What is Car OBD2 Scanner?
Car OBD2 Scanners are essential electronic devices used to interface with a vehicle's on-board diagnostics system. They allow owners to read diagnostic trouble codes (DTCs) produced by the car's computer when a fault is detected. This technology provides a clear window into the engine's performance and health.
These tools connect to a standardised port usually located under the dashboard of most cars produced after 1996. By retrieving data from the Engine Control Unit (ECU), they can identify issues ranging from faulty sensors to serious mechanical failures. This process is vital for accurate troubleshooting and repair.
