The history of the OBD scans tools

What is OBD?

The On-Board diagnostics known as OBD is used as a generic term that refers to the self-diagnostic and reporting capability of a vehicle. This performance offers the mechanic   and the user a direct access to information on the state of the engine health and it always encompasses various sub-systems inside the vehicle.

There are two known models of the OBD2 Tools in the market. While the OBD-I was essentially intended to alter and encourage automobile mechanics to align to certain reliable emission management systems that were to last throughout the vehicle’s usable life. It was found not to cover the car engine system in the most efficient of ways.

The new generation on board diagnostics, known as OBD-II this is often an improvement over OBD-I in every capacity and standardization. The  auto scanner diagnostic tool primarily offers three unique specifications embodied on the manner in which the diagnostic tools are built to give a clearly specified data scan. These specifications border on the electronic messaging format, electrical signaling protocols and a list of auto parameters to scan besides having the capacity to give very clear interpretation of the scanned data.

There are a number of standards used within the on board diagnostic system. One of such is the Environmental Protection Agency (EPA) standards.  The EPA was aimed at reducing motor vehicle emissions especially the trucks and cars. The EPA rules require the manufacturers to make cars that meet the strictest emissions standards.

Most of the OBD II scanners are EPA compliant if we dissect it against the former OBD I. whereas OBD-I tools could simply be used for emission management systems on cars that didn’t have any given standards, OBD-II provides a universal scrutiny and identification methodology to make sure that the car is working according to the Original instrumentation Manufacturer (OEM) standards.

Origin and evolution of OBD scan tools

The state of California had intent to combat the air pollution issues in the state. This led to the authorities to start requiring emission management systems on all 1966 model of cars. It was in 1968 that the federal government enforced these controls nationwide.

It was finally with the passage of the Clean Air Act of 1970 which was underpinned in the congress in the same year of 1970.the Environmental Protections Agency (EPA) of 1970 was established through this act. This started a series of emission standardization for emission which was meant to help in the maintenance of vehicles which has been in place for some time now.

Only electronically controlled systems OBD were found to meet these high end standards. Most Sensors help in changing the engine performance so as to produce the minimum potential of the engine to cause pollution. These sensors are additionally useful in providing early diagnostic help.

Since its origin in the early nineteen eighties, OBD has undergone varied levels of complex changes in terms of the number of diagnostic information it offers. The earlier models of OBD would merely indicate malfunctions illumination indicator light (MIL). These indicators are additionally marked as “the check engine light”. However some OBD scan tools of yonder wouldn’t give elaborate information on the character of the matter.

Modern OBD models use an identically quick digital communications port to produce timely and periodic data besides the manufacturer standardized series of diagnostic fault codes (DTCs). These are known to enable the mechanics and the drivers to spot malfunctions within a vehicle and organize for the appropriate remedies in a flash.

What is important for any driver or mechanic who wants to use these scan tools on his car is to know which car brand is in question. This is then bound to assist the user in making the best selection. However, having them has become a fundamental requirement in most emission regulated countries globally; it is just a matter of time before all countries adopt their use.

The OBD user assumptions, the red lights to look for

While the OBD scan tool is quite an important tool to have within your car, there seems to be an over indulgence on their importance. This has even made most users have the misconception that the OBD scan tool is a know it all tool. Far from it, the auto diagnostic tools suppliers covers so much within your car engine but it still has certain points to look for in case you develop a problem with your car.

Some of these areas may help you in expeditiously solving issues arising from your car showing the malfunction indicator light which in most cases can be persistent. They include;

1.Over-relying on the data-studies has shown wide gaps in the OBD data availability especially if the fault may have been caused by some gas issues. For instance, there could be a malfunction indicator light even after the coding process is complete. This usually presents a big challenge yet the problem could just be that some area within the gas tank is not fully closed.

2.Not conducting OBD periodic inspections– the benefits accrued by conducting inspections at intervals involving several drive circles has been emphasizes. While most drivers think that the scan process should be continuous, it is beneficial to allow the scanner pick enough data for you to act on. The periodic inspection also helps the driver be kept abreast with the going on within his car and thus avert any cases of engine breakdowns which may also result into spiraling costs of repair.

