On-Board Diagnostics, or OBD, is a computer-based system built into modern automobiles that monitors emission related controls, performance of the engine, and detects malfunctions. OBD-II systems provide access to the health information of a vehicle and access to numerous parameters and sensors from the Engine Control Unit. The OBD2 system offers valuable information, including diagnostic trouble codes, when troubleshooting problems.
OBD-II scan tool is a device that is used for communicating with a car's OBD system and accessing the OBD information. In other words, a scan tool is a small adapter attached to a car. Our OBD diagnostic software talks to the car via this adapter. It is the software that brings the real value for you. That's why we created OBD Auto Doctor.
How does the OBD Auto Doctor diagnostic software work?
To start communicating with your car, you need to have ELM327-based adapter and a OBDII compliant car. Just connect the OBDII adapter to the physical 16-pin OBD connector plug located near the dashboard (typically below the streering wheel), launch the OBD2 software, and you are ready to go. The connection between the interface and the software can use bluetooth, WiFi, serial port or USB connection depending on the type of hardware you have.
