Step-by-step instructions for diagnosing a VAZ-2110 with your own hands

To carry out computer diagnostics of a VAZ-2110 car, it is recommended to contact specialized car services that have all the necessary equipment at their disposal. However, this approach has several significant drawbacks. Firstly, the procedure for identifying faults in a service station can be quite expensive. Secondly, unscrupulous technicians have a bad habit of embellishing the results obtained and claiming faults that actually do not exist.

That is why in this article we will look at how to do computer diagnostics of a VAZ-2110 with your own hands, provide detailed step-by-step instructions and help you minimize costs.

What is needed to diagnose a VAZ-2110

So, to check your car for faults, identify injector failures and on-board computer errors, you will need the following:

• an adapter designed to connect the ECU (electronic control unit of a car) with a PC, as well as display all the results obtained on the display of a tablet, smartphone or laptop. When purchasing an adapter, you should definitely take into account all the features of the car, since these devices are not universal. For VAZ-2110 cars, the ELM327 model would be an excellent choice;
• a cable that allows the adapter to be connected to a personal computer and the vehicle’s diagnostic connector. Its length should be no more than 5 meters, so be sure to take this requirement into account when choosing equipment for diagnostics;
• laptop or tablet. Many experts strongly recommend using a portable laptop computer, which will provide you with complete freedom of action in the process of carrying out diagnostic work;
• software. Its most current version can be easily found on the website of the adapter manufacturer or on specialized websites dedicated to the diagnosis and repair of the VAZ-2110.

What is the difference between VAG adapters? Beware of fakes!

The main difference that can affect the price and functionality is the chip on which the adapter is made. Cheap adapter models use a chip with limited functionality - as a result, it may not read some car blocks. Our adapter is made on the original FTDI chip. Today it is considered the most functional - it reads 100% of the car blocks supported by the adapter. In addition, it has support for flashing many Russian models.

Beware of fakes! Diagnost7 is the only company in Russia that officially supplies adapters based on the original FTDI chip.

All drivers, programs and detailed instructions are included with the adapter. Place your order today and receive them!

The adapter includes more than 30 programs for different brands of cars. Here are examples of the programs that come with the kit:

This adapter can diagnose VAZ, GAZ, UAZ, ZAZ with an ANDROID phone and tablet

After the diagnostics charged 800 rubles for removing errors, I ordered an adapter. The kit included an adapter for ZAZ CHANCE (Sense) and an adapter for the phone (though for a micro USB, bought for 100 rubles on Taepsi). I installed the program and did not connect!! )) In the settings you need to specify the make of the car and immediately identified the errors. I threw it away, played around with it, and was satisfied, my friends told me. I didn’t order from Alika, there is no support there and the guys immediately answered all the questions by email.

Verdict: Everything is honest, it works, it eliminates errors, I recommend it, it fits most cars!

Features of computer diagnostics of a car

How is diagnostics carried out using all the equipment and software listed above? A detailed description of this procedure will help you answer this question:

• diagnostic software transmits a request to the car controller via the adapter;
• the controller, in turn, provides all the necessary information about the state of the main on-board systems of your car;
• the software analyzes the data and displays the result in the most readable form;
• Using information on the Internet, you decipher error codes obtained as a result of diagnostics and identify problems with certain components and mechanisms of the car.

Data is transferred to the computer via the ODB II protocol. It has a number of disadvantages, but the VAZ-2110 is quite suitable for diagnosing a car, since domestic cars are equipped with significantly less electronic equipment than modern imported equipment.

ELM327

Separately, we will introduce you to the ELM327 adapter, with the help of which many VAZ 2110 owners perform full diagnostics on their own.

ELM327 is one of the latest OBD developments. This scanner is used to check cars using a computer. The key advantage is that the device supports all known OBD protocols and interacts with many diagnostic programs. A USB cable is used to connect the device to a computer.

ELM327

The software for the ELM327 is mostly free, although some software is available only for a fee.

The adapter can work on computers with different OS. Namely:

• DOS;
• Windows;
• MacOS;
• Linux;
• PalmOS;

The full capabilities of the scanner can only be fully realized through properly selected software. For self-diagnosis, software for scanning the transmission and engine is available free of charge. Commercial versions of the programs allow you to additionally check other components of the car.

Key Features

Let's take a look at the capabilities that the ELM327 chip provides:

• Reads error codes and vehicle malfunctions;
• Displays codes and their descriptions;
• Exports data for printing, if necessary;
• Removes error codes;
• Displays data in metric and US measurement systems;
• Records, saves data, builds graphs;
• It has an acceleration counter from 0 to 100 km/h, which allows diagnostics on the go.

Many vehicle operating parameters must be checked while driving. Not all adapters are suitable for this, so it is important to choose equipment that suits your requirements.

Main types of computer diagnostics

The adapter, which is connected to the on-board computer system and your laptop (or tablet), allows you to carry out the following types of diagnostic work:

• assessment of the technical condition of the engine. It will allow you to find out why the power unit suddenly loses its original power, and will also help you understand why fuel consumption increases and problems arise with starting the engine;
• suspension diagnostics, which is simply necessary if problems arise with the maneuverability of the car, tires wear unevenly, or extraneous sounds appear while driving;
• checking the condition of the automatic transmission. You will not need this function, since the VAZ-2110 is equipped with “mechanics”. However, it is of great importance for diagnosing other machines.

