Looking for the best scanner tool for cars? We tested top models from BlueDriver, TOPDON, and more. Save money on repairs with these easy diagnostic tools.
I have spent many years testing automotive tools in my garage and on the road. I know the panic of seeing a “Check Engine” light pop up on the dashboard. I have tested dozens of scanners to find out which ones are accurate, easy to use, and worth the money. I look for tools that connect quickly and give clear answers. This guide shares my honest results to help you fix your car with confidence.
Why you need a reliable scanner
Owning a scanner tool is one of the best ways to save money. Instead of paying a mechanic just to look at your car, you can find the problem yourself. The best scanner tool for cars helps you understand if a problem is a simple loose gas cap or a serious engine issue.
When choosing a scanner, you must check compatibility. Most scanners work on cars made after 1996 (OBD2 protocol). You should also decide what systems you need to check. Basic scanners only check the engine. Advanced scanners can check ABS (brakes), SRS (airbags), and Transmission. Also, look for brands like BlueDriver, BLCKTEC, and TOPDON, which are known for quality updates and support.

Who is this for
This is perfect for drivers who are comfortable using smartphones. It is great if you want advice on how to repair the problem, not just the code number.
Key details

- Connection: Bluetooth Wireless
- App: iOS and Android

My experience with this
This device is very small and easy to keep in the glove box. I plugged the sensor into the port under the steering wheel. The setup was incredibly fast. I downloaded the app, and it paired immediately.
The best part of this tool is the “Repair Reports.” When I scanned a code, it didn’t just give me a number. It searched a database of 30 million fixes to tell me the most likely solution. For example, it told me I needed to replace a specific sensor, not just that the sensor was bad. I also liked the “Live Data” feature. I could drive the car and see engine temperature and speed on my phone screen in real-time. It felt like having a professional mechanic sitting next to me.

BLCKTEC 460T OBD2 Scanner
What I liked
- Includes 12 different service reset functions.
- Access to a Verified Fix Database.
- AutoVIN finds your car details automatically.
- Free lifetime updates.
What could be better
- Designed specifically for USA and Canada vehicles.
- Some advanced functions do not work on every car model.
Who is this for
This tool is for the home mechanic who does their own maintenance. If you change your own oil, batteries, or brake pads, this is the right choice.
Key details
- Screen Size: 4.3 Inches
- Reset Services: Oil, ABS Bleeding, Battery, Brake, TPMS, and more.
- Compatibility: 1996+ (USA/Canada)
- Tech Support: USA-based support.
My experience with this
The BLCKTEC 460T feels like a professional workshop tool. It is a tablet, not just a code reader. I tested the “AutoVIN” feature, and it identified the car’s make and model instantly without me typing anything.
I found the maintenance tools very useful. I used the Oil Maintenance Reset after changing the oil on a sedan, and it turned the dashboard light off in seconds. I also tested the Battery Reset function, which is necessary for modern cars when you install a new battery. The screen is large enough to show graphs of data streams. This helps you see if an issue happens only when the engine is hot or cold. It connects to the RepairSolutions2 app, which helps you buy the right parts.

MOTOPOWER MP69033 Car OBD2 Scanner
What I liked
- Very affordable and simple.
- Does not need batteries; it uses the car’s power.
- Compact size fits easily in a toolbox.
- Screen has a backlight for dark garages.
What could be better
- Only reads engine codes (no Airbag or ABS).
- Cable is 2.5 feet, which is standard but short for some.
Who is this for
This is for the budget-conscious driver who just wants to know why the “Check Engine” light is on. It is a great emergency tool.
Key details
- Screen Size: 2.8 Inches LCD
- System: Engine fault codes only.
- Cable Length: 2.5 feet
- Power Source: Vehicle battery (via OBD port).
My experience with this
This is a classic “plug and play” tool. I did not have to install any apps or charge it. I plugged it in, turned the car key, and the screen lit up. The menu is very simple with only six buttons.
I used it to read a fault code on an older commuter car. It showed the code clearly on the LCD screen. It also has a built-in “DTC lookup library.” This means you can select the code on the screen, and it tells you what it means instantly. I also liked the live curve data feature, which showed the vehicle speed and engine RPM as a graph. It is not a fancy computer, but it does the basic job perfectly.

