You first need to establish a successful connection to your vehicle, by specifying its ODB-II protocol and the connection method you prefer (be it bluetooth, serial port or WiFi). The graphic interface of OBD Auto Doctor is highly intuitive so that even computer novices can easily interpret the data presented by this ODB (On-Board Diagnostic) application. OBD Auto Doctor is a specialized software solution that can help you diagnose your vehicle by connecting it to the PC via a ELM327-based OBD-II adapter. However, if you want to save some money or you want to try and fix it yourself, you first need to determine the exact location of the defect or of the malfunction. When you car breaks down or when something about it does not work as it should, the smart thing to do is to take it to a mechanic who will fix it.
