Some Points to Know before Choosing a Right OBDII Scanner

July 19, 2010 - PRLog -- Nowadays, there are a lot of OBDII scanners available in the market and the number is still increasing. Buying a scanner is easy, but figuring out which one fits your car takes some more consideration. Finding the scanner that is right for your car is not easy because there are so many different ones to choose from. In order to get the best value for your money, you need to remember some points in choosing a scanner for your car.
Firstly, you should take the compatibility of the OBDII scanner that you are about to purchase into consideration. It is true that OBDII is a standardized auto diagnostics, but there are actually three varying types of hardware communications utilized by OBD II compliant vehicles. There are OBDII scanners that support all three hardwares and they are considered as the universal scanners. There are also some that are specific depending on the manufacturer. For instance, the Chevrolet Company uses a scanner that they have specified.
Secondly, it is also important to determine the parameters that the repair manuals support. Not all of the scanners in the market are equal or even comparable with each other. The Environmental Protection Agency of United States mandated an OBDII standard requiring for some emission related readings to be supported by Clymer Repair Manuals models. This legislation is defined by the J1979 SAE specification. However, there are some low-end tools that do not have such features making them inapplicable to American Standards. It may be ok to use these very basic tools if you are in some other countries but you should find means to comply with it if you are in American territories.
Another important point you should consider is the updatability of the automotive repair manuals that you are buying. Car companies release new models every year with enhanced features so OBDII scan tools should be updatable as well to support the changes on the new vehicles.
Furthermore, the built-in help feature of the scanner should also be considered. The outboard engine repair that you will choose should be able to define the DTCs so as to get rid of confusions on the part of the car owner or mechanic. In addition, this will also deliver the owner from time-delays and frustrations caused by the difficulty of deciphering the scan results. Last but not the least is the data logging and storage mechanisms of the OBD II scan tool. It is very dangerous to keep your eyes on the scan tool display while conducting a roadtest. You should choose a scanner that allows for storage of data while your car hasn't left your garage yet. If you are totally unfamiliar with the specs then you can consult a car expert or mechanic.
Something else to keep in mind is that a scanner by itself cannot fix anything. It takes a brain to operate and use the information provided by the tool. In conclusion, the more time and research you put into a scanner tool, the better satisfied you will be.
