Sometimes, it can be really helpful when telling you the protential issues that can come out in the near future, help you to fix it before any real brokedown situations take place in the roads!

The OBD2 can also help to save a lot of time, and money if you bring your car to a mechanic man to have a total check or repairing. All of oil emisstions are well in control of this tool too. If any emission come up in random formulas, it will force shut-down and stop the emission process.

OBD means on-board diagnostics, so that they can communicate with your on board computer too, to give you very detaied information about the status of your car. Therefore, you can base on these knowledge to detect where the problem is rooted from. You can control in hand all the systems in your car, even the current performing or emission system. Of course I do not mean by some abnormal situations when the tool can not handle with. But it seldom happens, so do not worry much, a machine can never be perfect.

The process of an OBD2 reader is, they will get and clarify genetic codes, also with the pending codes to display them in a understandable in a screen. Sometimes there can be a connector device to connect a tool with a laptop or computer to be showed on.Then you can easily read all those information. This tool is handheld, and small, so that we can bring it together easily, without taking up much space, or affecting other normal functions of the car.


You should remember that there is no way an OBD2 scanner tool can be suitable with any kind of car! Therefore, there are tons of genres, types or functions that can be choosed from, in fitting with every kind. There is a famous tool recommended, Actron CP9680 AutoScanner Plus®. It is compatible with 1996 or newer vesions of import, domestic, diesel and hybrid vehycles, as well as being compliant with the 1995, 1996 OBD2 models. It has a code connect system to show a comprehensive load of database. A kind of software helps you a lot in using OBD2 tool.

Moreover, the better functions of OBD2 can be automaticly repairing all the small errors. Those errors (or faulty codes) of the car can be displayed in a numeric order by the OBD2 CAN tool operations.

Tips for buying a suitable OBD2 scan tool

Nowadays, you can easily find OBD II from any kind, any genre available from the market. The companies joining this market is getting more and more, making the number of competitors increases so fast. The prices range is therefore more diverse. However, some big companied still keep the high prices successfully, because they have advantageous competitive features. In general, the common prices are from 250-2500$. To get an OBD II which values for your money, you had better need to bear in minds some tips when purchasing as belows.

Compability of the OBD II

You first need to focus on this feature: Is that OBD II scan tool model is compatible to your hardware or your technical system. Though the OBD II compliant vehicles, the hardware can communite with diagnostic system to automatically sync with the other parts. All of system parts are standardized, so that everything goes in pairs or in groups together. There is a type called “universal scanners”, means they can fit all three hardwares. Howevers, sometimes the designs can be changed and it is up to the manufacturers. Take the Chevrolet with specified scanner models as a example.


Technical parameters

The technical parameters also matters when we decide to choose a scan tool. It is in the manuals supported by the brands. We can not compare one with another because there is no common standard available in the market. With some models like Clymer Repair Manuals, the Environmental Protection Agency of United States mandate a standard, according to some emission readings. The J1979 specification clarified this legislation. Nevertheless, with the low-enfd tools, they can not meet all of these features. It can be fine, if you use those basic tools in most countries, but meet troubles if in the American territories.

Upgradability of item

Whether it is able to update or not is another important factor. The car companies release modern and new car models every period of time, so features to be enhanced should be upgradable too. Only by that, we can use or repurchase a new technology items. However, the basic scan tools which can have really low standard would not be able to upgrate. As a result, buying an expressive tool is more pragmatic and realistic.

Built-in help features

Moreover, the inside features of a tool are very important too. You should consider the right outboard engine frame, which can define DTCs,… You can throw away spare parts or confusing details if you want, and tell it with the saleman. Sometimes you can be confused, and frustrated by the hard work of deciphering scan results.


Data logging and storage mechanisms

You need to be careful with the logging. Also remember to choose ones which have storages, in case the car did not left the garage. Done. However I know someone out there have no an idea to be join. Do not worry, you can consult a expert.

We wish these tips are helpful to you, because we extract the very main point from all our experience. Wish you have a good trip and choose a good company – a scan tool.

The most difficult part of all time is deciphering and translate the numeric codes from a car engine into the language that we can understand. Luckily, OBD2 tool is invented exactly for those functions. You needn’t hire a mechanics to understand what your car is saying. To begin with more detaied explanation, any information has to feed into a connector, with reports data as OBD or OBD2 codes. As in the past, a technician used to collect all data first with an designed engineering tool, something has the scanning tasks. All these information would be interpreted with the codes. Now he could already seek for the reasons of breaking or errors. It therefore even takes longer for prepairing process.