Idling

Code 0505 indicates a malfunction of the idle air control. Moreover, 0505 is most often “issued” when the engine is started with the gas pedal pressed. This often affects drivers who switched from a carburetor VAZ 2110 to an injection one.

However, 0505 also occurs if the ignition module, spark plugs are faulty, there are broken wires, or the engine speed is not the one set by the XX regulator.

Idle speed control

If you notice popping noises in the muffler, this may also indicate displacement of the crankshaft ring gear. Code 0505 can be displayed either alone or with 0300 (missing cylinders).

How to independently diagnose a VAZ-2110

The last question that remains to be addressed in our article is the sequence of diagnostics of the VAZ-2110. It looks like this:

• connect the adapter to the ODB diagnostic connector, which is located under the steering column;
• turn on the tablet or laptop, on the screen of which the diagnostic results will be displayed;
• turn on the car ignition. To check the engine and suspension, as well as to display the necessary information on the display, a mandatory power supply to the on-board network of the machine is required;
• launch the software and get the results of diagnostic procedures;
• We decipher error codes and determine malfunctions of certain components and mechanisms of the car.

Other combinations

The errors described above are not the only ones. And in practice you can find a large number of different codes:

• P0101-P0103
  these codes are associated with the fuel consumption sensor. Most often the device needs to be replaced;
• P0116-P0118
  - . There may be a problem with the wiring, so it is advisable to first check the power circuit to the sensor;
• P0112-P0113
  This code occurs when the sensor indicating the intake air temperature is faulty. Often occurs when there is a short circuit in the wiring;
• A number of errors (P2122, P2138, P0222, P2123, P0223) indicate problems with accelerator position control;
• P0130-P0134
  - the oxygen level sensor in the mixture should be replaced. Before doing this, check the condition of the wiring supplying power to this sensor;
• P0201-P0204
  - problems with injectors. Possible blockage or short circuit. Be sure to check the wires supplying power to them;
• P0136-P0140
  , such codes indicate a malfunction in the sensors that control the formation of the mixture in the injection system;
• P0326-P0328
  - failure of the detonation detecting device. Occasionally may appear when the engine control unit fails;
• P0351-P0352, P2301, P2304 all these readings indicate incorrect operation of the ignition coils; usually with these errors the engine stalls;
• P0691-P0692
  - failure of the first fan relay operating in the cooling system;
• P0485
  - erroneous voltage signal coming from the cooling fan;
• P0693-P0694
  , the second relay of the cooling system has failed. With such a breakdown, the antifreeze may boil and the engine overheats. To avoid a more complex breakdown, you need to fix the problem;
• P0422
  The converter has failed; the unit needs to be replaced;
• P0560-P0563
  - faulty voltage in the on-board network, the condition of the battery is checked;
• P0627-P0629
  - erroneous signal from the fuel pump sensor. If the engine starts, then the problem is in the sensor. A malfunction of the fuel pump itself makes it impossible to start the engine.

These are the most basic error codes. More detailed information can be found in the file that usually comes with the diagnostic program. All identified defects must be repaired. After which the errors are reset and a recheck is performed. Reset errors

. To reset the controller readings, disconnect it from the power supply. To do this, you need to turn off the engine by turning off the ignition. After which the positive terminal is removed from the battery, after 10-15 seconds it is put back in place. All errors have been cleared. You can start the engine and carry out control diagnostics.

Installing a new adapter

Modern adapters elm 327 with the OBD-II program (puncture) are suitable for the VAZ 2110 . You can also install them yourself. First you need to purchase an elm 327 and a cable for it. You already know the location of the diagnostic connector. Be sure to study the instructions, which indicate the pinout of the block and the location of each connector.

Scan Tool Pro Scanner

Do not try to buy cheap Chinese adapters that Aliexpress offers. There is a huge chance that it will not work at all. Take it where there is a guarantee and the seller is responsible for his product.

The original Scan Tool Pro or Smart Scan Tool Pro device must have a microcontroller from Canadian manufacturers; what is sold in Russia and the CIS countries is mainly China. The Korean assembly works great (links to them in the text). The majority of devices have a cheaper version of the microcontroller and various firmware, and accordingly their cost is low. But I don't want to say that they won't work. They work quite well. You just have to choose the device that will work on your car, or maybe not.

Top part

So let's start from left to right. First, the top part of the control panel:

1. Side scale from 50 to 130 and arrow. Shows the temperature of antifreeze (antifreeze) in the engine cooling system;
2. Almost round scale (0 – 80) and arrow. Tachometer showing engine speed;
3. Two arrows at the top, almost in the middle of the control panel - turn signals (right, left);
4. Speedometer. Well, this device, probably everyone knows, shows the speed at which the car is moving;
5. A side scale with an arrow and, most often, two images of a filling column (white and red). Instead of a red column there may be a yellow light. This is an indicator of the fuel level in the tank. If the red column (yellow light) lights up, it means that there is very little fuel left in the tank - no more than 7 liters, urgent refueling is required.