3.Avoiding visiting the mechanic– it is clear that in most scenarios, there are likelihoods that the driver may intend to cut on the overall costs of repair and so jump the process of seeking professional advice. This should not be the case. The mechanic still play an important role in helping detect certain faults that may be appearing on the OBD scan tool data display and not known to a non professional.

It is additionally clear that there are likely other car issues which are not related to the gas situation of the engine. These scenarios are not likely to be detected by the auto scanner diagnostic tool system which requires professional help.


Think of other automotive car effects-the presence of other additional failures not likely seen on the OBD scan tool is also another challenge which calls for visiting of someone qualified. For instance, it is not entirely final that all environmental issues will be sorted out with the presence of an OBD scan tool. Take the case of the usual OBD 4gas analysis which only identifies the emissions of CO2 and potassium. Environmental experts on car use may be of help here.

Cost assumptions– while the debate on the use of the OBD scan tool continues, cost remains one of its strengths. The pundits claim that it is the most cost effective method of conserving the environment as well as courting down on the car user cost.

The disparities which have been proven in different studies conducted in Germany and Britain have however proven this to be only true to some extent. While the Germans experience zero cost reduction with the use of an OBD scan tool, the Britons were noted to benefit a lot from the use of OBD scan tool. These factors could be attributed to the fact that the several diverse user policies adopted in different countries influence how much the OBD use will cost.

The OBD scan tool assumptions and theories will be important if the countries are to develop comprehensive user policies which may help determine the user scope and environmental policies. More input may still be needed from the stakeholders.

What is the best OBD tool for the car

The question of which on board diagnostic (OBD) scan tool suits the car has been one shrouded in mystery with lots of answers hanging. This is usually seen in people who are just getting introduced to the OBD use and may not have the best know how on which the most suitable tool to use is.

The choice of which OBD Scanner Tool usually rests with the car manufacturer in most cases, it can also be the prerogative of the car owner to make the choice of which tool will be used on his car. In the years of yore, OBD scan tool requirements stipulated that all cars must be fitted with a functioning OBD scan tool.
U380 OBD II car scanner

U380 OBD II Car Diagnostic Scanner Trouble Code Reader

The rule has not changed a bit with the introduction of more advanced OBD 2 and the EOBD 2 in Europe. What it now stipulates is that the car owner is more at liberty of selecting an appropriate tool for his use without having to rely on the manufacturer gadget.
Why is it so?

The need for standardization brought with it an open market system. initially, the manufacturer specific OBD scan tools were limited to given cars and required that the car owner bought new BMW ICOM the moment a new car brand would be bought. This was quite expensive and made most people to pile OBD scan tools in the house, some of which they didn’t use.

The reduction of emission and the need to have quick and efficient repairs was the main aim of the innovation regarding OBD scan tools. If the Heavy Duty Diagnostic was going to present a new front for delayed repairs, then it would not serve the purpose. The environmental protection agency (EPA) in the United States recommended for an electronic gadget which was standard and would not have these challenges.

The second generation onboard diagnostic scan tools were thus invented. These tools are among the best the automotive industry has seen because of the nature of their action. One tool can in fact be seen to work on several other cars without any trouble. In most instances, novices are found to have their use quite appropriate.

EOBD2 scanner

EOBD2 & OBD2 Diesel Diagnosic tool

The success seen with the second generation scanners is immensely attributed to the protocol coverage within them which makes them more compatible with newer car models and even older car models. This has led to their being seen as the best scan tools for use on the car.
Why OBD 2?

The OBD 2 machines have thus been rated highly as one of the best tools worth using if you want to have a smooth scan.

The reasons for OBD 2 preference are as follows;

Wide protocol coverage- while the old generation scan tools were known to cover almost all the known protocols within the span of the diagnostic scanner use. This fact has always given them great advantages in terms of compatibility.
Ease of use- with the OBD 2 the user may not have to hustle around looking for code meaning. This is mostly because most of them have a directory where all the codes read are translated. In addition, some have audio for relaying the code progress meaning and completion of the repair process.
Cost effective- by reducing the time taken by the mechanic on the car, these OBD scan tools have drastically reduced the repair time as well as the overall cost that a mechanic would charge. Moreover, most of them are cheap in terms of price.
Longer use- the OBD 2 scanner is known to have an updatability feature that is the most special thing about them. This can allow them to be used with newer cars. Moreover, by just downloading some of the software associated with these tools, one can turn any mobile devices into an OBD 2 Bluetooth scan tool.

