> Ultimate Guide to Buy a Best OBD2 Scanner <

Here I will explain to you why it is beneficial to buy a Scanner and guide you to choose the best Scanner which would fit your Budget.

OBD is generally divided into two categories;

  1. Code Readers
  2. Scan Tools

An OBD Code Reader may not have much of a difference from the scanner. A reader is an electronic device which when connected on the car computer memory allows the user to have access to certain information regarding the car function. This information may not be as elaborate but quite useful in the process of car repairs.

In most cases, OBD readers are functional with other accompanying accessories which may include external connections to a PC. Not all readers are the same and the experiences seen with each differ depending on the coding scope.

OBD scanners are no different given that they are also electronically oriented to be connected to the car computer memory to help with deciphering important information.

How different are readers from scanners?

Though these two tools may seem to perform almost the same functions, the OBD code readers are considered a little bit inferior and may not give more advanced data as the code readers.

In addition, the standard practice adopted in the making of the OBD scanners make them more universal tools rather than the readers which were rather manufacturer specific.

Readers or scanners, the purchase dilemma!

The decision of not to buy or top buy usually rests with the user.

Though code readers are relatively cheap, the scanners are usually considered better by most motorists given their scope of action. Buying a reader may limit the level of fault codes to be read.

If you ask me, the scanners are the best for any car owner because of the standard coding nature and so may be used over several; car brands.

Why buy OBD scanner?

Most people have read so much about the on board diagnostic tools and may have wondered what they do. In almost all modern vehicles, OBD scan tools are fitted to help with the cases of reducing emissions.

There are two categories of OBD commonly known in the market. These are;

  • OBD I
  • OBD II

Knowing which OBD to buy may just be the perfect opportunity if you are a motorist with an eye for safety. Though this may be important, most people may be quite oblivious of the diverse reasons why one needs this device fitted on the car engine.

Among the few places where one is able to find that information is from our site which has been the best place to get anything to do with OBD.

Welcome and read on!

What is the driving force for purchase?

To the chagrin of many motorists, OBD scan tool use has become part and parcel of their car use on a daily basis. Some of the major reasons why the OBD is purchased for fitting on vehicles may range from the following depending on where you are;

  • Avoidance of huge repair and time costs – in the past, the lack of something to detect when the car engine was having some fault would leads to enormous engine break downs. This would then be taken to the mechanic where the cost of repair alone would be skyrocketing.

In addition, motorists who visited these yards agree that the pay per hour method in most yards favored the mechanics that would spend hours on end, on something which would be done by the motorist. The OBD scan tool has solved this problem by alerting and giving the driver the specific information on the fault. Because of the do it yourself (DIY) approach of OBD, this problem can be solved by the driver or be taken to the mechanics.

  • Environmental protection – in countries like the United States and other European countries, it is the norm which has strong legal backing that these tools be fitted to reduce cases of dangerous fumes coming from faulty vehicle engines going into the environment. Buying this instrument is an act of conservation as well as patriotism.
  • Urgent cases arising from breaks of the former tools – as a motorist, it is imperative to check on the OBD scan tool and see if it is still in order. When that is not the case, having anew OBD tool may not be an option but a necessity.
  • Class and economic factors – rising cases of opulence and class society may drive one into a buying spree for particular vehicle parts and accessories. This is also due to the changing tastes which come with change in status.

These facts alone may not be the main reason for one to choose any given OBD scan tool. There are other functional reasons which make people choose particular tools. These are;

  • Efficiency – some OBD scan tools are known to cover diverse fault coding areas which can in turn make them desirable to the users. The ability of particular tool to give quick results for instance is usually on major driver to purchases.
  • Preferences – the choice and taste of the clients on the several tools in the market determine the urge to buy. One person may develop an attachment to a particular scan tool making it the best choice to purchase.
  • Nature of action – some OBD scan tools work through the remote basis which may be loved by a person and make him buy that tool.
  • Peer referrals – many are the times when one can end up buying an OBD scan tool merely due to the good word a friend threw fore it. In other instances, reviews may also drive one into buying a particular OBD scan tool.

