OBD2 Scanners Defined

OBD2 is an abbreviation for Onboard Diagnostics 2, and the technology has been with us since 1988. It’s now a standardized system hidden behind the dashboard of cars and trucks. The OBD2 software in vehicles scans, regulates, and monitors its central systems and functions. It sends periodic commands to wherever is needed to help keep the vehicle running at optimal performance.

No car or truck is perfect, though. Sometimes, they malfunction or break down for no apparent reason. Warning lights warn, but they’re never specific. That’s where the OBD2 scanner comes in. It runs visible diagnostic tests that motorists and trained mechanics can easily understand.

3 Types of OBD2 Scanner

No two OBD2 scanners are the same, and there are three different types to choose from. It’s important to buy one that meets your needs, budget, and expectations.

The 3 types of OBD2 scanner are:

  1. Basic code readers
  2. DIY Scanners
  3. Professional scanners

DIY scanners read codes as well as offer other features. The most basic scanners, though, only show codes without any supporting data. That’s still useful, as explained below.

Ok, let’s now look at each of the above vehicle diagnostic tools in turn.

Editor’s Rating: 4.6/5

The Best Budget OBD2 Scanner goes to the universal FOXWELL NT301. The company designed this Engine Light Checker tool specifically for DIY home diagnostics. Let’s take a closer look.

  • Best feature 1: Comfortable handheld design with intuitive keypad
  • Best feature 2: Good sized 2.8” color display screen
  • Plus points: Battery-free, live graphic data, data logging, DTC lookup library, printer-ready
  • Minus points: Display brightness, poor instructions, compatibility issues

NT301 Professional Scanner Highlights

Today’s vehicle scanners have come a long way in a short space of time. The NT301 Mechanic OBD2 Scanner Code Reader here has a handy 2.8” color screen to display error codes. That means you can find out right away what caused your engine’s warning light to come on. You’ll know in an instant whether you can fix the problem, or need to take the vehicle to an auto repair shop.

This is a comfortable scanner to hold and has a simple, well-arranged keypad. It’s an easy tool to grasp and doesn’t need a battery to function. More highlights include live graphing data, data logging, and record OBD-II PIDs of Parameter IDs. Another welcome feature is the built-in DTC lookup library. What that does is offer repair help and suggestions for any of the detected codes.

The Not So Good

The display screen is okay, but it’s not as bright or as vibrant as the advertised images. The instructions are not the best and get plenty of complaints. Don’t try to decipher them if you find them overly vague. Look for a YouTube video tutorial instead. Some users complain about vehicle compatibility and connection types. Interested buyers should check with the seller if they’re unsure.

  • Best feature 1: Smart function/navigation buttons
  • Best feature 2: Large 4.0” TFT color screen

Diagnostic checks include SRS (airbag) issues, ABS brakes, transmission, and engine tests. Other diagnostic highlights are Read/Erase Codes, I/M readiness, Live Data on Graph, and much more.

The Not So Good

You need to receive updates via a Windows PC. That’s not ideal if you’re a dedicated Mac user, as it means you need to borrow someone’s PC for every update. Less experienced users find the included instruction vague in parts. It looks like the typical inadequate translation issue from Chinese to English. Lastly, downloading software updates can sometimes be tedious and time-consuming.

Innova 3150f Pro OBD2 ScannerView on Amazon

Editor’s Rating: 4.8/5

Motorists can check their engine warning lights with the Innova 3150f Pro OBD2 Scanner, Top Pick. It’s an excellent scanner that works on most vehicle types (see below).

  • Best feature 1: Large, 3.5” color LCD screen
  • Best feature 2: Bright LED OBD port connector
  • Plus points: Check engine light, ABS/SRS codes, oil light reset, battery initialization/reset

The Innova 3150f Pro OBD2 Scanner and code reader is a quality handheld diagnostics tool. It works with any OBDII car, truck, hybrid, and SUV from 1996 onward. You can use the 3150f to read a multitude of Fault Codes and Repair Solutions/Suggestions. Some of those include all Engine Warning Lights, ABS/SRS codes, Oil Light Resets, and Battery initialization.

This diagnostics tool even has a bright LED connector so that users can find the OBD port in the dark. The Bluetooth capability is another welcome feature, but it’s not perfect, see below. It lets you read codes via a smartphone or tablet using the Repair Solution App. It shows things like repair estimated costs, parts information, helpful articles, and some how-to videos.

The Not So Good

The free mobile app is useful, but it’s fiddly to navigate, and it doesn’t have a very intuitive layout. But it is an app, and that means future updates should see improvements. Bluetooth can also be tricky to connect at times. The 3150f Pro doesn’t come with paper instructions. Instead, new users must download them from the website. It’s not a major con, but some folks do prefer a booklet to hold.

The Not So Good

This scanner is easy to operate once you’re familiar with its features and functions. Unfortunately, the instructions are less novice-friendly than the tool.

BlueDriver Pro OBD2 Diagnostic Scan ToolView on Amazon

Editor’s Rating: 4.7/5

Consider the BlueDriver Pro OBD2 Diagnostic Scanner if you want an app-controlled tool. This model works with Android or iOS smartphones and tablets for viewing and saving data.

  • Best feature 1: Easy to install, simple to use
  • Best feature 2: Bluetooth connectivity
  • Plus points: User-friendly app (Android/iOS), codes + fixes, save & share, 24/7 support
  • Minus points: Small size (also a positive), quite expensive

This diagnostic tool is a small, yet powerful gadget for engine inspections. It plugs directly into a vehicle’s OBD port and transmits all data to your mobile device via Bluetooth. The app also comes with free lifetime updates. This tool offers potential repairs and fixes as they relate to the error codes. One of its main appeals is portability, and most people carry smartphones or tablets on their person.

The BlueDriver Pro works with Android or iOS devices. It lets you save data and has interactive live graphing. Some are sure to welcome the fact that North American engineers designed this scanner.

The Not So Good

This thing is small, and that’s half its appeal. But it’s also easy to lose or misplace. It would have been better if it came with a hook, loop, or keychain so that it wasn’t loose when not in use. Also, it may drain your battery eventually if you forget to take it out of the OBD port (easily done). The BlueDriver Pro is really good rather than excellent, and it’s quite expensive because of that.
