What can be checked using autodiagnostics

The main tasks of automotive analysis are to detect and obtain the error code. You can obtain information about the presence of a breakdown after comparing the factory parameters with the data that was obtained during car diagnostics. Manufacturers enter information into ECU databases for further reading.

If the real values ​​diverge from the specified parameters, an error occurs in the form of a code. Thanks to autodiagnostics, you can check any parameters in the engine.

To check the electronic control unit using a computer or laptop, you need certain equipment. The main components used in diagnosis are:

• Scanner;
• Software;
• Adapters;
• Personal computer or laptop.

Information is received from the ECU using an adapter. It performs the following functions:

• Reading the problem code;
• Troubleshooting;
• Connection to a laptop with installed software;
• View engine parameters in real time.

There are 3 types of adapters that are used to perform different tasks. These include:

1. Amateur. Scanners of this type are used by ordinary car enthusiasts who carry out auto diagnostics on their own. The devices are based on the ELM 327 microprocessor. They independently eliminate errors when the Check Engine lights up.
2. Multi-brand. They are universal because they can be used to diagnose different brands of cars. The adapters detect common DTCs, indicate the location of the breakdown, and also provide recommendations for correction. These devices are designed to work with PCs or smartphones.
3. Dealerships. Similar equipment is installed in dealership car centers. It is also purchased for a specific car model. These adapters are quite expensive, but their advantage is the ability to diagnose trucks.

The most popular among car enthusiasts are amateur adapters based on the ELM 327 processor. In addition to the main functionality, they are capable of:

• Read and reset the AntiLock brake system, airbags and ABS;
• Determine the VIN parameters of a car, obtain data about the engine and gearbox;
• Scan sensors in motion at a time convenient for the car owner;
• Update online thanks to technical support;
• Save the necessary data for further use;

How it works?

The OBD system is a separate type of diagnostics using computer technology. This is one of the mandatory international requirements introduced in 1991 to control emissions. A few years later, the second generation of the OBD-II system was introduced. It entailed the establishment of standards for communication protocols in ECUs for car manufacturers.

OBD ports are often located near steering columns. They are used to connect electronic devices for the purpose of analyzing data from an on-board computer. In addition to basic information, many car manufacturers have data for specific models. To obtain the required parameters, use a profile scanner.

The engine control system consists of many components: relays, sensors, as well as a number of other systems and mechanisms. They are designed for the normal operation of electronic control units that perform several tasks:

• Counting air flows and transmitting the necessary information to the device;
• Correcting information based on the received data, processing it and making changes to the database;
• Control of various engine parameters;
• Adjusting the position of the throttle valves.

Characteristics in the rating

A modern car is controlled by a computer, and to configure and diagnose it, it is sometimes necessary to contact specialists at service centers. However, you can do this kind of work yourself - just install a special program (there is software for different OSes, including Android) and connect to the car's ECU via the OBD2 interface.

Our review is dedicated to the best software for analyzing and tuning engine computer systems. Both paid programs and freely distributed software take part in the rating. The product evaluation is based on the opinions of car diagnostic specialists, as well as owners who perform this procedure on their own.

Car diagnostics via laptop

Before you learn how to diagnose a car engine yourself, you need to know in what cases to carry out such work, what it reveals, and learn to read error codes. Modern advanced version programs for car repair shops provide information on even minor deviations from the optimal operation of the car’s engine. In addition to diagnosing the internal combustion engine, computer diagnostics via a laptop also shows what malfunctions exist in the transmission system and chassis of a complex vehicle design. You can quickly learn to do such work yourself.

Basically, computer diagnostics begin to be done to configure the control unit (CU). After identifying the causes of unstable operation of the internal combustion engine, you must be able to correct these malfunctions. Error detection alone is not enough.

A newbie to car diagnostics can do the following:

• reduce and increase idle speed (idl);
• adjust the fuel supply or, scientifically, adjust the lambda characteristics;
• if the program is an extended version, with additional plugins installed (something that expands the functionality), then you can program the car electronics interface;
• adjust auto-check in case of existing malfunctions or observed deviations in operation.

