Vlad Chizhov’s “Solved” program: a complete guide to car diagnostics

In this article we will look at:

• 🔧 What “Reshala”** can do and how it differs from its analogues
• 💻 System requirements** and adapter compatibility
• ⚙️ Step-by-step instructions** for installation and configuration
• ⚠️ Typical user mistakes** and how to avoid them
• 📊 Comparison** with other diagnostic programs

We will pay special attention to the legality of use and safety for car electronics - topics that are often overlooked in reviews.

What is the “Solved” program and why is it needed?

"Resolved" is multifunctional diagnostic software, developed by a Russian specialist Vlad Chizhov for working with automotive electronic systems. Unlike universal scanners like Torque Pro or FORScan, the program is focused on deep diagnostics of domestic and some foreign cars, including:

• 🚗 VAZ (from classics to modern models on the platform Lada Vesta)
• 🚙 GAS (including Volga Siber and Gazelle Next)
• 🚛 UAZ (SUVs and commercial vehicles)
• 🔌 Some models Renault, Nissan and KIA/Hyundai (with restrictions)

Key benefit: support K-Line and CAN protocols, which allows you to read data not only through a standard connector OBD-II, but also connect directly to control units. For example, for VAZ 2110 the program can:

• 🔍 Show real parameters** of sensors (temperature, pressure, throttle position)
• ⚡ Reset errors P0100-P0600 without a trip to the service center
• 🔄 Program immobilizer keys (on some models)
• 📈 Build system operation graphs in real time

However, it is important to understand: “I decided” is not official software from car manufacturers. It was created by enthusiasts based on reverse engineering, therefore:

⚠️ Attention: Using the program on new vehicles (manufactured after 2020) may result in ECU lock due to updated security systems. Before connecting, check the compatibility of your model on the forums!

System requirements and compatible hardware

To use Solver you will need:

Critical point - adapter selection. Cheap Chinese ELM327 (price up to 500₽) often do not support the protocol K-Line, necessary for diagnosing old cars. Optimal options:

• 🔌 VGate iCar2 Wi-Fi (~3500₽) - works with all protocols, stable connection
• 🔌 OpenPort 2.0 (~8000₽) - professional solution for service stations, supports J2534
• 🔌 USB Auto COM (~1200₽) - a budget option for VAZ and GAS

Before purchasing an adapter, check its compatibility with your car model. For example, for Lada Vesta with the system ERA-GLONASS you will need an adapter that supports CAN FD.

Step-by-step instructions for installation and configuration

Installation of "Reshaly" consists of several stages. Follow the instructions strictly in order to avoid connection errors.

Step 1. Download the program

Reshala does not have an official website - distribution is carried out by enthusiasts through forums (Drive2, Autolada.ru) and telegram channels. Current versions (for 2026) can be found:

• 🔗 B Telegram channel of Vlad Chizhov (checked for viruses)
• 🔗 On the forum Drive2 in the topic “VAZ diagnostics”
• 🔗 Archived Mail.ru Cloud (links are updated once a month)

Step 2: Installing adapter drivers

Before connecting the adapter to the car, you need to install the drivers:

1. Connect the adapter to a USB port on your computer.
2. Run Device Manager (Win + X → Device Manager).
3. Look for the device with the exclamation point (usually under “Ports (COM and LPT)”).
4. Update the driver manually by specifying the folder with drivers from the program archive.

Step 3. Connection setup

After installing the drivers:

1. Run the program Reshala.exe on behalf of the administrator.
2. On the menu Settings → Port select the COM port of your adapter (usually COM3 or COM4).
3. Set the baud rate: 38400 baud for K-Line, 500000 baud for CAN.
4. Turn on the car's ignition (without starting the engine!).
5. Connect the adapter to the diagnostic connector (usually located under the steering wheel or in the glove compartment).

Step 4: Reading Errors and Parameters

After successful connection:

1. In the main program window, click Count errors.
2. Wait for the scan to complete (may take up to 2 minutes).
3. Errors will be displayed as codes (for example, P0300 — misfires).
4. For detailed information, click on the error - the program will show possible causes.

