10 Best ODB2 Readers Reviewed & Rated in 2019
You’ve just gotten your paycheck, paid all the bills, stashed a little cash in the bank and finally have enough extra to get that laptop you’ve had your eye on. Then, all of a sudden, the check engine light comes on! Just your luck! Now you have to spend that extra cash just to find out what’s wrong with your car. Or do you? If you have an OBD2 scanner, you could find out what the problem is and possibly even fix it yourself, which would save you time and money.
An OBD2 scanner is a tool that can read and clear codes from your vehicle’s onboard computer. Thanks to standards set by the Society of Automotive Engineers (SAE), which were implemented on January 1, 1996, by the Environmental Protection Agency and the California Air Resources Board, all car and truck models produced in 1996 and after share a standardized system for self-diagnostics and reporting known as Onboard Diagnostics II. This allows OBD2 scanners to work on all cars models after 1996 and can help you figure out exactly why that check engine light is on.

Criteria Used in Evaluation of the Best OBD2 Scanners
Types of OBD2 Scanners
Although all scanners are designed to read your vehicle’s onboard diagnostics, some are much more advanced than others.
OBD2 Code Reader – A basic, no-frills device is the OBD2 code reader, which is fairly inexpensive and has the capability of reading and clearing codes from all vehicles that are equipped with OBD2. They usually offer limited, if any, information about manufacturer-specific codes or any other information. These are basic tools used to let you know if there is a trouble code or if your vehicle needs to be taken to a mechanic to get diagnosed.
OBD2 Scan Tool – Scan tools may be more expensive, but they also offer a variety of features that can be helpful with finding a problem and getting it fixed. Some of these features include:
- Access to advanced troubleshooting information
- Data on manufacturer-specific codes
- Information about live and recorded data
- Ability to log and store data about your vehicle
- Can print results
- Detects and resets airbag, ABS, and other systems
- Displays diagnostic code definitions on screen
- Retrieves the vehicles VIN
- Check soft and pending codes
OBD2 scan tools also come in two different forms, PC-based OBD2 scanners, and handheld auto scanners. PC-based scanners are usually less expensive than handheld scanners and use Bluetooth to transform your tablet, phone, or laptop into an advanced diagnostic tool that can provide highly reliable information and perform many of the same functions you find in high-end OBD2 scanners. Handheld scanners are the tool of choice for professional mechanics. They are powerful and can diagnose brake, engine, and transmission problems. They are more expensive but provide clearer and more detailed information.
What good is an OBD2 reader if you don’t understand the information that is being provided? Whether this is because the screen is so small, you can barely make out what is being displayed or because the language being used is confusing, the main purpose of an OBD2 reader is to provide you with comprehensible data. Make sure that the reader of your choice has a large, easy-to-read screen and uses simple language to present information in a way that you are comfortable with. Some scanners even allow you to customize the way data is displayed, which can save you a lot of time and prevent possible mistakes.
The ability to save data from your vehicle’s diagnostic tests is an important feature that can help you in the long run. You may think that if the issue is solved, then why do you need to save the information about this issue? Mechanics understand that knowing what problems your vehicle has had in chronological order is important for preventing future issues. It means lesser questions for you and more information for the mechanic to work from.
Because of standards set in 1996, all vehicles sold in the US on that year and after must be equipped with an on-board diagnostic system that makes it easier for professional auto mechanics and consumers to find possible issues with their vehicles. Although OBD2 devices share a universal connector that can be connected to the vehicle’s on-board diagnostic system, they are not all compatible with all vehicles. To ensure that your scanner will work with your vehicle, you need to find out which signal protocol is met. A good reader will support all five basic signal protocols, which will enable it to work on all vehicles made in the US in 1996 and later.
Nobody wants to spend money on a tool or device that will be outdated and useless after a few years. Many of today’s readers can go through upgrades and updates. This can be helpful in many ways and allows you to use your OBD2 reader for many years to come. Some of these upgrades help get rid of bugs that can cause problems with your scanner. Updates are important because they allow your device to work on the newest vehicles and adhere to any changes that have been made to the standards.
The more advanced the OBD2 scanner is, the more scanning options it will provide. For some people, a simple scan of the engine is enough. For others who prefer fixing the problem themselves, a more advanced scan can provide you with more information about other issues including ABS brakes, airbags, coolant temperature, air flow rate, calculated load value, and more.
Ease of Use
Not everyone plans on fixing their vehicle’s problems themselves. Some people just want basic information, so they know what the issue is and if they need a professional to take a look at it. Some people just want to know if their vehicle will pass the emissions test or not. Look for OBD2 devices that use simple English and feature a built-in database to provide you with code error definitions. This will save you time from having to Google it and possibly get the wrong information.
Frequently Asked Questions
Q: How do I know if an OBD2 scanner is compatible with my vehicle?
The best way to ensure that a scanner will work with your vehicle is to read the owner’s manual. Most manufacturers will claim that their scanner will work on all 1996 US vehicles and newer, but that is not always the case. Another way to find out if your scanner will work on your vehicle is to which OBD2 protocol it supports:
- SAE J1850 PWM – this support vehicles made by Ford and uses PINS 1 and 2
- SAE J1850 VPW – supports cars and light trucks made by General Motors and uses PIN 1
- ISO9141-2 – supports cars made in Europe between 2000 and 2004 and uses PIN 7 and 15
- ISO14230-4 (KWP2000) – supports some vehicles made in Asia and uses PIN 7
- ISO 15765-4/SAE J2480 – supports all vehicles sold in the US after 2008 and uses PINS 6 and 14
Q: I’m no mechanic and have no desire even to try working on my car. Do I still need OBD2 scanner and why?
Although you have no desire to physically work on your vehicle yourself, you should stay informed about any issues it may have. Let’s face it; not all mechanics are honest. The more you know about your car’s issues, the less likely you are to get ripped off. Besides, some issues which seem minor at first can evolve into a major problem that costs a lot of money if not taken care of immediately. Here are some basic reasons why you should have an OBDII reader:
- Most modern vehicles have computer systems that control the ignition system, automatic transmission, ABD, fuel infections, airbags, and more. An OBD2 can scan the entire electronic system, find problems, and inform you about the issue.
- An OBD2 scanner can let you know if your car can pass the emissions readiness test. This allows you to fix any problems before going in.
- OBD2 readers can detect possible malfunctions by displaying problem codes. Some scan tools even have a database from which you can get the definition of the problem code and how to fix it. If your OBD2 reader does not have this option, you find problem code definition online.
- OBD2 scanner can save you time and money in the long run. Being able to determine what the problem is will give you peace of mind. You’ll also know if the issue is an easy fix or something that needs professional assistance. You’ll find that there are some issues you can troubleshoot yourself with a little help from the internet.
Q: What should I look for in an OBD2 scanner?
That’s a good question considering that there are so many different types to choose from. If you want something easy that can read and erase codes, most basic code reader will do the job. However, if you’re willing to spend a few extra dollars to get better features, here are some things you should look for:
