OBD Diagnostic Port Tester 

The purpose of the Advanced OBD diagnostic port tester is to make a full test of all kinds of 12V car diagnostic ports. It cannot be used to diagnose defects on the car, but nonetheless using it has a good economic effect, as it saves time and protects expensive diagnostic scanners against damage due to malfunctions in the car's diagnostic port or problems with the car’s electrical system. A great cost effective time saver and eliminates the risk of damage to diagnostic equipment.

Almost all professionals working in the automobile service sector have had problems at one time or another with diagnostic port problems, an example is the now well know VW aftermarket radio problem where battery voltage is sent to the K line and can damage expensive diagnostic equipment or even worse destroy it. If you haven’t personally had this problem, that does not mean that you are protected in some way. The only way to be safe is to use such a tester.

Furthermore with the help of the Advanced OBD Diagnostic Port Tester you can easily find if there is an interrupted supply wire connected to the diagnostic port, when having communications problems with the diagnostic equipment connected to the car and you can also detect which is the interrupted wire – either chassis ground cable or positive from car battery.

With the help of the Low Battery LED indicator you can see if the problem is because of a low board voltage in the car.

The Ditex OBD Diagnostic Port Tester can be used to test all types of old diagnostic ports used before the OBD2 standard. All kinds of adaptors for the specific diagnostic port that have an OBD2 female port can be used for this purpose.
