How to diagnose my car


Technical diagnostics of a car is a set of goals and tasks related to troubleshooting a vehicle’s mechanisms and systems for their further elimination. Car diagnostics should be carried out by qualified specialists who have at their disposal modern diagnostic equipment. Only this method of diagnosis will allow you to accurately determine the technical condition of the mechanisms, systems and units of the car. To carry out work on diagnosing a car, special sections for diagnosing a car are created.


Every day the type and production of new car models is expanding. Intensive growth of vehicles will cause a further increase in the cost of their maintenance and repair. At present, a number of radical measures are being taken to increase the efficiency of diagnostics, maintenance, and car repairs: the aggregate-precinct method of work is applied; service stations are being created; diagnosis is widely implemented.

Car Engine Diagnostic

Diagnostics of a car engine provides new opportunities for motorists to obtain data on the technical condition of engine systems and mechanisms. Thanks to modern diagnostic technologies.

Technical diagnostics provides significant savings on vehicle maintenance by reducing their downtime during maintenance and repair, performing truly necessary adjustment and repair operations, and reducing the consumption of spare parts and fuel. This is achieved by timely detection and elimination of minor faults in the ignition, power, and transmission units.

The effective use of diagnostic tools at car service stations and motor transport enterprises is possible only as a result of their proper application and operation. Therefore, the study and use of diagnostic equipment, as well as methods for predicting the residual life of a car, has recently been given special attention.
Specialists in technical diagnostics of cars have a crucial task – diagnostics, maintenance and repair of cars with the help of modern diagnostic equipment. The modern computer diagnostics of the car, which is a set of equipment for checking electronic systems of the car for errors and malfunctions, has gained widespread scope.

Computer diagnostics

Computer diagnostics of the car allows you to quickly and accurately determine the malfunction, and evaluate the technical condition of the car (units, components, mechanisms, systems, control units).

The car diagnostic process includes testing all the basic parameters and characteristics of systems that affect the operation of the car (engine control unit, automatic transmission, air suspension, ABS system, security system, cruise control, immobilizer, etc.). Diagnosis of each unit, mechanism and vehicle system consists of several stages, for example:

Engine diagnostics include: Check engine management system; Diagnostics of the fuel system of the engine; Checking cylinder filling, rev analysis, etc.

After the diagnosis, a report is generated that presents all detected errors and malfunctions and proposed methods for their elimination. A specialist in diagnostics offers the best options for repairing or replacing a faulty element, and you just have to make a decision.

It should be noted that the modern complex of car diagnostics allows to find faults in various systems of a modern car, including electronic and even mechanical control systems.

Today, leading car diagnostic companies offer a number of programs for diagnosing a car.

Programs for diagnosing a car are available both in the paid version and in free distribution. Today, programs for diagnosing a car can be found even on the Internet. Computer diagnostics of cars is a step into the future, which helps us quickly identify the problems that arose in a car.

Why do need a car computer diagnostics?

Modern cars have received such an extensive list of functions and tools that you can easily equate it to a robot. For the implementation of the tasks assigned to it, many systems and sensors are responsible for which monitoring should be carried out.

If computer diagnostics were not used on modern cars, one would have to use the old “grandfather way” to look for faults along the chain, which is both long and expensive, given that there are thousands of parts in a modern car.

  1. Exhaust or fuel: A hole in the fuel or exhaust system can allow their telltale odors into the cabin. Regardless of the cause, it’s outright dangerous if you smell either. Car exhaust is rich in carbon monoxide, which can lead to unconsciousness or death if inhaled. If this smell appears in your car, make sure you drive with your windows open so fresh air can circulate through the cabin until you make a permanent fix.

    That’s pretty cool that the computer diagnostics could tell you exactly what is wrong. I feel like that would be much faster than inspecting each part to find out what is the issue. I should make sure that the mechanic I choose to go to is able to do that next time my car has a problem.

  3. My car is Toyota Yaris and I found some noise when driving but not sure about the problem. What kind of diagnostic tool should I use?
