In my last post, I described the process of installing a multifunction steering wheel in my car. Everything went well and started working right away, but there was one more unfinished issue - the lack of indication of the operation of the CC and OS on the device. Even before installing the steering wheel, a super-wonderful entry appeared on the drive that you can flash the Vesta’s tidy yourself, and anyone can do this and you just need to find a USBDM programmer. In general, once again, thank you very much for this wonderful post. The author in it literally broke down the process of flashing the device firmware and attached the firmware files, in general, guys ura12345678 and RUPARADOX, thank you very much!
The search for a programmer led me to the well-known Aliexpress website. The cost of this programmer in China is around 800 rubles. After looking at different options and reading reviews, I decided to order here. On the 11th day of waiting, the programmer was in my hands:
I would like to warn you right away that this seller does not include a disk with the software and driver, so I am attaching links to my disk with the necessary files: - driver - flashing program - program for creating a backup of the current firmware version
If you decide to make a backup of the firmware, then here is a good article. Creating a backup is a slightly more complex and lengthy process than updating the device firmware itself. The main thing is to do everything strictly according to the instructions and take your time! I made a backup of my firmware, just in case... I would also like to note that I performed these operations on a PC running Windows 8.1 64-bit. By the way, users starting from Windows 8 and onwards, before installing drivers and software, do not forget to disable driver signature verification; how to do this, you can see, for example, here
When everything is installed, you can proceed directly to the firmware. First, let's disassemble the tidy. The back cover is secured exclusively with latches. If the tidy is of the old type (white), then we see a seal, which, as they say, can be easily peeled off by heating it with a hairdryer. I decided to try to do this. I’ll say this, I managed to peel it off without damaging it, but it’s noticeable that the seal is a little worn out, maybe I just overheated it:
In general, I’ll say this: in the end I broke the filling anyway :))) And there’s really no point in saving it, because The software version is written on the sticker on the back, i.e. You can still see the intervention:

Experts' opinions
In the first copies of the Lada Vesta, when the ignition was activated and the engine was started, the dashboard backlight did not light up. The reason was in the software, this function was not active by default.
When driving in sunny weather, during the daytime, it was difficult for drivers to read the readings of sensors, instruments, and indicators. For this reason, the owners did not notice the temperature rise, oil pressure warning lamp signals, etc.
After numerous requests to the manufacturer - AvtoVAZ, engineers developed and released new versions of firmware for the dashboard.
- when the ignition is activated, the instrument panel lights come on;
- green cruise control indicator, located in the right corner of the central well;
- actual mileage and fuel consumption are displayed online at the bottom of the central well.
On the first firmware of the Lada Vesta under the index “026” the indicated options were not available. The dashboard lights were activated together with the daytime running lights (DRLs), which was not always the case and there was no need for DRLs. In general, the “innovation” is positively approved by the owners of Lada Vesta. Now it has become much easier to read data and indicators from the instrument panel without distraction from driving the machine.
What can be changed in the firmware
For panels with white scales 8450007022, software - 26, 28, 35, 36:
- Activation of backlight during DRL.
- Activation of cruise control and speed limiter.
For panels with orange scales 8450030825, software - 11, 19, 22, 27:
- Activation of backlight during DRL.
- Display of REAL engine temperature.
- Activation of cruise control and speed limiter.

As of March 2021, the firmware of the instrument panel on the Lada Vesta and the activation of the backlight in DRL mode are not carried out due to identified errors in the software.
Conclusion
Installing new generation firmware is extremely important for monitoring instrument performance, monitoring engine temperature, and reducing eye strain.
During the flashing process, be extremely careful not to break the sequence of actions. Remember about the compatibility of new generation firmware. If you encounter any difficulties during the upgrade, contact a service station specialist for help.
Lada Vesta dashboard malfunctions
If the instrument panel is faulty, it is immediately noticeable; the following signs may indicate a problem:
- The contact of the instrument panel with the on-board electrical network is broken. The reason may be a broken wiring or damaged connectors or contacts.
- Sensor malfunction. The dashboard displays incorrect information if the crankshaft position sensor, speed sensor, or fuel level have failed.
- Mechanical damage, for example, exposure to constant vibrations or a strong impact in an accident.
- Faults related to the electronic microcircuit.
- Burnt-out indicator lights - in this case, the backlight disappears.
These malfunctions are obvious, but there are also those whose causes are not easy to understand.
Arrow indicators do not work
If the arrows on the instruments do not work, this may indicate a failure of the sensors responsible for these readings:
- The tachometer does not work. If the tachometer needle does not move, the cause of the malfunction is the device itself. If the crankshaft position sensor or electronic control unit fails, the engine cannot be started.
- The speedometer does not work. If the device is working but does not indicate speed, the cause is a faulty speed sensor. This will also be indicated by the ABS warning light.
- There is no antifreeze temperature reading. The temperature sensor is faulty and transmits incorrect readings to the control unit, which are displayed on the instrument panel.
- No fuel level readings. The unit with the fuel pump is faulty, the ECU does not receive a signal.
You can remove the instrument panel to check the functionality of the elements only after testing all sensors for malfunctions.

