OBD2 scanner is a tool used for car fault diagnosis, which can read and clear the vehicle’s fault codes. It connects to the car’s OBD (on-board diagnostics) interface to obtain real-time data from the engine and other systems to help users identify potential problems.
Main functions of OBD2 scanner
1. Read fault codes: OBD2 scanner can read fault codes in the car’s engine system, which are usually generated by the vehicle’s computer and indicate a specific fault or problem.
2. Clear fault codes: Users can use the scanner to clear the fault code of the problem that has been solved, thereby extinguishing the fault light on the dashboard.
3. Real-time data streaming: The device is able to display real-time data from various sensors of the car, such as engine speed, vehicle speed, throttle position, etc., to help users monitor the status of the vehicle.
4. I/M readiness check: This function can check whether the vehicle passes the emission test and ensure that all monitoring systems are working properly.
5. Freeze frame data: When a fault occurs, the OBD2 system will record real-time data when the fault occurs, which helps technicians analyze the problem.
Benefits of using OBD2 scanner
Convenience: Users can perform preliminary diagnosis at home without going to a repair shop.
