What is an OBD-II scanner?
Some of you might already be familiar with this important tech piece but for those who don’t, let me briefly describe it for you. OBD II stands for On board diagnostics and constitutes a standard system of computer network in your car or truck.
It is used for diagnosing (or more accurately, self diagnosing) any issues concerned with the automobile and reporting it to the user.
This revolutionary system was developed and implemented by the society of Automobile Engineers known as the SAE.
Now you might be wondering how OBD-II scanners are different from their predecessors, the OBD I scanners. In the latter the design and working was OEM–specific while their nest generation uses similar communication processes, connectors and code patterns.
This allows for a more extensive use of the equipment in automobiles of different makes and models i.e. automobiles produced after the year 1995 can be easily incorporated with these self diagnostic devices.
How to choose the right OBD II scanner?
By now, you might have gained some knowledge about OBD-II scanners and their functionality. Now let us look at all the different considerations to be taken into account while choosing an OBD II scanner.
The task of choosing an OBD II scanner would not be as easy as it seems. When setting out to buy one for yourselves you need to have precise knowledge on what your car wants.
As each car is unique and needs to be treated that way, choosing the right OBD II scanner is a somewhat hectic task.

What to look for when making the purchase
While setting out to purchase an OBD II scanner for your car, there are a few considerations you need to take care of. So here are some basic questions that you need to ask yourselves before making the purchase.
What level of functionality do you expect from your OBD-II Scanner?
Firstly make up your mind on what kind of a tool you really intend to have, whether you need a high end model or just a basic one.
The basic code reader is characterized by limited functionality. It is capable of a few things all of which are basically intended for notifying the user about an issue that needs to be diagnosed.
For those people who are a low on budget a basic code reader would be a good option.
The basic models suffers from an issue concerned with the compatibility i.e. not all car models can use these basic code readers.
Also don’t get me wrong, the basic model is also quite an effective tool and a possible life saver.
On the other hand, the high end models are more advanced and provide great confidence and safety for the driver. They are more compatible for extensive use and is loaded with features and functionalities such as:
- ABS and air bad control – The system can detect the anti lock breaking systems, air bags and some more functions of the car and is also capable of resetting them.
- On screen information – the diagnostic codes are displayed right on the screen providing a better user experience.
- Printability – the detected codes and subsequent results can be made into physical copies i.e. the information can be delivered to a printer if necessary.
- Live feed – All information regarding the working state of the automobile and its sensors are displayed in real-time. This provides the user with precise and updated information and anything out of the ordinary is simultaneously reported.
- Storage and data logging – The data and information are all stored safely in the sensor memory allowing it to be accessed anytime in the future. This data can be used in the identification of a particular car as well as assessing its past.
Is there any scope for upgrading the existing model?
Cheaper OBD II systems often provide no scope for any sort of upgrade. So it is often recommended that you go for high end models which might be a bit expensive at first but in the long run seems to be quite an acceptable bargain if the model can be updated in the future.
The importance of updating these diagnostic devices can be understood by considering the case of a smart phone. You would update apps on your phone to get better features and usability and in the same way you need to upgrade these systems as well to get more features and to be used with newer car models.
These updates may not be free always, so it is always advisable that you enquire about the costs well in advance.
Would a particular model of OBD-II system be compatible with your car?
OBD II systems are basically of five types based on the signal processing procedure. So you should always ensure that you would not face any compatibility issues when installing one of these types in your car.
There may be some products in the market advertised as cent percent compatible, but it is always safe to ensure the same before purchase.
What type of OBD-II scanner do you require?
- PC based scanners – There are PC based automatic scanners available in the market and they draw power from the PC to operate. They are effective systems for diagnosing as well as troubleshooting issues in your automobile.
- OBD II Bluetooth scanners – These systems works through your smart phones or tablets by making use of Bluetooth connectivity. This works even with computers and serves as an advanced scan tool that detects, notifies and troubleshoots any engine or sensor issues that your vehicle may face.
- The hand-held scanners – Handheld automatic scanning devices are used mainly by professionals and mechanics to detect and diagnose issues concerned with the engine, brakes or even the transmission systems of an automobile. They are more sturdy and advanced devices with better and more informative display of data. The system comes in a package and comprises of a power supply, a cable to transmit the power, an additional battery pack and so on.
