OBD2 software is a type of diagnostic software that will help you or a mechanic to identify the problem with the car and then fix it.  Most of this type of software is found in modern cars manufactured after the mid-90’s.  It will often interface with the vehicles on board diagnostic computer.  Most of the basic concepts  of the internal combustion engine has not changed much since cars were first manufactured today’s cars have been made more efficient, cleaner, and safer due to the computer technology of today and modern electronics.

Vehicles cannot fix themselves so this is where the OBH II software comes into play.  Using the on board computers they can generally identify any problems before you would notice them.  This type of software helps to bridge the gap between machines and man to help professional and amateur mechanics to identify easily and quickly any problems with their vehicles.  Since 1996, all vehicles that have been sold in the United States have to have an internal diagnostic computer along with the interface to access the data from the computer, sensors, and emissions control systems. 

These sets of standards are referred to as on board diagnostics II (OBD II).  These have replaced the earlier systems that different for each car manufacturer.  When this software came on the market, it opened the doors for software and tolls that were able to interface with all manufacturers cars.  Previously this data was only available to dealerships but now anyone can access the information, from do-it-yourself mechanics to the mechanics working in auto repair shops or are self-employed.

Now OBD2 software can interface with an OBD II system, which is available on almost every platform from smart phones to laptops.  Although the capabilities of these programs vary most are able to read the diagnostic trouble codes (DTCs) that could cause your check light to come on.  If you are not sure where this light is located, it is normally found on your dashboard.  These codes provide specific information about mechanical and electric problems in a car or truck.  Sometimes it is possible that you can reset or read a trouble code without needing to take your car to your mechanic.

In addition to receiving trouble codes, the OBD2 software can use the OBD scanners and card readers to monitor the functions of the vehicle.  Using this software, you can send a message to the electronic devices requesting more information about the vehicle from ignition timing to coolant temperature.  A DFC can also diagnosis problems that do not trigger the check engine light to come on but can provide information in regards to gas mileage that is also just as important.