With all these facts at hand, it is clear that the OBD 2 is among the best gadgets to use on the cars. The European version may b e the EOBD 2 but the purpose id the same. This however does not overrule all OBD 1 scan readers in the market. They are equally good but cannot be the best.

Of cars and car faults

Using cars has been an exciting thing since the innovation of wheels. Many people love their cars for the convenience they are known to provide. While the process of car use may be the most exciting, the prevalence e of car faults is usually something which is commonplace.

Car fault has been known to arise from different car areas. Some of which include:

The engine
The wheels

Engine faults

The Car Diagnostic Tool has been the major area which keeps the car moving. However much we may want the engine to remain in good condition, the car engine is the most common area of fault. Engine faults are caused by several factors which include heating, blockages and just mere cases of negligence.

car engine faults

Because of the combustion process, the car engine is bound to heat up and as a result need urgent cooling. The heating arise from the fuels which are used and the lack of ventilation. The car filters are usually placed strategically to help in reducing the oil clogging on the car system.

When the engine is clogged, it is bound to cause heat. Oxygen and water are usually some of the most important elements when this arises. The emissions of carbon dioxide in the course of the combustion usually cause the car engine to have the chocking effect.

Engine fault is also known to arise from other factors like the imbalances in the car engine pressure. The maintenance of the car engine pressure is quite important if the car engine were to have ‘good health’. The use of certain oils is some other contributors to the problem of temperature and pressure.
The car body

Car bodies are made of diverse metallic components. Aluminum and steel are some of the most commonly used materials in the car body industry. Aluminum is regarded to be lighter than its steel compatriot, steel is harder. The fact that aluminum does not rust as fast makes it to be used in most of the Auto Repair Software.

car body faults

The corrosive nature of natural forces usually eats away the metallic part of the car body. However, the aluminum is known to last longer than steel. A car with corroded body looks ugly and un-roadworthy. This in itself is a fault which needs urgent correction.
The wheels

Because it is the part which is in contact with the road, car wheels are the most important part of car movements.  Car wheel problems arise from the wheel alignment issues or just the mere fact that the bearings have failed.

the car wheels

When the problem is with the car wheel alignment, there is bound to be numerous vibrations which may bring a lot of discomfort to the car users. In fact, the car vibrations alone may make the use of the car unbearable.

When the bearings fail, the most prudent thing to know is the cause and how to rectify the fault. Because the bearings form an important part of the wheel movement, it may sometimes be a matter of just oiling the bearings or just replacing the balls within the b, if some are cracked.
How do we rectify car fault?

In the past, it would take ages to be able to identify and rectify certain areas of the car fault. Since the 1960s in California, the introduction of onboard diagnostic scan machines (OBD), which were basically meant to identify the car fault in the course if car use. The result has been the revolutionizing of the process of identification and correcting of the car faults.

The initial stages of the on board diagnostics only used the simple car engine readers whose scope was not large enough. This posed a big problem and so the introduction of the second generation scan machines (OBD II).

Most of the second generation scan tools are known for their efficient nature of getting the car fault readings. This has lessened the process of car fault identification and car repairs. OBD2 Scanner in essence are meant to reduce the cases of having faulty cars on the road.

Because of their universality, OBD II scan tools are known to be compatible with most of the car brands in the market. Their availability in the market has also never been in question given their stock on most of the online as well brick and motor stores.

So if you are one of those who are suffering from the numerous cases of car fault, getting yours is just a click away. Take that step and get yours, it would be the most ideal decision of your life.

Advice to the locksmith who wants to step into car key programming


These years, an increasing number of people want to engage in locksmith industry, many civil locksmiths also want to join. I summarize 6 pieces of advice to the locksmith who wants to step into car key programming, in the aspect of invest, key programmers and cutting machines and some more attentions.

