How can a code saving device be conneceted to a vehicle?

A code-saving device can be connected to a vehicle via the On-Board Diagnostics II (OBD-II) port, which is typically located under the dashboard near the driver's seat. Once plugged in, the device can interface with the vehicle's electronic systems to retrieve and store diagnostic trouble codes (DTCs) and other relevant data. Some devices may also connect wirelessly through Bluetooth or Wi-Fi to a smartphone or computer for easier access and data management. This allows users to monitor vehicle performance and troubleshoot issues efficiently.