An example of error decoding:

Code: P0171
Description: Mixture too lean (bank 1)
Possible reasons:
- Air leak in the intake manifold
- Malfunction of the mass air flow sensor (MAF)
- Clogged injectors
- Leakage of the intake system

Typical user mistakes and how to avoid them

Even experienced car owners encounter problems when working with Reshala. Here are the most common errors and ways to solve them:

1. The program does not connect to the car

• 🔌 Reason: Incompatible adapter or incorrect port settings.
• 🛠️ Solution: Use an adapter that supports K-Line (for example, VGate iCar2) and check the data transfer speed.

2. Errors in reading control units

• 🔌 Reason: Low on-board voltage (less than 11.5V) or poor contact in the connector.
• 🛠️ Solution: Recharge the battery or clean the diagnostic connector contacts with alcohol.

3. The program produces incorrect data

• 🔌 Reason: Conflict with other diagnostic programs (for example, OpenDiag or ScanMaster).
• 🛠️ Solution: Close all background processes via Task Manager and restart Solved.

4. After resetting the errors, they appear again

• 🔌 Reason: The error has not been physically corrected (for example, the sensor is faulty).
• 🛠️ Solution: Have the vehicle checked mechanically or contact a service center.

⚠️ Attention: Never update the firmware of control units via Reshala if you are not sure of its compatibility! An incorrect update may result in complete ECU failure and the need for flashing in the service (cost from 5000₽).

Comparison of "Solved" with other diagnostic programs

To understand whether Reshala is right for you, let’s compare it with popular analogues:

Reshala beats its competitors in two aspects:

1. Free - no hidden fees or subscriptions.
2. Support for older cars through K-Line, which is critical for owners VAZ 2109 or GAZ 3110.

However, for modern foreign cars (for example, Toyota Camry 2023) better to choose FORScan or OpenDiag — they are regularly updated and support new protocols.

User reviews and expert opinion

Opinions about “Reshal” are divided: from enthusiastic to sharply negative. After analyzing the reviews on the forums (Drive2, Autolada.ru, 4PDA), we have highlighted the key pros and cons:

Pros (according to users):

• 👍 “I saved 3000₽ on diagnostics in the service - I found the problem with the air flow sensor myself” (VAZ 2114, 2012)
• 👍 “Works even on Windows XP - does not require a powerful PC” (GAZ 31105, 2008)
• 👍 “Shows parameters in real time, which is not the case in cheap ELM scanners” (UAZ Patriot, 2015)

Cons (common complaints):

• 👎 "Doesn't work with Lada Vesta FL 2021 - gives a connection error"
• 👎 “The interface is outdated, there is no Russian-language help”
• 👎 “After resetting errors P0420 (catalyst) it returns after 50 km"

Expert opinion (service station master with 10 years of experience):

"Reshala" is a good tool for preliminary diagnostics, but not a panacea. It helps narrow down the troubleshooting, but accurate repairs often require professional equipment like Bosch KTS or Launch X431. For example, if the program shows an error P0340 (phase sensor), this does not always mean that the sensor is faulty - the problem may be in the wiring or the ECU itself. Always double-check the data mechanically!

Legality and safety of use

The main question that worries users: Is it legal to use Reshala? From a legal point of view:

• ⚖️ The program does not violate copyright - it was written from scratch Vlad Chizhov (not a hacked version of other software).
• ⚖️ Diagnostics own car is not prohibited by law.
• ⚖️ However, using the program for commercial diagnostics (for example, in an unlicensed service) may lead to claims from automakers.

Risks for the car:

• ⚡ Electrical jumps - cheap adapters can cause damage ECU with unstable voltage.
• 🔄 Incorrect firmware - if you try to update the control unit software with unofficial firmware, this may damage it.
• 🔒 Immobilizer lock - on some cars (Renault Duster, Nissan Almera) incorrect connection may activate protection.

To minimize risks:

Alternative legal solutions:

• 🔧 OpenDiag Free - free version with support VAZ and GAS.
• 🔧 ScanTool OBDLink - official software for adapters OBDLink (cost ~3000₽).
• 🔧 Autocom CDP Pro — professional software for service stations (license from RUB 20,000).
