Enter an OBD2 scanner. This type of car scanner is crucial for understanding, maintaining and repairing modernistic vehicles. DIY types or anyone who wants to know what's happening inside their car -- and perhaps relieve a few bucks -- can benefit from an OBD2 reader and a basic understanding of what to do about certain error codes.

We encourage adding an OBD2 diagnostic scanner to your car diagnostic tool kit, but information technology tin be intimidating to wade through the best OBD2 scanners on the market, or to (hopefully) find the correct 1. There are hundreds of different OBD2 scanner options out there in auto parts stores, discount stores and at the far fringes of the net, with prices varying by thousands of dollars. Many are fantabulous, boasting useful feature afterward characteristic, regardless of price. Many are junk, with no legitimate product back up.

This list includes the best OBD2 scanner tool for every purpose and buyer, and information technology's updated periodically. Continue reading for an overview of how scanners work, what they tin can practice, our methodology for choosing them, key things to consider before ownership an OBD2 scanner and some pro tips.

OBD2 car scanners 101

If this "onboard diagnostics" stuff sounds intimidating, the nuts are actually fairly simple. Information technology started in the 1990s, when the US government mandated that all vehicles offset with the 1996 model yr be equipped with a standard self-diagnostic system called OBD2 (for onboard diagnostics, generation 2), primarily to monitor emissions control systems. Since and so, OBD2 has grown ever more sophisticated, monitoring ever more than systems, but the process remains the same. When OBD2 records a problem, it creates a fault or diagnostic problem code, then lights a alert on the vehicle dash (ofttimes that ubiquitous cheque engine light).

Fundamentally, an ODB2 scan tool reads and reports those trouble codes. Information technology plugs into the car's diagnostic cake, often chosen the OBD2 port -- an easy-to-identify, trapezoid-shaped female connector, noted in the owner's transmission and typically located under the nuance or near the steering cavalcade. Then it scans the OBD2 system to observe the faults or trouble codes.

Now, those codes are in fact codes, or v-place alphanumeric designations. Code P0420, for example, ways the catalytic converter is not operating properly. The most rudimentary OBD2 scanners still simply report the mistake code and you will have to check a reference manual or head for the internet to learn what P0420 means. But in 2020, the correct, still modestly priced OBD2 scanner will tell you what the code definition is in English (or multiple languages) without having to look information technology up.

The world of onboard diagnostics isn't too confusing with an OBD2 scanner.

Autel

All OBD2 scanners should be able to clear the code, though the bank check engine low-cal volition probable flash again inside a few miles if the bodily problem generating the code hasn't been fixed. And there are a lot of codes -- upwards of 5,000 and more all the fourth dimension, according to experts. Roughly 60% of those check engine codes are generic or universal, pregnant they're the same for all vehicles. P0420 ways "catalytic converter not operating properly" no affair the make or vehicle. So there are a few m more codes specific to the vehicle manufacturer (such every bit Chevy, Ford or Toyota and just Chevy, Ford or Toyota). A better OBD2 lawmaking reader will read the manufacturer codes, too, and explicate those in English.

There'south much more a good OBD2 scanner can do with the data in your OBD2 organization. Most will confirm the vehicle's VIN and show yous a Freeze Frame, or a rundown of key data points in the motorcar at the moment the check engine trouble code was triggered, to help pinpoint what caused the problem. Nearly volition report Live Data -- a potentially long list of data points like fluid temperatures, engine speed and load, fuel injection and spark rate, sensor operation and then on while the car is running. It's like the total fix of gauges virtually auto model types no longer accept and then some, and another valuable diagnostic tool.

Many OBD2 scanners volition conduct a simulated smog examination, checking the same things a service shop will bank check before information technology signs off on a smog document -- and give you a good idea if the car will pass or fail in its electric current condition. Some OBD2 scan tools allow you to evaluate the battery, alternator and ABS system. They'll relieve or impress reports with potential causes and possible repairs. The best tin can send commands to a car'south individual control modules and even plough them off and on. They let you make finite adjustments that the vehicle manufacturer allows in its control software and calibrate the tire pressure monitor system, or TPMS.

A good OBD2 scan tool can let y'all evaluate a auto's bombardment, alternator and ABS organisation.

OBD2 scanners are less expensive than ever, but competition makes the supply side of the market place wilder than e'er. Anyone who has carefully shopped for a mattress volition understand. In that location's a handful of established players, a agglomeration of upstarts and a vast surface area of racket. Even the respected companies will build substantially identical scanners with different model numbers and insignificant appearance changes to sell through different retailers (sometimes at dissimilar prices). Differences are sometimes hard to discern.

Depending on where you live and what y'all drive, a decent OBD2 scanner can pay for itself in relatively short guild, if only through the fuel and time saved by avoiding trips to the local auto parts store for a free lawmaking read. OBD2 code readers don't have to be expensive, but every car hobbyist or do-it-yourselfer should probably have one in the tool kit.

Two things to know before you buy an OBD2 scanner

i.Its primary purpose: What do y'all program to do with an OBD2 scan tool? If you merely want to know what that cheque engine idiot low-cal in the dash is telling yous, or you desire to independently evaluate what a repair store is reporting and perchance plow the low-cal off if it'south lit for something like a loose gas cap or a replaced EGR valve, you don't demand to spend much. Some $lx-$80 will get y'all where you desire to get, reliably and repeatedly. Fifty-fifty when the problem is solved, a basic OBD2 scanner remains a valuable tool if you or someone you know is looking for an cheap used auto.

