How Does an ELM327 Adapter Work?

The ELM327 itself is a microcontroller chip that interprets the OBD2 protocols used by your vehicle. OBD2, which stands for On-Board Diagnostics, is a standardized system found in most cars manufactured after 1996. The ELM327 chip translates the complex data from your car’s ECU into a format that can be easily understood by diagnostic software.

When you plug an ELM327 adapter into your car’s OBD2 port, it establishes communication with the ECU. You can then use a compatible app or software on your device to send and receive data. This communication allows you to access information about your car’s engine performance, emissions, fuel economy, and more.
