Your need-to-know when choosing the best diagnostic scanner

Let us have a bird’s eye view of the characteristics that earned them a place in that said list. Below you will find the factors that we considered and spent countless hours looking at obd2 scanner reviews and research to arrive at our top ten.

Types of OBD2 Scanners

There are primarily two types of engine code reader that are available in terms of connection type. The most common is the wired type and it connects to the OBD2 port via a wire to the scanner itself. The other one that is increasing in popularity is the one that uses a wireless protocol, usually Bluetooth, and simply connects to your smartphone via a companion app. Let us talk about them in further detail below. Types of OBD2 Scanners: image


This type of OBD2 vehicle code reader is usually an auto diagnosis scanner and is characterized by a somewhat bulky screen and connects via a wire to the OBD2 port in your car. The data from the car’s engine is processed by the handheld unit and works with no other devices needed, such as a smartphone or a tablet. The main advantage of a wired scanner is that it works on a stand-alone mode and is generally more robust and durable in construction. It is not uncommon to find ones that are both encased in rubber and tough ABS plastic, making them immune to rough handling.


These types of OBD2 scanners are increasingly becoming popular due to their cheaper price and the practicality that they offer. The best obd2 bluetooth scanners usually can fit in the palm of your hand, and you can literally forget about them when you attach them to the port. The caveat is that these will only work when connected to a mobile device, such as smartphones or tablets. These devices usually connect via Wifi or Bluetooth. Another appeal of this type of auto code reader is that you will not even notice it was there, having no wires that stick out to speak of. It is however better to get the ones connecting via Bluetooth as they have more range and yet does not consume more battery life.

Key Features that a good obd2 scanner must have

Because there are a lot of OBDII scanners out there claiming to be the best, here is a handy checklist of what needs to be in a car diagnostic tool before it can be considered a high-quality product. These are the most basic features and functionality that any diagnostics scanner should have.


While this may sound funny, we are dead serious about scanners that are lacking in what they can actually scan. This is critical because some engine diagnostic tool have a limited range on what they can read from the car’s computer. When choosing a scanner, make sure that it can read pertinent data from the various sensors in your vehicle. Take the time to read up on what a particular scanner can read as the data that an obd-ii scanner can vary from engine to engine. Check if the product can only read basic trouble codes or if it can read and diagnose advanced codes.

Access to engine settings

Some of the best car diagnostic tool available will have the ability to change settings in your vehicle that can only be set at the factory. The scanner you choose should have access to different settings and even change or tweak them. Today, any scanner that just shows you trouble codes without access to clearing them or tweaking the setting is seriously lacking in features. Make sure to avoid this kind of car computer reader. One of the ways you can do so would be to look at the particular automotive code reader review to avoid any costly mistakes.

User-friendly interface

A good quality professional car diagnostic tool will not just show you codes, but also include information as to what the codes are about and the really good ones will also present troubleshooting guides or show you how it can be cleared. Unfortunately, most scanners can only do the simplest, which is to just show you the codes and nothing else. This becomes one of the requirements for choosing the best obd2 scanner for the money. This also covers those that have large LCD screens for easy visibility, especially when working under direct sunlight or bright shop lights.

Provided Information

The best scanning tools for cars should clear things up for the mechanic and not add to the confusion. There are a lot of products floating around the marketplaces that make buyers question, which obd2 scanner should I buy? Look for the advanced scanners that will not just spit out trouble codes that need online research to decipher, but those that interpret them into immediately usable information.


While the OBD2 port is the only way to access the engine’s computer to read its codes, there are two ways to connect from there to the scanner. Wired and wireless options are two ways to read the data coming from the scanners. For wireless options, there are Wifi and bluetooth obd2 code readers where the module is plugged into the port and then just broadcasts the information to a companion app on a mobile device. Wired scanners connect to the port and the data is fed into a handheld device and operated from there. The wired OBD2 scanners are often stand-alone, meaning they will operate without the need for a smartphone or a separate device. It is important to note though that wired devices have an advantage where they do not suffer from dropped connections or interference that may plague wireless devices.

What to look for when choosing the top obd2 scanner


This goes without saying that in getting the best scan tool, look for one that will no just let you check and view engine codes, but also let you clear them. The features will mean a higher price for sure, but if you choose the right set for your needs, the device will more than pay for itself in the long run. This will also extend to the actual chassis of the device. Some are simply plastic casings that easily break in the rough and tumble garage environment, and others take extra steps and materials to make the device more robust. Choose a fully-featured device that can physically hold up well to get the best price to performance ratio.


Connectivity-wise, nothing beats the convenience of a wireless setup, you can go around, under, or even over the engine while it is being diagnosed with an obd2 scanner bluetooth-enabled device. Getting rid of the wires allows an extra dimension to car repair and it is always a plus. However, even the best bluetooth obd2 scanner cannot work without a smartphone or a tablet and this is where wired scanners come in. Wired scanners are stand-alone and will work by themselves.

Value for money

Price may be relative but not when it comes to the best cheap obd2 scanner, with this device, the price should correspond with what the feature set is and what it can offer in terms of benefits. This is why a basic obd2 live data scanner will cost significantly less than an advanced unit that can clear and reset codes. Your preference will play a part in this, as well as the features you need. Weigh in on the features that you need to maximize the amount that you pay for the device.
