OBD2 scanners have become essential tools for car owners and mechanics alike. These devices interface with a vehicle’s onboard computer to read diagnostic trouble codes, helping identify issues before they turn into costly repairs. With cars growing more complex, having access to accurate diagnostics can save time and money.
There are various types of OBD2 scanners, from basic code readers to advanced scanners with live data streaming and manufacturer-specific code capabilities. Most vehicles manufactured after 1996 support the standard OBD2 protocol, making these scanners widely compatible. Choosing the right scanner depends on the depth of information you want and how much control you expect over the diagnostic process.
Best OBD2 Scanners
- FIXD Bluetooth OBD2 Scanner
- ANCEL AD310 OBD2 Scanner
- BlueDriver OBD2 Scanner
- FOXWELL NT301 OBD2 Scanner
- ANCEL AD410 OBD2 Scanner
I’ve researched and tested a selection of reliable OBD2 scanners to help you quickly diagnose vehicle issues.
These tools vary in features and price, making it easier to find one that fits your needs and budget. Below are the best options I recommend for accurate and hassle-free car diagnostics.
1. FIXD Bluetooth OBD2 Scanner
This scanner is a solid choice if you want straightforward diagnostics and real-time alerts without the need for a mechanic.
Pros
● Easy wireless setup and smartphone app interface
● Translates engine codes into simple language
● Tracks maintenance and provides repair cost estimates
Cons
● Bluetooth connection can be inconsistent at times
● Some codes are generic and less detailed
● Requires app account and occasionally prompts for email verification
I plugged FIXD into my car’s OBD2 port and paired it with my phone quickly. The app’s clear explanations helped me understand the issues under the hood without jargon. It saved me a trip to the shop when the check engine light came on.
Maintenance reminders were a handy feature; it nudged me about oil changes and battery health. However, the Bluetooth connection occasionally dropped, which meant I had to re-pair the device a couple of times to get fresh readings.
While the scanner covers many problems, some of the more serious issues got vague alerts that didn’t specify exact fixes. Despite this, the ability to clear codes directly from the app after repairs made it convenient to stay on top of car health. Overall, it’s a user-friendly tool for anyone wanting basic but useful diagnostics.
2. ANCEL AD310 OBD2 Scanner
A solid choice for anyone wanting a straightforward, reliable OBD2 scanner that quickly identifies check engine light issues.
Pros
● Accurate and fast trouble code reading
● Compact, sturdy design with a long cable
● No batteries needed, powers through vehicle connection
Cons
● Display and interface feel basic compared to modern scanners
● Instructions could be clearer for first-time users
● Limited advanced features for in-depth diagnostics
Plugging in the ANCEL AD310 was straightforward—I just connected it under the dashboard and powered on the car. The scanner immediately pulled up the trouble codes, which saved me a trip to the shop. It quickly pinpointed an oil sender unit issue on my truck, which I fixed myself with the info.
The durable cable and solid build gave me confidence while maneuvering under the hood. It’s not a touchscreen or color display, but the screen clarity made reading codes easy enough without eye strain.
This tool is perfect if you want a no-nonsense reader that keeps things simple. It lacks some extra software bells, but for basic engine diagnostics, it works flawlessly and unpacks quickly when I need it.
3. BlueDriver OBD2 Scanner
If you want a reliable, user-friendly scanner that provides deep diagnostics without subscription fees, BlueDriver is a solid choice.
Pros
● Accurate and detailed diagnostics beyond basic codes
● Wireless Bluetooth connection works smoothly with phones
● Access to repair reports and live data makes troubleshooting easier
Cons
● You might forget to unplug it after use
● Advanced features mostly tailored to popular car brands
● Occasional app interface quirks can slow down navigation
Using BlueDriver felt straightforward right from the start. It quickly connected to my phone and pulled detailed trouble codes that many basic scanners miss. The repair reports gave clear explanations and fix suggestions, which helped me understand issues without needing to guess.
The wireless design is a big plus since I didn’t have to deal with cables cluttering my workspace. The live data feature was handy too, letting me watch engine parameters in real-time while driving. It gave me more insight into my car’s health beyond just error codes.
One minor downside was that the app sometimes felt a bit slow when browsing different options. Also, because it’s optimized for many popular vehicle brands, there can be occasional limits if your car is less common. Still, for the price and functionality, BlueDriver stands out as a dependable tool in everyday diagnostics.
4. FOXWELL NT301 OBD2 Scanner
This scanner is a solid choice if you need an easy-to-use, reliable tool for reading and clearing engine codes without extra fuss.

I found the NT301 straightforward right out of the box. The buttons are tactile, and the menu is intuitive, which makes scanning quick even if you’re not a mechanic. Plugging in doesn’t feel loose or fragile.
Live sensor data is displayed with helpful graphs, which helped me track intermittent issues. Code definitions appeared immediately with helpful guidance on likely causes, saving me time searching online.
The readiness check with color LEDs and audible indicator was nice to have for emissions. However, I did notice it won’t scan ABS or airbag systems, so you need a more advanced unit for full diagnostics.
If you need a dependable, no-nonsense scanner for engine codes and readiness, the FOXWELL NT301 performs well in everyday garage use.

Using the ANCEL AD410 was straightforward right out of the box. I appreciated how it powered directly from my car’s OBDII port, eliminating the hassle of charging or replacing batteries. The interface is simple and intuitive, making it quick to read and clear trouble codes.
The scanner’s ability to provide code definitions saved me from endless Googling. It helped me understand pending and stored codes immediately, which is handy before deciding on any repairs. The monitor readiness check is practical for smog test prep.
