You know for sure that the technology embedded in our cars become more and more complex day by day. All types of processing modules, electronic ignition controllers and sensors work all the time to monitoring and ensuring the good functioning of all systems of our vehicles. They also inform the driver the appearance of any problem, no matter how small. For all this set of tools we call OBD - On Board Diagnostics.


You remember, I believe, when the first warning lights began to appear in the dashboard of your car, around the early 80s. Those days, that lights only served to state the existence of a problem, such as an oil spill or a battery with less charge than indicated. The problem is they do not provide any sign about the origins and nature of the problem encountered. This was just the start of the use on a massive scale OBD technology.


The incredible OBD Tools - GM 12pin connector History

Let’s take a look now at the interesting history of OBD tools. Do you know that it begins around the late '60s? Check it out:

· In 1969, Volkswagen introduced the first onboard computer system into its Type 3 models. This system also had scanning capabilities.

· In 1975 Datsun introduces the onboard computer in their consumer vehicles.

· In 1980, General Motors began to use its proprietary interface and a specific protocol which is called Engine Control Module (ECM) on its vehicle assembly line.

· In 1991, The California Air Resources Board (CARB) demands that all cars sold in the USA have onboard some OBD system. These requirements have become known as OBD-I.

· In 1994, to attend a state-wide emissions testing program, CARB introduces the OBD-II specification for all cars sold in California after 1996.

· In 1996, the OBD-II specification was made mandatory for all vehicles sold in the United States.

· In 2001, Europe turns the EOBD (European On Board Diagnostics), a local version of OBD-II mandatory for all gasoline vehicles sold in the European Union. In 2004 for Diesel vehicles.


The Future

The Modern OBD tools - GM 12pin to OBD1 OBD2 connector, different from the old ones, using some standardized digital communication ports which enable technicians and mechanics connect a scanner or computer to the vehicle to get valuable information that allow easier and cheaper to identify and repair existing problems. These are the same systems that let you know while driving, for example, things like the current fuel consumption or how many miles you can still catch up with the fuel remaining in the tank.


If today OBD tools allow us to control and repair our cars with greater ease, the future will certainly be exciting. These systems - OBD2 connector Adapter Daewoo Cable will soon replace the act of driving, leaving us free to read a book or check our emails while traveling comfortably and safe across the town.