Scanner selection

The scanner can be completely different. There are professional ones who work with the entire car, and there are those that are designed to read information only based on certain indicators. Also, not everyone is universal and is not able to work with a huge number of manufacturers. This must be taken into account when purchasing.

Multibrand adapters work with almost all machines. They are popular due to their cost and quality. The same Smart Scan Tool scanner is quite common and known among all drivers. It is adapted for all cars that are no more than 20 years old at the time of the version update. The full version can be purchased for $30 and you can already monitor all problems. Next, let's look at the programs.

Useful tips

The length of the data cable is of great importance. Its size should be as small as possible. The longer it is, the more inaccurate the scanner is. It should be noted that with a length of 5 meters, the device does not work at all.

Before using the scanner, you need to read the instructions for it in order to know all the nuances of working with the device. During diagnostics, it is necessary to check the condition of the scanner and laptop. The ignition must be turned off, otherwise the on-board computer may be damaged.

Necessary equipment for engine diagnostics

To successfully diagnose a car via a laptop, you need to comply with some requirements. There are many testing devices today. Specialized software is produced for each make and model of car. Although, there are software and adapters that are suitable for various brands of cars.

First of all, the driver needs to find the place where the diagnostic device (scanner) is connected. This could be under the glove compartment, near the steering wheel, etc. Today you can buy a scanner inexpensively. The scanner connects to the control unit through a connector and reads various combinations of errors. The scanner makes it possible to obtain complete information from sensors and vehicle control systems. The scanning device will analyze the performance of all critical components of the car structure.

Before purchasing a scanner, be sure to make sure that it fits the required make and model of car. Of course, it will not show the oil level in the engine and in the box, and will not check the ball joint, but it will provide information on many other parameters.

If you don't have a scanner

If there is no scanner for car diagnostics, then you can carry out troubleshooting work without it. For this you need:

1. Laptop or computer.

2. Adapter. It connects to the diagnostic connector. Also purchased depending on the make and model of the car. One of the most common adapters is the K-Line adapter. It is suitable for many makes and models of passenger vehicles. The adapter comes with a cord for connecting the connector of the machine and laptop, and a CD with software.

3. Software. There are also many diagnostic programs, as well as devices. There are universal programs with which you can do do-it-yourself diagnostics of cars of different brands (domestic and imported). There are programs only for a specific machine.

Software for car diagnostic devices

Wifi and bluetooth devices

The advantages of working with such adapters are the ability to synchronize with the car wirelessly. Convenient to diagnose while driving.

Working with such wireless devices is not difficult:

1. Insert into the connector in the car to connect the scanner.
2. Turn on Wi-Fi or Bluetooth on the device you want to connect (laptop, tablet, phone).
3. After connecting the car and the device, run the diagnostic program.

One of the most common scanner-adapters is the ELM 327 scanner. It can also be easily ordered from Aliexpress. The main thing is, before purchasing, look at the list of which cars they can diagnose.

Devices running the Android operating system (Android

For devices with the Android operating system, you will need to install applications for car diagnostics. According to reviews and comments, the Torque Pro application is installed the most. Reviews often say that this application provides accurate data.

Torque Pro functionality:

• the parameters of the scanned vehicle are immediately visible on the screen;
• diagnostics occurs completely;
• The GPS track allows you to record actions, which is very convenient (allows you to see what was scanned before).

The program interface is clear and convenient even for a beginner.

Devices running the Windows Mobile (Windows Mobile) or Java operating system (Java)

For tablets and phones with Windows and Java operating systems, the most recommended application is Check-Engine.

This application not only reads the errors found, but also deciphers these error codes.

After correcting the errors, the Check Engine utility will erase old errors from the control unit’s memory. To save and generate a report, the application shows tips on how to make a report and send an SMS to a specialist.

The most common error codes

They consist of 5 characters . Each brand of car has its own, the most common of them are associated with damage to the electrical circuit, disturbances in the removal of exhaust gases, failure of the sensors themselves, problems with voltage in the on-board network or with the speed of the car.

If previously a car was repaired “at random”, relying only on the skill of a car mechanic at a service station and the uncharacteristic sound of the car, now almost any car enthusiast, if desired and with the necessary equipment, can diagnose his car himself, identify the car’s fault with his own hands and fix it. You can also entrust this to professionals.

