Additional functions
The display also displays other parameters of the Lada Vesta, which greatly facilitate driving not only for beginners, but also for experienced drivers. For example, data from parking sensors ensures easy parking of a car by generating light and sound signals. On-board computers are provided on the entire Lada vesta sw cross line, station wagons and other luxury models. The operation of standard electronic devices is ideally complemented by additional equipment; its installation is carried out at service stations or with your own hands. For example, the standard cruise control of the Lada Vesta successfully interacts with the additional onboard onboarder. Modern onboarder models have advanced functions: they are integrated with a satellite navigation system, equipped with an Internet connection and TV.

Where is the LADA VESTA ECU located?
The ECU on the Vesta is located in the engine compartment (engine compartment). The control housing is rigidly fixed to the vehicle frame. The wiring harness approaches the device from below and is connected through a block with latches. Due to its location under the hood, the VESTA ECU can become a target for thieves who replace the device with another. The method of protecting the unit from intruders is an additional housing made of 3 mm steel with stud fastening to the frame.
The connection between the ECU and the CBKE, which is located under the dashboard to the right of the driver, in the Lada Vesta is made through a connector with 16 contacts - OBD2. The block is located in the cabin to the left of the driver's seat under the panel, near the hood lock handle. The OBD2 contact connector is an open type.

Are you satisfied with the functions of the Lada Vesta on-board computer? Let us remind you that other operating instructions for this vehicle can be found in this section.
It is difficult to imagine a modern car without an on-board computer (alternative names: “BC”, “carputer”, “onborder”), which allows you to increase engine efficiency, reduce gasoline consumption, optimize the operation of the gas distribution system and synchronize the interaction of all units. In addition to the above, BC reduces the concentration of harmful emissions. The onborder performs the functions of cruise control, climate control, and displays the information necessary for the driver, allowing him to make the right decisions on transport management and optimal movement along the chosen route. That is why all modern Lada Vesta models are equipped with BCs that successfully perform the functions assigned to them.

Additional Lada Vesta body electronics unit and LEDs
We all know very well how quickly the Lada Vesta was created, because the hype around this model was serious. On the other hand, all this resulted in the use of not entirely successful design solutions, which subsequently began to appear on production vehicles. One feature concerns the additional body electronics unit of the Lada Vesta.
Background
This situation arose with one of the Drive members, who is known there under the nickname Schoolboy11, with his Lada Vesta Red Menace car.
After purchasing Vesta, he decided to replace the size lamps with two-pin LEDs. He approached the choice of diodes responsibly - he purchased high-quality, proven products that were selected by professionals. Naturally, with them the exterior of the sedan was completely transformed.
Vesta looks much cooler with LEDs!
Problem
However, difficulties began very soon. One “fine” day, the dimensions on his car burned out, everywhere. Naturally, he tried to install standard lamps, but this did not help. As you know, in such situations everything is usually limited to replacing the fuses for the left and right side lights, which in Vesta’s manual are indicated by the symbols F16 and F17.
However, if you remove the cover that covers the fuses, the owners will find one very unpleasant surprise - fuses F16 and F17 are not there. There are not even contacts - just technological holes.
The cover that covers the fuses.
Separately, it is worth mentioning the lid itself. It is made the same as on Grant - from hard plastic. Moreover, plastic clips do not look very reliable and, as practice shows, they break quickly. On the other hand, the lid is equipped with a foam insert that serves as sound insulation.
Solution
If such a problem happens to you, it is recommended to contact the Lada dealership. In this case, you should not count on warranty service, since in this case there is no fault of the plant.
The thing is that the resistance of the diodes is greater than that of standard lamps, which is why the electronics unit burns out. In this case, there is a reckless decision by AvtoVAZ designers, who abandoned fuses and installed an electronic unit from the Renault Trafic model in Vesta.
Vesta’s design uses this electronics unit.
To restore the operation of the electrics, it is necessary to replace the additional body electronics unit of the Lada Vesta.
Where can I buy?
You can buy it at a dealership, but in the showroom it is usually very expensive. As an alternative site, you can use the resources presented in the table below. However, it is worth considering that prices may vary, and the part is not always available.

As you can see, the price of an additional Vesta body electronics unit is quite high, so the replacement is not cheap. However, all work in the service center takes no more than 60 minutes.
Conclusion
As Schoolboy11 noted, after such a nuisance, his opinion regarding modernization of the design was voiced to AvtoVAZ through a personal manager, after which the plant promised to consider this issue and make adjustments to the production process. This means that the installation of xenon and diodes in the future will have to take place without breakdowns.
If your Vesta is one of the first cars produced, before installing LEDs, consult the manager at the dealership. This will allow you to avoid unnecessary and quite significant expenses.

Errors P0522 and P0523 indicate problems.
Air pressure sensor
The service software displays a graph of DC voltage values at the node. Options:
- normal operation – 0.15-4 V;
- muffled internal combustion engine – above 4.5 V.
Circuit malfunctions are recorded by the ECU and entered into memory. OpenDiag reads the errors and displays their meaning.
Air flow sensor
The diagnostic software displays the cell signal voltage:
- 1-1.02 V – good condition;
- 1.03-1.04 V is the permissible limit;
- above 1.05 V – worn sensor.
At this value, the mass air flow sensor should be replaced.
The following elements can be analyzed:
- electronic accelerator;
- knock indicator;
- HF and RV position sensor.
Engine diagnostics via OBD2
The service capabilities of electronic components depend on the scanners and programs used. The OpenDiag application allows you to read engine readings at home, display recorded error codes and decipher them.
Service software allows you to monitor driving modes. Among the available ones: temperature, speed, throttle position, mixture quality and others.
For a detailed look at the M86 sensors and engine management system, check out the documentation below. “Euro-5 Electronic engine management system for 21129 cars of the LADA VESTA family with a controller – device and diagnostics.”
ABS diagnostics via OBD2 connector
The ABS system is diagnosed using a similar scheme. The connected scanner reads information from the brake control unit. Based on the data, a conclusion is made about the need for repairs.
- rotation speed of each wheel;
- valve condition;
- pump motor status.
The test will show the operation of the sensors, the condition of the circuit and contacts.