If, on the other hand, you're an automotive enthusiast, a frequent do-it-yourself person or the friend nonenthusiasts come to for car advice, it's certainly worth spending more. More expensive scanners can take broader make and model coverage. An OBD2 code reader with the right features will help yous wait deeper into a motorcar's control systems, troubleshoot problems and settle on appropriate repairs. A ameliorate one tin help you analyze vehicle functioning, optimize efficiency and better understand how a vehicle works.

Consumer-priced scanners today do things that were reserved for $5,000 pro-grade scanners just a couple of years ago. The all-time are good enough that, if you intend to make money fixing cars, you lot could utilize them to get started. Eventually, though, you're probably going to demand ane of those expensive pro-grade models.

Dropping big bucks on an OBD2 scan tool isn't necessary if you lot're but reading and immigration error codes from time to time.

Autel

2. Which blazon works for you lot:Across the price spectrum, there are basically 2 types of OBD2 scanner. The dedicated hand-held scan tool is a self-contained device that plugs into the OBD2 port via cable (preferably long enough to reach from inside the auto to the engine bay) and does its job. Information technology has its ain screen, buttons, software and computer scrap.

The second type is a Bluetooth OBD2 scanner, known in the trade equally a Bluetooth dongle. This type is usually a fairly small, plastic device that plugs into the OBD2 port and then connects to a smartphone or tablet via Bluetooth. Its job is to wirelessly transmit data from the vehicle's OBD2 system to the phone, where that data is processed and presented past the dongle manufacturer's control app. With a Bluetooth OBD2 scanner, the quality of its manufacturer's software is paramount.

The master advantage of the Bluetooth device, if it isn't obvious: lower cost. Why pay for a screen and calculator bit when your smartphone already has those? A Bluetooth OBD2 code reader dongle uses those components on your phone, where the screen and the chip are probably much higher quality than you lot need for this task.

If the typical toll advantage in a Bluetooth OBD2 scanner sounds like a no-brainer, you should consider the more subtle bug. Dedicated scanners are in important respects more efficient to use and if y'all use the code reader regularly to diagnose check engine lights, or for longer sessions, speed and simplicity matter. With a self-independent scanner, you never have to worry about the quality of the Bluetooth connexion, your phone accuse or the force of your Wi-Fi or cellular point (the typical Bluetooth OBD2 scanner relies on admission to internet databases). You won't exist interrupted past incoming calls or notifications while you're using it. A expert dedicated scanner is more impact-impervious than a smartphone and drops are probably inevitable. What happens if your $1,000 phone falls in the engine bay and lands on the transaxle case, or gets wedged between a manifold and the engine block? Many Bluetooth scanners want to sell yous upgrade subscriptions and some of the apps have ads.

A dedicated OBD2 scanner in many respects is more than efficient to apply than a Bluetooth smartphone dongle.

Innova

You tin can go a solid, dedicated OBD2 scan tool for $100 or less, so the choice isn't as obvious as it might beginning appear. Information technology probably goes back to the commencement thing you need to know when buying an OBD2 scanner: your primary purpose for doing so. And maybe how oft you plan to use it.

Pro tips

The great majority of OBD2 scanners sold today will work on the dandy majority of vehicles built for model twelvemonth 1996 and beyond. All the same for fairly arcane reasons, there are exceptions to this assumption of universal application (a few companies still build scanners for specific makes). Most reputable browse tool manufacturers have application checkers on their websites, so play it condom. When you call back you know what scanner you lot desire, check to ensure that it volition work on cars you might regularly want to use information technology on. And if y'all programme to purchase a Bluetooth-based scanner, there's some other potentially embarrassing error. The command apps that connect with the OBD2 dongle are specific to the operating organization on the telephone, tablet or PC that'south going to run the app. Some manufacturers have an app for Android or Apple tree, but not for other OSes, much less for Windows devices. Ostend that there'south an app that will work on your device.

There'southward 1 more discussion of caution to note here. With some OBD2 scanners, some of the features or commands may non work on every brand or model of motorcar. This is largely a function of how the automakers build their command architecture or operating software. Some brands are but more than particular nearly what they'll let people run into and who they'll let see it. This applies particularly with scanners that let bidirectional control or adjustments within the vehicle's command software. As a dominion of thumb, US automakers generally allow the most access. College-end European brands let the to the lowest degree. Once more, you lot can sometimes larn something using the awarding checker on manufacturer websites. Often you can find the OBD2 scanner'southward operating manual online, so wait at that, too.

An OBD2 scanner is a valuable tool to assistance figure out what might be wrong with a machine and help become it fixed.

Innova

An OBD2 scanner is primarily intended to help figure out what might be wrong with a vehicle and and so help become it fixed. It tin reset certain parameters once the repairs are achieved. More capable scanners tin can make finite adjustments in certain vehicle systems. An OBD2 scanner is not a wink programmer -- a device that can really rewrite the carmaker's control code in search of more horsepower from the engine or dissimilar transmission shift points. Wink programmers are a thing, but they're a different brute entirely and typically auto-brand specific.

Finally, when it comes to OBD2 scanners, don't underestimate the value of production support. Even the virtually confident do-it-yourself folk will have questions about what the lawmaking reader might be telling them, or something that doesn't seem to exist working every bit information technology should. Across limitations noted in the list, the manufacturers of our all-time scanners should be able to provide answers to your questions and in reasonably short order.

Production support includes software updates. The reputable brands update their OBD2 scanner software regularly -- at to the lowest degree once a twelvemonth -- and then stay on top of it. The updates are commonly like shooting fish in a barrel to install, from a PC or over the air.
