OBD2 Engine Code Readers

All engine code readers are designed to work with OBD2 protocols. This means they can read and clear engine-related trouble codes (Check Engine Light), display live engine parameters (like RPM, coolant temperature, or oxygen sensor data), and run emissions readiness checks.

What is OBD2?

OBD2 (On-Board Diagnostics II) is a universal standard introduced to help technicians and drivers diagnose issues with modern vehicles. It allows scan tools and code readers to communicate with the car’s Engine Control Unit (ECU) and retrieve information such as trouble codes, live sensor data, and emissions status.

OBD2 Compliant Cars in Australia

Our engine OBD2 code readers are compatible with vehicles that use standard OBD2/EOBD protocols. You can check if your car is covered by visiting our Australia OBD2 Compatibility List to find out if your car is covered.
