Best OBD II (OBD2) Scanner 2017
More and more, today’s car owners are learning that they can save hundreds or even thousands of dollars by diagnosing and analyzing the control and power systems in their vehicle. Many dealerships and unscrupulous service stations charge $100 or more to read and interpret OBD II data from your vehicle. With a home OBD II scanner, you can quickly and easily receive the same information, often allowing you to make easy and less-expensive repairs yourself.
Over 40 years ago, auto manufacturers realized that drivers and mechanics could benefit from emerging computer technologies to record and track a number of subsystems in the car. While the original OBD sensors were primitive and crude, all of today’s modern vehicles now are required by law to have advanced OBD sensor systems installed.

Our OBD II (OBD2) Scanner Reviews
This bright-red scanner fits easily in the palm of your hand and can be clipped to a keyring or kept in a glove box. Within seconds, the MaxiScan can be connected to the OBD II port and all of the valuable diagnostic information can be downloaded, allowing vehicle owners to make accurate assessments and targeted repairs. With it’s hassle-free and simple interface, the MaxiScan makes quick work out of downloading key diagnostic information from your vehicle’s OBD II unit.
Small, powerful and light, the MaxiScan is a great gift or vital tool to be kept in a vehicle. When a “check engine” light or other dashboard indicator identifies a problem, the OBD II scanner can be plugged in to rapidly download the same information a qualified mechanic would be able to access with a much more expensive machine.
Some people find the connection sequence protocol a little tricky until they get the hang of it. The firmware on the MaxiScan cannot be updated or “flashed” from a computer, and the included CD-ROM is far slower and more cumbersome to use than a standard online search.
The INNOVA 3100 is a great mid-range home scanner for OBD II vehicles. It can quickly display VIN number, emissions readiness status and any identified DTC codes in both numerical and English format to allow vehicle owners to make quick and accurate diagnostic readings of their vehicle.

Our Top Rated OBD II (OBD2) Scanners
What Is A OBD II (OBD2) Scanner?
The first sensors were very crude, little more than a wire and a lamp that lit up when there was a problem. Known as an “idiot light”, these indicators were useful in telling drivers and vehicle operators that a problem existed, but were far too simplistic to pinpoint the cause of the difficulty. Once the On-Board Diagnostic (OBD) standards were updated in 1996 to become known as OBD II or OBD2, every vehicle manufactured in the United States became required to have an OBD unit installed.
Many people like to think of the OBD II unit as the “black box” of their cars. It contains a running log of operations, including temperature and fuel readings, speed, direction and location logs, as well as testing for emission leaks and levels. An OBD II scanner is a handheld device that plugs into your vehicle’s OBD II unit and instantly downloads all of the latest logs, readouts and recorded information about the operation of your car.
Problems are identified by Diagnostic Trouble Codes (DTC), which the scanner can translate into English or can be used to look-up more information in reference materials. With an OBD II scanner, any vehicle owner or operator can make periodic check-ups on the health and operation of their vehicle, and rapidly identify and resolve problems as they arise.
With a convenient handheld scanner, anyone at home can now plug into their vehicle’s OBD II unit and rapidly identify and diagnose problems. OBD II systems are now used to monitor vehicle emissions, and many states today rely on feedback from OBD II during inspections to ensure compliance with emission regulations.
What Are The Advantages Of Owning A OBD II (OBD2) Scanner?
It is a function of cars that over time different pieces or systems in the car begin to wear out, malfunction or break. Today’s advanced vehicles are loaded with sensors that can rapidly identify problems, but are often restricted to little more than illuminating a “check engine” light on the dashboard. With an OBD II scanner, anyone can quickly plug into the OBD II unit, download the sensor information, and accurately identify the problem.
Many dealerships and service stations charge $100 or more to perform the same task that a home OBD II scanner can do in mere minutes. Many vehicle owners find that some repairs and fixes are simple and easy to do themselves once they’ve confidently identified the source of the problem, saving them hundreds, if not thousands, of dollars in fees to dealerships or garages.
What Are The Different Types Of OBD II (OBD2) Scanners?
Federal law and industry standards mean that pretty much all OBD II units in modern vehicles are interoperable. While all OBD II scanners can connect and download information from the OBD II unit, some scanners simply display a DTC code which must be researched separately while other more advanced models explain and identify the problem immediately. Some advanced models can be connected to computers to download, save or further analyze data, or to provide firmware updates to the scanner itself.
All OBD II scanners can download data from the OBD II unit in the vehicle but some scanners can also display and record data in real-time, critically essential for some tuning and adjustment jobs. OBD II scanners work with every vehicle made in America after 1996 and with most modern vehicles made in Europe and Asia.
Considerations for Choosing the Best OBD II (OBD2) Scanners
The difference between a bottom line Scanner at $50 and a cutting edge scanner at over $2000 is the kind of codes which they read and analyze. Basic scanners only diagnose the “basic on-board codes”(OBD), while there are professional Scanners assessing many more aspects of the engine performance. They can read data about the brakes anti-lock mechanism, pressure of the tires or check the safety of the airbag system and many more.
After deciding on the kind of scanner you want to buy in your search on the internet you should answer the following questions:
Information and Display
Some home scanners do little more than show you the Diagnostic Trouble Code and not much else, while other scanners give you rich feedback about the status and condition of your vehicle.
Battery and Power
While all OBD II scanners can be powered via the vehicle’s on-board systems, many OBD II scanners contain a battery back-up function for offline use.
All OBD II scanners will download the standard set of data, including emission readings and DTC codes. Other scanners can show real-time functioning of the vehicle while the motor is engaged, allowing vehicle owners to make adjustments and check vital system read-outs during operation.
Many of today’s OBD II scanners can connect via cable to a computer, allowing for better visual displays of important diagnostic information as well as greater information about the cause and remedy for any ongoing problems.
Vehicle owners and operators know that it can be very frustrating and time-consuming to deal with potentially serious engine, ABS and operating warning lights and indicators. A big problem, if left untreated, could lead to a serious malfunction, but some warning lights only identify small problems and can be left ignored.
After careful consideration, the Actron CP9580A AutoScanner is our pick for the best all-around home OBD II scanner. With a multitude of diagnostic functions, including real-time analysis of motor and emissions functions, the Actron gives any vehicle owner a powerful tool to measure and repair vital operating systems.
