In order for the car to operate smoothly, it is necessary to monitor its technical condition. Using an on-board computer, diagnostics of VAZ 2112 and 2111 with an 8 and 16 valve engine can be done by yourself. The article describes diagnostic devices and provides instructions for its implementation.

Service
VAZ 2110 engines are serviced quite typically. Thus, scheduled maintenance is carried out within 10-15 thousand km. If the vehicle is operated on LPG, then maintenance must be reduced to 8-10 thousand km in order to preserve the engine and extend its service life.
When servicing, it is necessary to pour only high-quality oils into the VAZ 2110 engine. Thus, there are a number of lubricating fluids that must be poured into the engine. Do not forget about using a high-quality oil filter, which will also affect the service life. The power unit maintenance scheme is quite simple, and is provided by AvtoVAZ in the repair manuals.
The VAZ 2110 engine with 16 valves is quite unpretentious in the use of oil. So, both semi-synthetic and synthetic lubricant are ideal for him. Many car enthusiasts ask the question: how much oil should be poured into the engine? Almost all engines require 3.5 liters of oil.

Malfunctions
A major overhaul of a VAZ 2110 engine means restoring the engine and its components to factory standards. This operation is carried out when the motor has passed its service life and there is exhaustion in the main components.
Due to the fact that the engines have been in use for a long time, some engines are 10-15 years old, a major overhaul is inevitable. So, the combustion chambers have already worn out, and the pistons have burned out from service life and mileage. In addition, engine oil for the VAZ 2110 no longer helps to maintain performance to such an extent.
So, it is worth repairing the power unit at a car service center, especially with regard to the 16-valve engine. The VAZ 2110 8-valve engine is used by most motorists in garage conditions, since it has a simple design that is similar to the Classic and Samara power units.

Pinout
If self-diagnosis is carried out, then you need to know the lining of the block. Pinout is the purpose of the contacts that are located on the block. Below is the OBD pinout.
Pinout of OBD II device for VAZ
“A” is the contact responsible for connecting the ground; “B” is the contact that is necessary to connect the L-Line; “M” is a contact that is used to connect K-Line; “G” - contact responsible for controlling the fuel pump; “H” - contact for +12V power supply.
You can diagnose your car yourself by connecting a scanner or other diagnostic equipment to the diagnostic connector. This will save time and money on visiting a car service center.

Connector location and features
For communication with the controller there is a connector, which is a trapezoidal block with 9 blocks. To connect a scanning device, you need to know where the diagnostic connector is located. In a VAZ 2112 car it is located under the instrument panel console to the left of the steering column.
Location of the connector on the VAZ 2112
On the VAZ 2111, the connector is also located in the area of the steering column on the right. Most often it has a vertical location.

Technical specifications
The VAZ 2110 engine has high performance. At the same time, several variants of power units from AvtoVAZ were installed on the vehicle during the production process. The “Ten” had in its arsenal several variants of a sixteen-valve engine.
Let's look at the main technical characteristics of the VAZ engines with which the 16-valve model 2110 was equipped:
VAZ 21120
| Name | Index |
| Volume | 1.5 liter (1499 cm3) |
| Number of cylinders | 4 |
| Number of valves | 16 |
| Fuel | Petrol |
| Injection system | Injector |
| Power | 93 hp |
| Fuel consumption | 7.0 l/100 km |
| Cylinder diameter | 82 mm |
Not a very popular version of the power unit. Although the engine power is high, as practice has shown, this engine did not take root on the VAZ 2110, since it had a number of design flaws. Basically, the engine was installed on a car marked VAZ 21103.
VAZ 21124
| Name | Index |
| Volume | 1.6 liter (1599 cc) |
| Number of cylinders | 4 |
| Number of valves | 16 |
| Fuel | Petrol |
| Injection system | Injector |
| Power | 89.1 hp |
| Fuel consumption | 7.0 l/100 km |
| Cylinder diameter | 82 mm |
A sixteen-valve version of the power unit, which received almost 100 horsepower and had high technical characteristics.
The average lifespan of a Lada engine is 250,000 km. If you use high-quality oil in the VAZ 2110 engine, you can increase the service life of the power unit by 20-30 thousand km.
How can you tell if your car is faulty?
There is a special lamp on the instrument panel with the inscription CHECK ENGINE. When you turn on the ignition, it lights up, and until you start the engine, a special program reads data from all systems and components of the car, thus transmitting data to the on-board computer to identify faults.
After you start the engine, the lamp should go out, but if it stays on for another 10 seconds, it means that some problems have been identified and error codes have been entered into the on-board computer programs. Communication with the controller is carried out using the diagnostic block.