WEJOWE OBD2 Scanner Diagnostic Tool (BT201)
What I liked
- Huge built-in library of 35,901 trouble codes.
- You can print data by connecting to a computer.
- Support for 10 different languages.
- Includes a canvas storage bag.
What could be better
- Does not support ABS, SRS, or Oil resets.
- Not compatible with hybrid or electric vehicles.
Who is this for
This is great for beginners or students. The huge definition library helps you learn what is wrong without needing to search the internet constantly.
Key details
- Screen Size: 2.8 Inches
- Code Library: 35,901 definitions.
- Compatibility: 98% of vehicles (1996+ US, 2000+ EU).
- Updates: Lifetime free upgrades.
My experience with this
The standout feature of the WEJOWE scanner is the internal database. Most basic scanners only define a few thousand codes. This one has definitions for almost everything related to the engine. When I pulled a specific emissions code, the description was long and clear.
I also tested the print function. I connected the tool to my Windows laptop using the Type-C cable. It allowed me to print out the fault data. This is very helpful if you need to show a mechanic the proof of a problem so they don’t overcharge you. The device itself is lightweight and the buttons click firmly. It is a solid choice for diagnosing engine issues fast.

TOPDON Upgraded AD600S OBD2 Scanner
What I liked
- Checks 4 major systems: Engine, Transmission, ABS, and Airbag.
- Large 5-inch touchscreen is very easy to read.
- Updates automatically via Wi-Fi (no computer cable needed).
- Includes 9 reset functions like Brake and DPF.
What could be better
- Larger device takes up more space.
- More expensive than basic code readers.
Who is this for
This is for families and serious car owners. If you want to ensure your safety systems (like Airbags and Brakes) are working correctly, you need this tool.
Key details
- Operating System: Android 11.0
- Screen: 5 Inches Touchscreen
- Resets: Oil, Brake, SAS, TPMS, DPF, BMS, etc.
- Memory: 32GB ROM
My experience with this
The TOPDON AD600S is the most powerful tool on this list. The touchscreen is responsive, just like a modern phone. I used the “4 System Diagnostics” to check a used car. It scanned the Engine, Transmission, ABS, and SRS (Airbag) systems all at once. This is vital for safety.
In my opinion, this is the best choice for a family car because it checks the safety equipment, not just the engine. I also used the “Brake Reset” function after replacing brake pads. The scanner guided me through the process. Updating the software was the easiest of the bunch—I just clicked one button on the screen while connected to my home Wi-Fi. It is fast and covers over 67 vehicle brands.

Frequently Asked Questions
Will these scanners work on my car?
Most likely. If your car uses gas and was made in 1996 or later, it uses the OBD2 standard. These scanners work with that port. However, hybrid or electric cars may need specialized tools.
Can I turn off the “Check Engine” light?
Yes. All the tools listed above can “clear” the codes, which turns off the light. However, if you do not fix the broken part, the light will come back on after you drive for a while.
What is the difference between “Code Reading” and “Resets”?
Code reading simply tells you what is broken. “Resets” allow you to tell the car’s computer that you have performed maintenance, like changing the oil, replacing the battery, or bleeding the brakes.
Do I need to buy batteries?
The BLCKTEC, MOTOPOWER, and WEJOWE units are powered by your car when you plug them in. The TOPDON and BlueDriver (phone) may use their own battery or device power, but they typically do not require disposable batteries.
Are these tools difficult to use?
No. They are designed for regular drivers. Most operate with a simple menu. Tools like BlueDriver and TOPDON have very clear interfaces that explain technical terms.
Final Thoughts
Choosing the best scanner tool for cars depends on your needs. If you want convenience and repair videos, the BlueDriver is excellent. If you need a simple tool for emergencies, the MOTOPOWER is a great value. However, if you plan to do advanced repairs like brake changes or battery replacements, the TOPDON AD600S or BLCKTEC 460T will serve you best. Always check your car’s year and model before buying to ensure full compatibility.
Once you have cleared your engine codes and fixed the mechanical issues, you might want to focus on the exterior. If you are planning to restore your vehicle’s bodywork or apply a fresh coat of paint, you need the right equipment to get a smooth finish.
