Guide to Buying the Best OBD2 Scanners

Making the right purchase is important as it is rare for an OBD2 scanner to be updated. It is why some of the best products on the market are actually future-proof as they can last for years. Most of them can also be updated on their manufacturer’s website. The following criteria might still need to be considered when making a purchase.

Ease of use

One of the main concerns new users have is with ease of use. It is actually easy to understand why, as many drivers can associate diagnostic car scan tools with what they see at their mechanics’. But things can be different today.

From a few simple buttons to programmable controls, users should be able to find the easiest ways to deal with their car’s codes as there are many great designs to consider. The older the car, the more diagnostic tests might need to be run to deal with the various issues which might appear, from Check Engine warnings to ABS errors.

Connectivity options are mainly wired or wireless, if the scanner is actually made to send out data to a computer or a smartphone. Some of the newest scanners come with included Bluetooth connectivity which allows drivers of all ages to set their own standards when it comes to data transfer. This is best seen when this data is interpreted with an app that users choose, as many scanners are compatible with the high number of mobile apps on offer.

Types of codes

Scanners can read different types of codes. Some of them might actually be general codes, which are the Check Engine codes, specific to what most cars can go through.

Another important aspect to consider is personal preference. In some cases, drivers prefer to have a built-in screen which eliminates the need for adding a smartphone and complicating the process even further. In those cases, it is important to find the right display as they are as modern as many users hop for at the moment.

Customization options

Customization options are very limited on OBD2 scanners. Most of them are made to be user-friendly and not aimed at the professional. But in some cases, there are exceptions which can come in the form of volume control of Fn buttons which can be attributed to a certain action.

Users who like to get technical and who have a hands-on approach to gadgets are usually those who are set to do their best when it comes to customization. However, extra customization is generally added in premium products, which are actually suitable for mechanics.
