What is OBD2 and how does On-Board Diagnostic software work?

car illustration

On-Board Diagnostics, or OBD, is a computer-based system built into modern passenger cars that monitors emission related controls and 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 (ECU). The OBD2 system offers valuable information, including diagnostic trouble codes, when troubleshooting problems.

OBD diagnostic software communicates with the car and reads the diagnostic information from the car. For the communication, a small OBD adapter is needed in addition. The adapter is attached to a car's OBD2 port. It acts as a bridge between your computer/mobile and the car. Using the adapter, OBD software can communicate with the car and present the diagnostic information in user friendly way. It is the software that brings the real value for you. That's why we created OBD Auto Doctor.

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 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.
