A PC-based OBD analysis tool that converts the OBD-II signals to serial data (USB or serial port) standard to PCs or Macs. The software then decodes the received data to a visual display. Many popular interfaces are based on the ELM327 or STN [ 41 ] OBD Interpreter ICs, both of which read all five generic OBD-II protocols.
The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors.

OBD 1 vs OBD 2 the vehicle will also dictate what the scan tool is able to display. If the vehicle is equipped with OBD 1 it will have significantly less available data when compared to a vehicle equipped with OBD 2. [2] When a vehicle detects a problem, it generates a DTC code which is a unique code that corresponds to the specific problem ...
Modern vehicles have a diagnostic interface for off-board diagnostics, which makes it possible to connect a computer (client) or diagnostics tool, which is referred to as tester, to the communication system of the vehicle. Thus, UDS requests can be sent to the controllers which must provide a response (this may be positive or negative).
