Diagnostic equipment for car

Today it is difficult to imagine a car service that does not use diagnostic equipment for a car in its activities. All modern cars are equipped with an electronic engine control unit, with the help of which all processes occurring in the engine are coordinated.

The electronic control unit (hereinafter referred to as the ECU) for the engine reads the readings of all sensors and, depending on the readings, adjusts the fuel-air mixture. For example, when starting a cold engine, the mixture must be rich in order to ensure good combustion.

Case study: The vehicle's coolant temperature sensor is out of order. when the ignition was turned on, the sensor readings jumped to 120 degrees, then 10, 40, 80, 105, etc. and this is all on a cold engine. Accordingly, he gave incorrect readings in the ECU, which caused the car to start badly, and if it did start, then with jumping revolutions, dropping to 200 rpm, and there was absolutely no reaction to the gas pedal.

When the sensor was disconnected, the car started and ran smoothly, but at the same time, since there was no temperature reading, the radiator fan immediately turned on. After replacing the sensor, everything began to work smoothly. How the coolant sensor changed, read in the article - replacing the coolant temperature sensor.

Diagnostic equipment allows you to identify vehicle problems without having to disassemble it. As the practice of modern car services shows, it is possible to replace half of the sensors by typing before finding a problem or not finding it at all.

How to choose diagnostic equipment for a car

In order to understand how to choose diagnostic equipment, you need to answer the following questions:

• what brands you will diagnose (if you plan to service different cars within the framework of a car service, then multi-brand diagnostic equipment is perfect, and if the work will take place on one brand of car, then you can purchase official dealer equipment);
• a set of necessary functions (depending on the direction of your activity);
• the presence of a Russified version (an important factor in the absence of knowledge of the English language).