Firstly, how much money and what ways to invest, it depends on your professional skills and budgets. Better ask for advice from the elder master and the experience locksmith. No device can do all, High price not means good quality, and not all machine is suitable for you. In order to avoid broking vehicle or making the vehicle can’t start, advise you choose the machines which have been proved that can work for a long time in the market, and among the same products which sold by many sellers, not the cheaper the saver, some sellers sell the products at a lowest price, but they don’t provide essential technical support, when you encounter problems they will not answer you, the money you save is meaningless. The more technical support you get, the more function the device can realize, therefore, the cheapest one is not suitable. Then what about the high-end tools, I have proved the most expensive tools Is not necessarily the best, such as the expensive Tango key pro, original AVDI, key pro M8 and more, they are all international tools and also very expensive, but actually the most expensive is not necessarily the best, the update operation is neither suitable for the junior locksmiths, the locksmith who has not enough budget will not afford to the update fee or the adapter fee. The freshman is not advised to invest the newest machines, for the senior locksmith they are experienced when they meet any problems and find the solution, but for the junior locksmith, when they meet any problem, they will have no any idea, if wrongly solved, the vehicle may be broken or can’t start, then you will be frustrated and lose confidence to program key. Therefore, if you are a junior locksmith, just wait until the senior locksmith prove the newest machines can work well. And you are suggested to start from the easier steps to the difficult steps, for example, firstly use the tool that needs not to remove the chip before use the tool that needs to remove the chip.

Secondly, one customer’s demands to the consumables is different from that of the other, some customers prefer to the cheap one, some to the original one and some to the easier one, therefore we need to supply the original products, the reequipped products and cheap products. But you are not suggested to deal with too many inferior products; otherwise the customers may less trust you and you lose the reputation

Thirdly, a grade store design will impress the customers, and the store with bad display will give the drivers bad impression that less profession and less reliability, then they are not willing to let you program his car. And you are supposed to be familiar with most brand car models, it is very bad to ask others or search the materials only after the driver drives the car to you, the more you know the more customers trust you.

Fourth, Inform and explain, clarify responsibilities. Avoiding unnecessary trouble

Take the battery change for example, when the car owner give us remote key and ask us to change the battery, usually we will directly change the battery and return to the driver, it seems to be easy, right? But, some auto locksmith react they encountered these incidents: after the battery changed, the remote control does not work, or the driver say the remote control distance is too short, even can’t start the vehicle. Why? There are three reasons: 1) the remote key code is lost and need to match again. 2) The remote key is damaged for the unprofessional operation by the locksmith. 3) The remote has problem before the driver gave you to change battery.

As for the reason three, I advice after you get the driver’s key, the first thing to do is to test whether the driver’s remote key can work or not and the remote has frequency or not. Or you have better change the battery within sight of the owner, and the driver will believe you do nothing accept change the battery, although it is the phenomenon of lack of trust between you and the driver, but it will avoid some unnecessary troubles.

Besides, before copy the new key you have better do the following work: 1) check if the key can work or not by inserting it into the car and try to start the car; 2) check if the warning light flash on the dashboard; 3) check if the light flashes when you use remote key to open or close the door; 4) if necessary, check the glass lift. To do the 4-steps work can avoid the misunderstanding between our locksmiths, according to my experience the car driver maybe thinks it is caused by our locksmith improper operation.

Fifth, In order to peacefully deal with the locksmith industry for a long time, please strict compliance with the law, because car decoding involve motor vehicles identity, the vehicle that lost all keys is required to record and verify identity, It is easy to check if any future problems. Do not trap into vehicle robbery and property dispute because of immediate benefits.

Finally, advice you make some locksmith friends, one good locksmith friend prior to ten key programming machines, as long as you are willing to learn and keep passion, your friends will help you when you have troubles during daily work.

According to my years of experience, I suggest you some Obd2 Key Programmers according to different car models and key chip.
1)Remote key programmer: H618 and KD600
2)Decoding machine: CI-PROG 300+, A168, key pro M8, X100
3)key programmer for 4th immobilizer system: VVDI2, DATA Smart3, original AVDI
4)chip read and writing machine: AD900, 884 and Tango
5)BMW key programmer: BMW OBD, AK300, BMW AK91
Mercedes Benz key programmer:  AK500, MB2
6)the key cutting machine: cheap working Condor XC-007 made in China, original expensive 994 or VIP

In conclusion: which one tool to buy, it depends on your budget and needs, wish you earn more profits with less investment.
