What to Look for in an OBD2 Scanner?

What to Look for in an OBD2 Scanner

There is a wide array of these models in the market coming in different shapes, sizes, and prices. Each of these scanners has a range of features and functions, depending on their price.

Although a more expensive scanner will have more features and a wider range of operations that are offered with the purchase of one, there are many important functions and facilities that are included in a good OBD2 scanner under $50.

First of all, we are to consider what a scanner allows us to do with the codes it reads from a vehicle’s on-board diagnostics and other core functions.

The scanners usually have no trouble connecting with vehicles of almost every build and model, since the OBD2 is a standardized system.

Depending on the model of scanner, here are some of the functions that we may be offered by an OBD2 Scanner under $50:

Software Compatibility

As with most electronic devices and scanning tools, OBD2 scanners also require software applications to run and perform effectively.

It is wise to have a good idea of the manufacturing details of the desired scanner and its software compatibility before purchasing it.

Personal research and customer reviews from reliable online sites will always help in finding out the compatibility options before finalizing the purchase.

Buying a scanner without checking its software complicity is likely to be very useless and a waste of money.

Physical Aspects

After all the internal functions, we need to consider our preferences in the physical aspects of a scanner and the user interface related inclinations we may have.

Most of the scanners that we may find in this price range come in different shapes, sizes, and interfaces.

A large, user-friendly display is always the best choice. It should have a bright display with specified buttons for designated functions.

For maximum ease of use, the scanner should have a simple interface that the user is comfortable with.

Also, it should have a small and compact design for portability. The handling gets easier if there are grip notches at the sides. As for the cable, longer ones are always more preferable for providing mobility.

Lastly, the purchased scanner must come along with all the necessary cables, adapters, and, most importantly, a detailed user manual.

Customer Support Mechanisms

It is often very disappointing to invest in a product and not get the value for price or technical support when it is required. This is also the case with these scanning tools.

Hence, it is recommended that the purchase should be made from a trustable company and a manufacturer that provides full customer support and product warranty.

This will save the buyers a lot of hassle if they face any difficulties with handling the product or need any help while repairing or replacing the scanner.

Available Updates

Similar to any other electronic operating system, OBD2 scanners also need the latest software updates to ensure efficient performance and delivery.

This is also essential and important for detecting the right error codes and displaying the correct information on the scanner.

Hence, it is vital to check the available updates for the desired scanner and to make sure that the software updates are well-documented and running smoothly.

If the updates are documented poorly, the user will have a hard time interpreting the error codes from the display screen of the scanner.

For this, we must ensure that proper updates are still available for specific models and familiarize ourselves with how to install these updates.

Although all the features mentioned are standalone and some are exclusive to one another in different models, it is possible to find OBD2 scanners in the market that include most of these useful characteristics, and that too at quite a reasonable price.
