• ELM327: This is the microchip that acts as the translator between your car’s OBD2 system and your smartphone, tablet, or computer.
• Car Diagnostic Scanner: This is the device (often a small Bluetooth adapter) that houses the ELM327 chip and plugs into your car’s OBD2 port, usually located under the dashboard on the driver’s side.

In simple terms, OBD2 ELM327 car diagnostics uses a small, affordable device to read data from your car’s computer and present it to you in an understandable way.
