Can I clear error codes with an OBD scanner?

Yes, an OBD scanner can clear error codes. When connected to a vehicle's OBD port, the scanner communicates with the onboard computer system to retrieve and display diagnostic trouble codes (DTCs) associated with malfunctions. These codes indicate specific issues within the vehicle. A reliable OBD scanner often includes the ability to erase or clear these error codes once they have been diagnosed and fixed. Clearing the error codes is a necessary step to turn off the check engine light after addressing the underlying problem. Additionally, it allows users to verify if the issue has been successfully resolved. It is important to note that clearing the codes does not fix the problem itself; it only resets the system by removing the stored error codes.