Fault diagnosis by electronic testing

The scanner is connected to the internal vehicle BSA via a special connector. The device or equipment has complex firmware, which must be updated to the latest version. Diagnostics has a number of autonomous operations.

Suspension

The chassis check is carried out after the owner of the car detects obvious signs of malfunction - skidding of the front or rear axle, as well as uneven tire wear or knocking noise during normal movement and maneuvers. Another characteristic symptom of a problem with the suspension is false activation of the ABS and an increase in steering play. Also, CD is carried out after detecting icons on the instrument panel that diagnose problems.

Computer diagnostics of suspension

Read more about signs when you need to test your suspension:

• There is a knocking sound when turning;
• tire tread wears unevenly;
• the noise increases off-road;
• at speed the car skids to the left or right;
• shaking is felt when moving;
• The anti-lock braking system does not work at the right time.

Before computer diagnostics, the car's chassis is checked by hand. If there are large gaps between parts, the CD procedure must be carried out without fail.

Power unit

Computer diagnostics of the internal combustion engine is mandatory in cases where the car owner notices prolonged heating of the unit, an increase in fuel consumption, and loss of power.

You need to urgently examine the engine if it is difficult to start or smoke of an unnatural color is coming out of the exhaust system.

During the electronic test, compression is also measured.

The appearance of the “Check” icon on the dashboard always worries the caring car owner. Without special equipment, it is extremely difficult to find out the reason for the unstable behavior of a modern car engine. The most common situations when urgent testing of a power unit is required:

• warning icons on the panel - the indicator lights up when one of 200 error codes related to engine operation is detected;
• increased fuel consumption - if the air filter, air flow sensor, lambda probe and various elements of the fuel system are damaged, gasoline or diesel fuel burns at a high speed.

The principle of CD of gasoline and diesel engines comes down to deciphering special codes showing the state of electronic systems. They are displayed on the device display in the form of certain symbols.

Engine diagnostics using a special device

A specialist must be able to decipher data, generate a report describing specific faults, and find effective solutions to radically correct the performance of the internal combustion engine.

Automatic transmission

The reason for testing an automatic transmission is the following characteristic symptoms: the transmission starts jerkily, makes noise, slips and is unable to work normally. Fuel and oil consumption also increases. The CD reads errors in the automatic control unit and also displays readings from sensors and regulators.

Checking the automatic transmission is also necessary in the following cases:

• after the malfunction indicator lights up on the instrument panel;
• before buying a car from the secondary market;
• once a year for prevention.

The automatic transmission must be electronically inspected regularly in order to identify problems in time. This will avoid serious damage and expensive repairs.

If the car has a high mileage, then it is imperative to diagnose the automatic transmission. This also applies to operating conditions. For example, if the car is equipped with a tow bar and is subject to additional loads, the service life of the automatic transmission is noticeably reduced.

Computer testing will allow you to avoid unnecessary oil changes, valve body flushing or solenoid cleaning. Usually these services are offered by unscrupulous employees of left-wing services, trying to make money. It all starts with the client's complaints about shocks when braking when switching from third to first gear. If you carry out proper diagnostics, the scanner will instantly show that the firmware of the electronic unit is outdated and the machine needs to be reconfigured. After installing fresh software, the tremors disappear.

Diagnostic parameters for VAZ injection engines

What to pay attention to:

1. With the engine turned off, temperature sensors (data correctness); - throttle valve (presence of wear of the throttle mechanism; maximum wear - no more than 2%); — oxygen sensor (ADC MAF); presence of channel wear; maximum wear - no more than 1,035 V;
2. With the engine running and warmed up to normal (idling speed), the following parameters are checked (the value in each specific case depends on the engine model and ECU): - revolutions per minute; — air consumption for an 8 valve engine; — air consumption for a 16 valve engine; — injection time; if necessary, injection correction; — correction factor (%); — multiplicative component of correction; — additive component of correction; — cyclic air consumption (mg/stroke) for an 8-valve engine and for a 16-valve engine.
