Lada Vesta 2022 - 2022, 2022 2021 is a sedan or station wagon. The SV Cross modification, presented as a new generation crossover, also began to be produced. Regardless of the model type, the installer and fuses of the Lada Vesta remain the same. They differ slightly in the type of configuration.
The machine contains 2 blocks of fusible protective elements and the same number with a relay. One of them can be found inside the car, and the second in the engine compartment. The selection of fuses in them differs depending on the role being protected by the electrical circuit. A detailed diagram and its explanation can be seen below.
Block in the cabin
The 2017-2018 Vesta modification contains the largest number of fuses and relays. Most of them are responsible for the safe operation of electrical circuits of devices inside the cabin, as well as those that control the vehicle’s electronics. A comfortable ride and driving safety depend on them.
You can find this block to the left of the dashboard, just below the level of the steering wheel. The lid is indicated by special plastic clips. Below it is a diagram describing its contents.

Reviews
| № | Positive |
| 1. | Georgy Nikolaevich , 42 years old (drive2.ru): the car has been three years old since purchase, I haven’t made any investments, only scheduled maintenance. The fuses are all standard, nothing has been changed. |
| 2. | Mikhail , 48 years old (prom.ua): in two years I replaced two power modules once. I didn’t contact the service, I limited myself to my experience and skills. |
| 3. | Sasha , 38 years old (autotoday.com): There are no complaints about the standard power modules yet, the car is only a year old, but I heard that you can install a unit from Renault Duster, Logan of the second generation. |
| 4. | Kirill , 45 years old (rozetka.ua): mileage 75,000 km, only recently replaced five power modules with new ones. I believe that a resource of 75,000 km is more than enough for domestic transport. Of course, there is still a long way to go to reach foreign brands, but this is progress. |
| 5. | Petrovich , 44 years old, (avtoflit.com): I bought the car second-hand, good condition, five years old. I didn’t do anything to the power system, the units are operating normally. |
| 6. | Nikolaevich , 45 years old, (autotoday.com): I am satisfied with the quality of manufacturing and assembly of the Lada Vesta, no comments. I fix minor damage myself. |
| 7. | Vasilievich , 41 years old, (drive2.ru): the car is four years old, only recently replaced three relays - breakers in the engine compartment. Good build quality Lada. |
| Negative | |
| 8. | Nikiforovich , 49 years old (prom.ua): problems with the power system began after buying the car. I repeatedly contacted the service station due to burnt-out power modules. The problem is still not resolved. |
| 9. | Nikolai Semenovich , 46 years old, (avtoflit.com): I do not recommend standard fuse blocks for the Lada Vesta. If possible, replace with new ones from Renault Duster, Logan of the second generation. |
| 10. | Vyacheslav Petrovich , 47 years old, (drive2.ru): the car is new, but the weak points are inherited from previous generations. |
| 11. | Stanislav Vasilyevich , 39 years old, (autotoday.com): after two years of operation, the car began to crumble in the literal sense of the word. The build quality is still raw and needs improvement. |

Causes and solutions
The first problem and the second problem can only be encountered by a beginner who has this first car and has not yet read the instructions for it. The fact is that the standard connection of the stereo system implies its operation only when the ignition is turned on. That is, I got into the car, started the engine (or simply turned the key in the lock), and turned on the music. This is done to save battery charge. But if you are not satisfied with this situation, then contact electricians who will quickly make the device “independent”.
The next problem is a barely noticeable indication on the display. This happens exclusively in cold weather, at sub-zero temperatures. The problem is easily solved by warming up the interior and within 15 minutes everything returns to normal. It’s hard to call this a malfunction; most likely, this is a feature of the displays.
It happens that when you briefly press the power button, the device does not respond. In such a situation, the advice is simple - hold the key for a few seconds. Perhaps these are isolated cases associated with a specific device, but this still happens sometimes.
In some situations, the car radio may have a software failure and not respond to attempts to turn it on. To do this, a reset is provided on the front panel. Next to the power button there is a hole in which the reset key is located. To activate it, you need to gently press it with something sharp and hold it for a few seconds. Sometimes this helps to “reanimate” the radio.
LADA VESTA. DIAGNOSTIC CARDS OF THE M86 ENGINE CONTROLLER 21129 EURO-5
Map A-4
Checking the main relay and power circuit
Circuit Description
When the ignition is turned on, voltage from the ignition switch is supplied to contact “X1.1/A5” of the controller. The controller, through contact “X1.1/J3”, turns on the main relay, through which the supply voltage is supplied to contacts “X1.1/L3” and “X1.1/K3” of the controller, as well as to sensors and some controlled devices (canister purge valve , injectors, relays).
Description of checks
1 Voltage is supplied to contact “X1.1/A5” of the controller from the ignition switch.
2 The diagnostic device shows the voltage of the on-board network, determined by the controller from the voltage at contacts “X1.1/L3” and “X1.1/K3”. It should not differ by more than 1 V from the battery voltage.
3 There should be battery voltage present at the contacts of the harness block to terminals “85” and “30” of the relay. If power is present on both contacts, the light of the probe connected to ground should light up when you touch them.
4 The previous test determined the presence of voltage at the contact of the harness block to terminal “85” of the relay. This test monitors the main relay control circuit, which must be closed to ground by the controller.
5 The serviceability of the main relay is checked.
The reason for the incorrect value of the on-board voltage, determined by the controller from the voltage at contacts “X1.1/L3” and “X1.1/K3”, may be a short to ground in the power supply circuits to the relays and actuators, as well as incorrectly connected anti-theft devices.
Map A-5
Checking the electrical circuit of the fuel supply system.
Circuit Description
When the ignition is turned on, the controller turns on the electric fuel pump relay and the electric fuel pump starts working. If there are no reference pulses from the crankshaft position sensor (the engine is not running), the controller turns off the electric fuel pump through
2 s after turning on the ignition.
Description of checks
The sequence corresponds to the numbers on the card.
1 The electric fuel pump is forced on.
2 Check the presence of +12 V voltage at the contacts of the electric fuel pump relay.
3 When the ignition is turned on and the engine is cranked, the controller should turn on the electric fuel pump.