| 1. | Nikolay , 28 years old (drive2.ru), Sverdlovsk: I was one of the first to buy a car, the dashboard firmware was stock 026. I felt the lack of backlighting in the daytime catastrophically. On the advice of my comrades, I independently updated to version 036. The backlight has become adaptive; when the DRL is activated, the brightness decreases, which was so lacking before. |
| 2. | Mikhali , 33 years old (prom.ua), Samara: I have factory firmware with code 028. The problem with the backlight has already been fixed, but the cruise control indicator does not work stably and periodically gives an error. I plan to upgrade to version 036. |
| 3. | Alexander , 36 years old (autotoday.com), Krasnodar: I’ve been actively using Lada Vesta for four years now, code 026 is preinstalled. Of course, the problem with the backlight and DRL is familiar to me, but this does not prevent me from driving the car. |
| 4. | Valery , 47 years old (rozetka.ua), Rostov-on-Don: I didn’t know about the possibility of flashing before, my garage mates advised me. I drove with constant discomfort for two years, now I know how to fix the backlight “bug”. |
| 5. | Kirill , 45 years old, Kursk (avtoflit.com): when driving in sunny weather, the lack of illumination of the visor is obvious. Fuel level and consumption are not visible online. I heard that you can reflash the control unit with a new code. I'll contact the specialists at the service station. |
| 6. | Sergey , 43 years old, Saratov (autotoday.com): I didn’t update the program code myself, I turned to the workshop specialists for help. The guys did everything in 20 - 25 minutes in total. I am satisfied with the quality, there are no complaints about the operation of the electronic control unit. |
| 7. | Anatoly , 46 years old, Stavropol (drive2.ru): bought a car second-hand, one of the first models. I knew about the problem with the firmware, so the service station updated the code to version 036. Now the dashboard is brightly backlit; when the daytime running lights are activated, the brightness automatically decreases, which is very comfortable for the eyes. |
| Negative | |
| 8. | Vasily , 38 years old (prom.ua), Uralsk: I have negative experience of upgrading software code. The first time I flashed it myself, the installation went wrong. I went to the service station because the car couldn’t even start and had to be towed. |
| 9. | Nikiforovich , 44 years old, Moscow (avtoflit.com): even after updating to the latest current firmware version, the backlight randomly changes brightness. I don’t know what caused this. I contacted the service station after diagnostics and they recommended reinstalling the program code. |
| 10. | Vasily , 36 years old, St. Petersburg (drive2.ru): I updated to version 028 for the first time, the operation of the dashboard was unstable. On the recommendation of my comrades, I decided to re-flash it to 036, since now the equipment is working normally, without any breakdowns. |
| 11. | Gennady , 46 years old, Pskov (autotoday.com): even after updating to version 036, my backlight did not become adaptive. When activated, the DRL does not change brightness. Obviously, the problem is in the program code. |

Refinement of the instrument panel
Tuning the instrument panel on the Lada Vesta is no different from upgrading it on other VAZ models, although technologically it is a completely different panel. The main idea is to improve the backlight by replacing standard SMD LEDs with alternative ones. Decorative overlays and lighting modifications without firmware are also used.
Replacing backlight LEDs
Before you begin, you should take into account that you will have to work with a soldering iron; without knowledge of soldering technology, you can lose the backlight at best. At worst, the instrument panel will fail completely. To work, you will also need to purchase LEDs with a brightness of 3 to 15 lumens, depending on the level of desired brightness. During the tuning procedure, you need to follow some recommendations:
- be careful and careful not to damage the traces of the microcircuits;
- When soldering, observe the correct polarity of the LEDs;
- Do not hold the soldering iron tip for too long - the LEDs will fail due to overheating.
To make sure the LEDs are working properly, you will need a multimeter. The tester probes are connected to the “legs” of the diodes - a working diode will indicate the integrity of the circuit (a sound signal).
If you are satisfied with the brightness level of the backlight, but would like to change the color, it is not at all necessary to solder the LEDs, you can purchase a special overlay for the instrument cluster or make it yourself - the drawings are freely available. Color film may be used. Before assembling the instrument panel, you can additionally paint the wells.
Connecting the backlight to work with DRLs during the day
This can be done using firmware or a jumper directly on the electronic board. Any tampering with the electrical system will void the vehicle's warranty. In the absence of skills and experience, such actions can lead to failure of the instrument cluster.
The main task of the procedure is to solder a jumper from the contact of the LEDs responsible for illuminating the panel to the contacts of the LEDs responsible for illuminating the display of the on-board computer (lights up when the ignition key is turned). Any suitable piece of wire can be used as a jumper. At first glance it may seem complicated, but for experienced VAZ car owners such modifications are standard practice. Rarely do such requests come to specialized centers. The replacement of LEDs is not carried out by an official dealer, nor is the installation of all kinds of overlays.
