Best OBD2 Scanner in 2019 for your car problems!

With the advent of technologies designed to make life easier, diagnostic tools for cars have become more. Check our reviews of the best OBD2 scanners!

Automobiles operate on a delicate balance, and monitoring the correct running of an automobile is important in discovering, addressing and preventing faults which could lead to accidents. This need is filled by the best automotive scanners.

Automotive scanners are “electronic tools used to interface with, diagnose and reprogram vehicle modules”. This is a fancy way of saying that the best automotive scanners work with the vehicle to tell you when there is a fault, what can be done about that fault and sometimes even fix the fault.

OBD2 Scanner Buying Guide

Before choosing a scanning device, it should be clear what type would perform the needed function-a basic code reader or a more high-end scan tool, bearing in mind that the basic tools have the most compatibility issues and do not have the programming to cover more sophisticated protocols like an high-end device would.

OBD2 enabled vehicles use at least one of the following protocols: J1850 PWM, J1850 VPW, ISO 9141-2, ISO 14230-4 (KWP2000) and CAN-BUS (J1939 & ISO15765-4).

Users are advised to check the vehicle protocols before making a choice of OBD2 scanner to buy to make sure that it is compatible with the desired device and to determine whether a basic code reader would cover the functionality or a high-end device would be more appropriate. This protocol is provided on a label under the vehicle’s hood and in other strategic positions in the car. It can also be accessed on the Internet by searching for the vehicle specifications on the OBD2 scanner manufacturer’s database.

A basic understanding of the above explanation is enough to help you narrow your choice to the best, just as we have in the reviews below. However, you must also take into consideration the necessary market buying considerations, which include design, appearance, durability, customer support and even price. The best ODD2 scanners contain the perfect blend of functionality and affordability.

What Are OBD2 Scanners?

On-Board Diagnostics (OBD) is a self-diagnostics system formulated by the California Air Resources Board (CARB) according to specifications laid down by the American Society of Automotive Engineers (SAE). This system works by using a car’s onboard computer hooked up to a standardized, external self-diagnostics system to report on the state of the vehicle’s mechanics and detect faults when they arise.

The earliest OBD systems (designated OBD1) had to be adapted to suit different car manufacturers. The newer systems have been upgraded to use the same communication protocols, code designations and connectors for all the car manufacturers.

Thus, the best OBD2 scanner can provide the desired data required across all makes and models of cars produced in and after 1996, making it more universal and easier to use.

This eliminates unnecessary waste of resources in the maintenance of vehicles of different types and streamlines the process of automotive diagnostics so that even an inexperienced user who wants the DIY experience can undertake diagnostics successfully with the use of the best OBD2 scanner.

Classes Of OBD2 Scanners

The difference in the class creates a distinctive categorization which eventually helps your choice more straight forward. OBD2 scanners can be broadly divided into two categories:

Code readers can read and clear codes from any OBD2 enabled vehicle. They are limited in this function in that after reading the faulty vehicle codes, an experienced mechanic or a manual would still be needed to interpret the codes and proffer solutions to the errors. They just provide basic information.

Scan tools are more varied in function, and thus more expensive. The user is given access to a wide range of features including manufacturer-specific codes, a database of information to draw upon when there are faults and specific fixes for code errors. Due to this comprehensive function, scan tools are the best diagnostic tool able to be used even by an inexperienced vehicle owner with ease.

How Do OBD2 Scanners Work?

OBD2 scanners are equipped with several features that are determined by what class they belong to: scan tools or basic code readers. Either way, their interaction with the vehicle is accomplished in the same way.

OBD2 enabled vehicles to have ports, activation centers and sensors in strategic positions all over the interior of the car. This enables them to monitor the proper functioning of the vehicle and control engine functions through the onboard computer, taking regular readings of both normal and abnormal activities of the vehicle.

This it does by taking regular readings of different systems in the car including the engine, chassis, frame and other parts of the car. These readings are then charted against a pre-determined and standardized set of codes that represent different areas of the vehicle’s functionality, and abnormalities are easily spotted and reported as error codes.

All the information gathered is stored in the system and can be assessed by attaching a computer or smart device to the port and downloading the codes. This makes it so easy to pinpoints faults and under what conditions the damage or malfunction occurred. It also makes implementing a specific solution easy, eliminating generalized hail-Mary fixes that might do more harm than good.

The best OBD2 scanners even have support hotlines that can provide technical help to car owners and mechanics, while others are equipped with comprehensive user manuals even in the form of interactive videos, which the user can access and follow the instructions step by step to repair the noticed fault.

Both professional mechanics and DIY-enthusiasts could find an OBD scanner invaluable in their arsenal of tools, even though the expensive, high-end scanners could be unnecessary and too expensive.

More difficult fixes can be left to a professional or the needed step-by-step information for correcting the fault can be accessed on any available companion manual if it is provided.
