Best OBD2 Scanner Reviews 2017 – 2018

This Automotive Scan Tools Buying Guide covers everything you need to know about buying your diagnostic scanning tools for cars. Many cars in this day and age come complete not only with sophisticated car alarm systems that automate locking and when they’re being stolen; they also come with diagnostic computers of sorts that many modern mechanics and enthusiasts of DIY home repair benefit from. It’s like an airplane black box, only this time it’s for your hot rod.

Your OBD2 scanner or automatic scan tool should be able to test the car’s systems, diagnose its faults, and reprogram control modules by itself rather than having a mechanic or the car owner do everything by himself manually. This is incredibly handy because it automates vehicle maintenance or at least makes it easier for car owners and their mechanics to do maintenance on car. It can even save you thousands on repair bills.

OBD2 Scanner Buying Guide

Mechanics can depend on the electronic device or do a manual override to check out the problem themselves. It’s a welcome option that streamlines maintenance, upkeep, tune-ups, and even overhauls the same way your GPS has optimized driving to unfamiliar places without a map. It’s another piece of technology that has made your life easier, like the microwave, the Internet, and your smartphone.

With that in mind, when buying an Actron scanner or some other automotive scanner type, you should know all about these wonder machines. Back in the day, you need tune-ups on cars to keep them running as smoothly as possible. Thanks to this device, you can make your car self-regulating because it assists in monitoring the car, from fuel mix adjustments on the engine to helping deal with your ignition and fuel injector maintenance. It’s essentially a tune-up in a box that turns your car into a self-regulating machine. 

What are Automotive Scan Tools?

Automotive scan tools ensure that your car runs at optimum performance because it adjusts things that your mechanic checks up on every tune-up. Check the instruction manual to check how well every part of your car is functioning. This guide also helps you interpret error codes when the emergency malfunction indicator lamp (MIL) lights up. An automotive scanner has access to various aspects and parts of your car so that it’s easier to fix it when it’s malfunctioning.

An OBD Scanner allows you to know post-haste when something is wrong. At any rate, the main formats for scanners follow Data Link Connector (DLC) Bi-Directional Computers, Diagnostic Trouble Codes (DTC) Code Readers, and (of course) On Board Diagnostic (OBD) Feeds. In particular, the OBD covers info about the performance of your car since that’s what it specifically checks on. It’s the type of device that can vary in shape and application.

You have your scanners that are software programs linked directly from a desktop or laptop to analyze car performance. There are also handheld diagnostic tools or plug-in readers you have to put right into your vehicle itself to give their diagnosis. All of these tools are supposed to analyze the performance of your car and interpret error codes so that you know what needs fixing. That’s what a quality obd ii scanner is capable of doing, essentially.

They’re the ones that issue important readouts whenever your car’s warning light comes on. This way, you can save money on mechanics having to play detective to see what’s wrong with your car, even if it’s something as simple as interpreting whether that clunking noise is something benign or potentially harmful (and expensive). There are even sophisticated devices out there that offer advice on how to fix your car problems like a helpful online wiki. 

Watch this in-depth 30-minute clip for the full understanding of how to use OBD-II Scan Tool. Simply cannot have a better resource than this:

The OBD Standard

There’s an increase in car tech that’s led to developers creating much more increasingly sophisticated sensors and monitors for automobiles. It’s come to the point where the days of people relying on sound vehicular maintenance as an absolute necessity are now long gone. That’s not to say no one ever bothers with tune-ups any longer. They’re just not the sole means of finding out car problems.

In fact, many OBDs like the Autel Maxidas DS708 can assist mechanics in going about their tune-up jobs since the scanners scan the problems for them and gives them enough clues on what to fix and what’s working perfectly when it comes to your vehicle. Speaking of which, the OBD stands for On Board Diagnostics. It came about exactly because when automotive scanners were first introduced, there was a different device for every vehicle make and model. An actual standard was required, and OBD was that standard.

Thanks to OBD, mechanics now have a universal standard to follow and have fewer troubles when it comes to taking care of one scanner to another since every one of them follows these principles that make up each and every device. It came about in 1996; it was agreed upon by manufacturers that OBD systems would comply with the same operation code to get rid of this dilemma of differing standalone scanners every time. An Actron CP9125 OBD is no different from an INNOVA 3160 Tool, thanks to this standard.

It makes the learning curve of dealing with different makes and models of scanners less of a hassle to go through when everything is said and done. This also allowed mechanics to work on a wider car range as well. The OBD II standard further ensured that every last manufacturer worked on the same system.

So the best OBD2 Scanners are:

To Summarize

Over time, OBDs became much cheaper and affordable for most car owners, so more sophisticated OBDs were made to cater to this wider audience of vehicle owners. They’re now currently designed for use of not only professional mechanics but also amateurs and car owners who wish to go the DIY route when maintaining their cars. Even non-trained owners of cars with OBDs can do tune-ups easier, or at the very least help out their designated mechanics.

Whether it’s the Innova 3100 or the Bluetooth OBD2, the functionality and quality of an OBD depends on how much money you invest in it and how expensive it is. Meanwhile, the lower-end scanners simply list “trouble codes” for you or the mechanic to interpret. The costlier and more complex models, on the other hand, list out the problems outright and recommend actual solutions. They also do monitor running and I/M (Inspection Maintenance) Procedures.

The market for automotive scan tools is wide and expansive. You can pick between the six ones up the review section of this article of you can find others that are a better fit for your budget. However, as a rule of thumb, the best ones to purchase (like the OBDs being reviewed here) depend on the amount of money you have in your budget for them and the depth of information you require from them.

If you’re merely searching for trouble codes, these scanners are quite affordable. When searching for an excellent car scan tool or the best obd2 scanner, they don’t only give you out trouble codes. They’re on-board computers that outright outline in an in-depth fashion what needs to be done, what’s the cause of the problem, how you can go about avoiding the issues in the future, and complex diagnostic analysis plus I/M information. They deliver all the data that’s essential in maintaining, tuning up, or outright overhauling your car. Just remember that extra info comes at a steep price.