Types of OBD scan tools

On board diagnostic scan tools have been coming in all shades and color since inception. While the advent of technology has always been at the epicenter, most of these are geared to help in the easy detection of the vehicle fault. The known OBD scan tools in use are;

1. The manual plug and play devices – they are in most cases specific in the user scope. They require an OBD user cable to plug to the DLC port to work more efficiently. They are hard to update and therefore quite rigid in accepting new car brands. The new versions have the ones with updatability through USB.
2. The wirelesses Bluetooth OBD scan tools – these are always internet based devices and work without the need to plug to the DLC. They connect to the car DLC port remotely when prodded and are quite fast. In most cases, they are updatable via the internet and may be used on diverse car brands. In some cases, these can also be in the form of mere applications.

The diversification in OBD can also be seen with some being seen to rely on the car engine for power and so are dependent devices. Most OBD I code readers are dependent on car battery.

While others are seen to be non reliant on the battery power and can work even when the engine is off. These are standalone devices, as is the case with most OBD II scanners.

The OBD scan tool generations OBD I and OBD II

The distinction in onboard diagnostics has been always in the form of generations.  There are two generations spanning the entire OBD period. Let’s look at them at a glance;

A). 1st generation readers, the OBD I

While the OBD I is known to be the older generation tool and was the precursor of the whole diagnostic system, its use has been dwindling with time because of the following;

  • It was generally manufacturer specific, covered few fault areas and so not industry friendly.
  • Some of the OBD I making companies were developing bad production practices to eliminate competition.
  • Most of the broken down tools would be hard to refuse or dump, causing a catastrophe on the environment, which was being avoided.

B). 2nd generation scanners, the OBD II

The OBD II has been the latest in the generation of scan tools and is in most cases referred to as the second generation scan. It has been a result of the most widespread industry consultation and regulation on the production of a standardized tool. Most of them are;

  • Not manufacturer specific, cover wider car fault areas and may work across the board
  • Made with the overall motoring industry in mind.
  • Most are made with updatable features and so used for longer.

Old vs. new – the two sides of OBD scans tools

OBD scan tools in the market span the OBD I and OBD II. Most of the OBD I tools are used in areas where the strict industry regulations have not been enforced. The most striking balance is that there has been a steady rise in the number of companies producing OBD scan tools, with most following the regulations set by the environmental protection agency (EPA) in the area in question.

Because of their meager coverage, they have been replaced with the OBD II devices over time. With the developments in the internet, the Bluetooth OBD scanners are taking over as the most preferred mode of vehicle engine fault scanning.

How to buy the best OBD scan tool

Because of the diversified nature, buying your best OBD scan tool cannot be that hard if you have the relevant information. In most cases, the information on the scan tools is in great supply on the several websites where they are stocked. It only requires one to compare the features and see if they fit with the needs of the vehicle.

Considering on the cost, online purchases can give you some of the best bargains because most of the shops do not charge for the rent spaces, which may not be with the brick and motor stores. In addition, the delivery period in most of these shops is quite fast

What to look for when buying OBD scan tools

There are certain things buyers look for when buying OBD scan tools, like in the choice one has to make on OBD readers and scanners, some of the most notable facts may be enumerated as follows;

  • The OBD brand – most people are in most cases attached to specific brands and that is what determiners their purchase decision. The manufacturer can also determine the warranty and the after sales services you are likely to enjoy.
  • Price – depending on the budget, it is imperative to choose an OBD scan tool which fits within your budget.
  • Design and quality – while some OBD scanners may just be too bulky, the choice of the right design may be the ice breaker. these are usually seen in the various feature it possess based on the user manual

Other factors to consider when buying OBD scan tools

With the former considerations, other likely factors to consider may be the following;

  • The car in question – while this may not be so much a factor in the current generation, it was previously with manufacturer specific OBD scan tools. The knowledge whether it was compliant used to play a vital role.
  • Durability – buying a scan tool which can serve for long ids the dream of any OBD scan tool user, looking at the material used in making the casing and whether it is weather proof may help in this area.
  • Presence of other relevant supporting accessories – buying an OBD with better supporting accessories like the user guide and the code translation manual may also help the user in a great way.

While all these considerations may be golden, the most important consideration is the use of your own discretion when making any OBD purchase decision.


The search for the best OBD2 scan tools may in most cases seem to be an elusive one. This is additionally made worse with the tendency of buyers to fall for gadgets without having taken time to look at how they work on the user manual.

Depending on which tool appeals to you, these top 10 best OBD2 scanners for 2016 will be your best catch. There are however others which may not make this cut yet so efficient, cheaper and may need your scrutiny.
