.

From the moment the repairman discovers the defect through the tools, it is time to devise a strategy to do the job quickly and to the point.

Steps for an agile and efficient diagnosis

 Conversation with the customer:  The owner arrives at the workshop and complains that the vehicle is failing. Ask questions about the car's symptoms, as the more information you get about the defect, the better and faster the diagnosis will be made.

To map and direct the repair, check out some initial questions: in which usage situation does the car fail? Does it happen with a cold or hot engine? When the car engine was last serviced?

  1. Problem detection:  to facilitate diagnosis, many repairmen use the vehicle. When driving, they simulate any fault conditions or claimed defects. After this verification, it is possible to have a base of which system is causing the anomaly (power system, ignition, electronic injection, engine, synchronism, among others).
  2. Preparation of material:it is time to organize the equipment and technical material necessary for the diagnosis and repair of the vehicle. Electrical schematics, maintenance manuals and technical information (which are related to the analyzed systems) are important.

Among the equipment, in addition to the oscilloscope, scanner and automotive multimeter, have the polarity pen at hand; the compression pressure gauge; the vacuum pump; the gas analyzer, among others.

 Defect Code Interpretation vxdiag gds2

If using the vxdiag gds2, you must read defect codes on the electronic injection system. Write down the codes found and, after that, carry out the component-specific tests for the code that appears on the display, check its operation and find the defect.


 After verifying the problem, you can carry out the correction, maintenance or replacement of the component, as necessary in each case. Afterwards, use the automotive diagnostic device and check the reading of the fault codes again. If the anomaly is resolved, no more codes will occur and the engine will run flawlessly.

 Test the vehicle:

Riding the vehicle one more time serves as the final test. When delivering the service to the customer, ask him to drive and find the solution to the defect he was complaining about. Explain which and why of a particular failure, which maintenance has been carried out and show the components replaced.


In addition to informing you of everything that was done to solve the problem, this final conversation demonstrates reliability and good service. It is definitely a positive thing for the customer, making them look for your service again.
